Summary:
This is the value to write into CCSR offset 0x18600
according to the A004510 workaround.
+ CONFIG_SYS_FSL_DSP_DDR_ADDR
+ This value denotes start offset of DDR memory which is
+ connected exclusively to the DSP cores.
+
CONFIG_SYS_FSL_DSP_M2_RAM_ADDR
This value denotes start offset of M2 memory
which is directly connected to the DSP core.
+ CONFIG_SYS_FSL_DSP_M3_RAM_ADDR
+ This value denotes start offset of M3 memory which is directly
+ connected to the DSP core.
+
CONFIG_SYS_FSL_DSP_CCSRBAR_DEFAULT
This value denotes start offset of DSP CCSR space.
+ CONFIG_SYS_FSL_DDR_EMU
+ Specify emulator support for DDR. Some DDR features such as
+ deskew training are not available.
+
- Generic CPU options:
CONFIG_SYS_BIG_ENDIAN, CONFIG_SYS_LITTLE_ENDIAN
CONFIG_SYS_I2C_SOFT_SPEED_4 and CONFIG_SYS_I2C_SOFT_SLAVE_4
for defining speed and slave address
+ - drivers/i2c/fsl_i2c.c:
+ - activate i2c driver with CONFIG_SYS_I2C_FSL
+ define CONFIG_SYS_FSL_I2C_OFFSET for setting the register
+ offset CONFIG_SYS_FSL_I2C_SPEED for the i2c speed and
+ CONFIG_SYS_FSL_I2C_SLAVE for the slave addr of the first
+ bus.
+ - If your board supports a second fsl i2c bus, define
+ CONFIG_SYS_FSL_I2C2_OFFSET for the register offset
+ CONFIG_SYS_FSL_I2C2_SPEED for the speed and
+ CONFIG_SYS_FSL_I2C2_SLAVE for the slave address of the
+ second bus.
+
+ - drivers/i2c/tegra_i2c.c:
+ - activate this driver with CONFIG_SYS_I2C_TEGRA
+ - This driver adds 4 i2c buses with a fix speed from
+ 100000 and the slave addr 0!
+
+ - drivers/i2c/ppc4xx_i2c.c
+ - activate this driver with CONFIG_SYS_I2C_PPC4XX
+ - CONFIG_SYS_I2C_PPC4XX_CH0 activate hardware channel 0
+ - CONFIG_SYS_I2C_PPC4XX_CH1 activate hardware channel 1
+
additional defines:
CONFIG_SYS_NUM_I2C_BUSES
If not defined, then U-Boot uses predefined value for
specified DTT device.
- CONFIG_FSL_I2C
-
- Define this option if you want to use Freescale's I2C driver in
- drivers/i2c/fsl_i2c.c.
-
- CONFIG_I2C_MUX
-
- Define this option if you have I2C devices reached over 1 .. n
- I2C Muxes like the pca9544a. This option addes a new I2C
- Command "i2c bus [muxtype:muxaddr:muxchannel]" which adds a
- new I2C Bus to the existing I2C Busses. If you select the
- new Bus with "i2c dev", u-bbot sends first the commandos for
- the muxes to activate this new "bus".
-
- CONFIG_I2C_MULTI_BUS must be also defined, to use this
- feature!
-
- Example:
- Adding a new I2C Bus reached over 2 pca9544a muxes
- The First mux with address 70 and channel 6
- The Second mux with address 71 and channel 4
-
- => i2c bus pca9544a:70:6:pca9544a:71:4
-
- Use the "i2c bus" command without parameter, to get a list
- of I2C Busses with muxes:
-
- => i2c bus
- Busses reached over muxes:
- Bus ID: 2
- reached over Mux(es):
- pca9544a@70 ch: 4
- Bus ID: 3
- reached over Mux(es):
- pca9544a@70 ch: 6
- pca9544a@71 ch: 4
- =>
-
- If you now switch to the new I2C Bus 3 with "i2c dev 3"
- u-boot first sends the command to the mux@70 to enable
- channel 6, and then the command to the mux@71 to enable
- the channel 4.
-
- After that, you can use the "normal" i2c commands as
- usual to communicate with your I2C devices behind
- the 2 muxes.
-
- This option is actually implemented for the bitbanging
- algorithm in common/soft_i2c.c and for the Hardware I2C
- Bus on the MPC8260. But it should be not so difficult
- to add this option to other architectures.
-
CONFIG_SOFT_I2C_READ_REPEATED_START
defining this will force the i2c_read() function in
Note: There is also a sha1sum command, which should perhaps
be deprecated in favour of 'hash sha1'.
+- Freescale i.MX specific commands:
+ CONFIG_CMD_HDMIDETECT
+ This enables 'hdmidet' command which returns true if an
+ HDMI monitor is detected. This command is i.MX 6 specific.
+
+ CONFIG_CMD_BMODE
+ This enables the 'bmode' (bootmode) command for forcing
+ a boot from specific media.
+
+ This is useful for forcing the ROM's usb downloader to
+ activate upon a watchdog reset which is nice when iterating
+ on U-Boot. Using the reset button or running bmode normal
+ will set it back to normal. This command currently
+ supports i.MX53 and i.MX6.
+
- Signing support:
CONFIG_RSA
Support for NAND boot using simple NAND drivers that
expose the cmd_ctrl() interface.
+ CONFIG_SPL_MPC8XXX_INIT_DDR_SUPPORT
+ Set for the SPL on PPC mpc8xxx targets, support for
+ arch/powerpc/cpu/mpc8xxx/ddr/libddr.o in SPL binary.
+
+ CONFIG_SPL_COMMON_INIT_DDR
+ Set for common ddr init with serial presence detect in
+ SPL binary.
+
CONFIG_SYS_NAND_5_ADDR_CYCLE, CONFIG_SYS_NAND_PAGE_COUNT,
CONFIG_SYS_NAND_PAGE_SIZE, CONFIG_SYS_NAND_OOBSIZE,
CONFIG_SYS_NAND_BLOCK_SIZE, CONFIG_SYS_NAND_BAