2003-02-24  Jonathan Larmour  <jifl@eCosCentric.com>

        * cdl/ser_mn10300.cdl: Remove irrelevant doc link.

2001-09-10  Jonathan Larmour  <jlarmour@redhat.com>

        * cdl/ser_mn10300.cdl:        
        Fix 234000->230400 typo.

2000-08-01  Jonathan Larmour  <jlarmour@redhat.co.uk>

        * src/mn10300_serial.c (mn10300_serial_set_config): Now use keys to make
        more flexible.

2000-06-22  Hugo Tyson  <hmt@cygnus.co.uk>

        * cdl/<yournamehere>.cdl: Remove the comment on the empty
        include_files directive; the tools now support this correctly.
        This keeps internal include files internal.

2000-04-11  Hugo Tyson  <hmt@cygnus.co.uk>

        * cdl/ser_mn10300.cdl: Change the parent from CYGPKG_IO_SERIAL
        (which is enabled most of the time) to CYGPKG_IO_SERIAL_DEVICES
        (which is not...) thus allowing convenient control independent of
        platform.  Also enable all individual devices by default, now, so
        that they can be enabled simply by enabling the above new parent.

2000-04-07  Hugo Tyson  <hmt@cygnus.co.uk>

        * ecos.db: Re-organize device packages.  This is a massive change
        involving deleting all the sources for serial and ethernet drivers
        from where they used to live in
            packages/io/serial/current/src/ARCH/PLATFORM.[ch]
            packages/net/drivers/eth/PLATFORM/current/src/...
        and reinstating them in
            packages/devs/serial/ARCH/PLATFORM/current/src/...
            packages/devs/eth/ARCH/PLATFORM/current/src/...

        All these new packages are properly defined in ecos.db, and are
        all of type "hardware" so that a "target" can grab them.
        
        This directory layout is descriptive of the devices we have right
        now, arch and platform are separate levels just to make it easier
        to navigate in the filesystem and similar to the HAL structure in
        the filesystem.

        It is *not* prescriptive of future work; for example, the mythical
        common highly-portable 16550 serial driver which works on many
        targets would be called "devs/serial/s16550/current", or a serial
        device for a particular board (cogent springs to mind) that can
        work with different CPUs fitted is "devs/serial/cogent/current".

        Changelogs have been preserved and replicated over all the new
        packages, so that no history is lost.

        The contents of individual source files are unchanged; they build
        in just the same emvironment except for a very few cases where the
        config file name changed in this movement.

        Targets in ecos.db have been redefined to bring in all relevant
        hardware packages including net and serial drivers (but the newly
        included packages are only active if their desired parent is
        available.)
        
        The names of CDL options (and their #defines of course) stay the
        same for the serial drivers, for backward compatibility.

        * templates/*/current.ect: these have had CYGPKG_IO_SERIAL added
        rather than it being in (almost) all target definitions.
        
2000-04-05  Jonathan Larmour  <jlarmour@redhat.co.uk>

        * src/common/tty.c (tty_read): CRLF conversion should use \r\n not \n\r
        (tty_write): Similarly

        * include/ttyio.h: Update CYG_TTY_IN_FLAGS_CRLF and
        CYG_TTY_IN_FLAGS_CRLF to match

2000-03-31  Jesper Skov  <jskov@redhat.com>

        * cdl/ser_sh_edk7708.cdl: Limit legal baud rate range.
        * src/sh/sh_sci_serial.c: Use baud rate macro instead of hardwired
        constants.

        serial_devio => cyg_io_serial_devio

2000-02-10  Jonathan Larmour  <jlarmour@redhat.co.uk>

        * src/mn10300/mn10300_serial.c: Ensure all CYG_HAL_MN10300_*
        preprocessor conditionals use the correct CYGPKG_HAL_MN10300_AM3* form
        now.    

2000-02-03  Jesper Skov  <jskov@redhat.com>

        * src/powerpc/quicc_smc_serial.c: CYG_HAL_POWERPC_x->CYGPKG_...

2000-02-02  Jonathan Larmour  <jlarmour@redhat.co.uk>

        * src/arm/aeb_serial.h: Rename lower case register macros to REG_ upper

        of line (size must be 'signed' for compare to work).

2000-01-19  Hugo Tyson  <hmt@cygnus.co.uk>

        * cdl/*.cdl: Add descriptions to a number of options &c which were
        lacking same, also tidied up other typos as noticed en passant.

2000-01-17  Gary Thomas  <gthomas@cygnus.co.uk>

        * src/common/tty.c (tty_read): Avoid echoing "backspace/erase" at

        * src/common/serial.c (serial_write): Avoid potential deadlock if
        transmit start actually sends enough characters to signal cond wait.

2000-01-03  Gary Thomas  <gthomas@cygnus.co.uk>

        * include/serial.h: Fix namespace pollution - 
        serial_devio => cyg_io_serial_devio
        serial_callbacks => cyg_io_serial_callbacks

        * src/mips/tx3904_serial.c: 
        * src/mips/vrc4373_serial.c:

        * src/common/haldiag.c: 
        * src/common/serial.c: Fix namespace pollution - 
        serial_devio => cyg_io_serial_devio

1999-12-06  Gary Thomas  <gthomas@cygnus.co.uk>

        * src/arm/pid_serial_with_ints.c (pid_serial_DSR): Add loop to handle
        case where an interrupt represents multiple events.

1999-11-19  Gary Thomas  <gthomas@cygnus.co.uk>

        * src/powerpc/quicc_smc_serial.c: Channel select for SMC2 was wrong.

1999-11-18  Gary Thomas  <gthomas@cygnus.co.uk>

        * include/pkgconf/io_serial.h: Remove mention of 7209/7212.

1999-11-03  John Dallaway  <jld@cygnus.co.uk>

        * cdl/io_serial.cdl: Define build options.

1999-10-26  Jesper Skov  <jskov@cygnus.co.uk>
        * tests/serial5.c (serial_test): Reduce speed in thumb mode.

        * src/arm/pid_serial.h: Added BE support.

        * src/PKGconf.mak: Use CYGPKG_<> instead of CYG_<> to control what
        needs to be compiled.

1999-10-25  Gary Thomas  <gthomas@cygnus.co.uk>

        * src/arm/pid_serial.h (ISR_RxTO): Define - character received but
        not handled "promptly".

        * src/arm/pid_serial_with_ints.c (pid_serial_DSR): Handle rcv interrupts
        properly (can't ignore them even with TO bit set).

        * src/arm/cl7211_serial.c (cl7211_serial_rx_DSR): Need to handle all
        input (empty input FIFO) otherwise characters get dropped.

1999-10-15  Jesper Skov  <jskov@cygnus.co.uk>

        * tests/ser_test_protocol.inl: Removed AEB rev C change. Was bogus.

1999-10-11  Nick Garnett  <nickg@cygnus.co.uk>

        * tests/ser_test_protocol.inl: Added configury for VR4300 testing.

1999-09-28  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/powerpc/quicc_smc_serial.c (quicc_smc_serial_init): Correct
        value supplied for interrupt priority - it may be unused, but it
        is asserted for range.  Initialize the diagnostic channel if on an
        MBX and if NOT using SMC1 ourselves, to ensure that diag output
        and built-in stubs work correctly; otherwise reset the quicc and
        ignore SMC1 as before.  Fix various warnings, mostly about
        casting/arg-passing/assigning away volatile.

1999-08-31  Jesper Skov  <jskov@cygnus.co.uk>

        * tests/ser_test_protocol.inl: Define dummy crash ID.

        * tests/serial3.c: 
        * tests/serial4.c: 
        * tests/serial5.c: 
        * tests/PKGconf.mak:
        Require kernel and kernel C API.
        
1999-08-17  Nick Garnett  <nickg@cygnus.co.uk>

        * src/mn10300/mn10300_serial.c: Added a simple implementation of a
        receive FIFO to try and reduce the overhead of receiving bytes.

1999-08-16  Jonathan Larmour  <jlarmour@cygnus.co.uk>

        * src/PKGconf.mak:
        * src/mn10300/mn10300_serial.c:
        * tests/ser_test_protocol.inl:
        Rename all am32 -> am31

1999-08-12  Nick Garnett  <nickg@cygnus.co.uk>

        Imported following changes from development branch:
        
    1999-08-11  Nick Garnett  <nickg@cygnus.co.uk>

        * tests/serial5.c: Modified config test for boards that need a lower
        speed for this test.

        * tests/ser_test_protocol.inl: Removed 14400 baud tests for all
        MN10300 variants. The MN10300 cannot currently do this speed.

        * src/mn10300/mn10300_serial.c: Tidied up the transmit interrupt
        enable/disable code to be variant specific.

        * include/pkgconf/io_serial.h: Undid Jonathan's change, since the
        same options are used for all MN10300 variants.
        
    1999-08-10  Jonathan Larmour  <jlarmour@cygnus.co.uk>

        * include/pkgconf/io_serial.h:
        Reparent CYGPKG_IO_SERIAL_MN10300 from under CYGPKG_HAL_MN10300 to
        CYGPKG_HAL_MN10300_AM32_STDEVAL1 since it's stdeval1 specific

    1999-08-04  Nick Garnett  <nickg@cygnus.co.uk>

        * tests/ser_test_protocol.inl:
        Changed names of MN10300 defines tested. Added AM33 definitions.

        * src/mn10300/mn10300_serial.c:
        Modified driver to work on am33 too. This simply requires some
        alternate definitions of things like register addresses and some
        bits in them plus some extra parameterization of some register
        values.

        * src/PKGconf.mak:
        Added am33 to list of architectures supporting serial lines.
        
1999-07-28  Gary Thomas  <gthomas@cygnus.co.uk>

        * include/pkgconf/io_serial.h: Update descriptions to be more
        generic (CL7x11 instead of CL7211).

1999-07-28  Jonathan Larmour  <jlarmour@cygnus.co.uk>

        * include/pkgconf/io_serial.h: Correct typos in CDL description
        for serial port 2 driver

1999-07-26  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/arm/ebsa285_serial.c: New file: device driver for the serial
        device of the Intel StrongARM EBSA-285 evaluation board.

        * include/pkgconf/io_serial.h (CYGPKG_IO_SERIAL_ARM_EBSA285):
        Config for it.

        * src/PKGconf.mak (EXTRAS_COMPILE): Compile it.

        * tests/ser_test_protocol.inl (TEST_SER_DEV): Enable testing of it.

1999-07-08  Jesper Skov  <jskov@cygnus.co.uk>

        * tests/ser_test_protocol.inl (change_config): Changed implementation.

1999-06-27  Gary Thomas  <gthomas@cygnus.co.uk>

        * src/powerpc/quicc_smc_serial.c (quicc_smc_serial_init): More robust
        initialization, with data cache disabled.  This seems to fix the
        random failures described below.

        * tests/ser_test_protocol.inl: Add configuration for QUICC/MBX860.
        Added some delays in the configuration change code to make QUICC
        happy [didn't help much although the manual says they are required].

        * src/powerpc/quicc_smc_serial.h (UART_BITRATE): Rewrote macro to 
        match what the Linux driver uses - still doesn't work well, though.

        * src/powerpc/quicc_smc_serial.c: Lots of changes trying to get the
        serial driver working and robust.  At this point it works quite well,
        using the default buffer sizes.  Changing from the defaults seem to
        easily break it though, certainly on input.  Also, changing the baud
        rate seems to not work reliably.

        * src/common/serial.c: Add some tracing/debug info to try and debug
        problems with QUICC serial driver.  These are hard disabled with
        "XX_" prepended to "CYGDBG_DIAG_BUF".  Enabling them gives information
        about how/when data are delivered from the serial driver.

        * include/pkgconf/io_serial.h: Adjust limits and defaults on number and
        size of buffers with values that seem to work.

1999-06-21  Jesper Skov  <jskov@cygnus.co.uk>

        * src/sh/sh_sci_serial.c: Rearranged inclusion of .inl file a bit
        to avoid compiler warnings.

1999-06-21  Gary Thomas  <gthomas@cygnus.co.uk>

        * include/pkgconf/io_serial.h: Fix CDL for number of buffers.

        * src/powerpc/quicc_smc_serial.c: Force number of buffers = 1.

1999-06-20  Gary Thomas  <gthomas@cygnus.co.uk>

        * include/pkgconf/io_serial.h: Some clean up (removed commented
        obsolete CDL parenting structure).
        Add support for Motorola PowerPC QUICC/SMC.

        * src/arm/cma230_serial.c: 
        * src/arm/cl7211_serial.c: 
        * src/arm/aeb_serial.c: 
        * src/arm/pid_serial_with_ints.c: Use #include to get 'diag_printf()'
        prototypes.

1999-06-17  Gary Thomas  <gthomas@cygnus.co.uk>

        * src/arm/cl7211_serial.c (cl7211_serial_start_xmit): Fix race which
        cause xmitter to get stuck.

1999-06-16  Jesper Skov  <jskov@cygnus.co.uk>

        * src/sh/sh_serial.c:          [removed]
        * src/sh/sh_sci_serial.c:      [added]
        * src/sh/sh_sci_7708.inl:      [added]
        * include/pkgconf/io_serial.h: 
        * src/PKGconf.mak (EXTRAS_COMPILE): 
        * tests/ser_test_protocol.inl: 
        Renamed CDL options and restructered driver.
        Fixed CDL typo.
        
1999-06-04  Jesper Skov  <jskov@cygnus.co.uk>

        * include/pkgconf/io_serial.h: Fixed CDL string for BAUD rate option.

1999-06-04  Gary Thomas  <gthomas@cygnus.co.uk>

        * tests/ser_test_protocol.inl: Disable testing at 115200
        for Cogent CMA230 (ARM).

        * src/arm/cma230_serial.c: Fix interrupt for port B.

1999-05-31  Jesper Skov  <jskov@cygnus.co.uk>

        * src/sh/sh_serial.c: Fixed receive interrupts and added handler for
        error interrupts.

1999-05-28  Jesper Skov  <jskov@cygnus.co.uk>

        * io/serial/current/src/PKGconf.mak:
        * io/serial/current/tests/ser_test_protocol.inl:
        * include/pkgconf/io_serial.h: 
        Renamed SH platform package to edk7708.

1999-05-27  Jesper Skov  <jskov@cygnus.co.uk>

        * tests/ser_test_protocol.inl: Added ability to change options in
        host software.

1999-05-27  Jonathan Larmour  <jlarmour@cygnus.co.uk>
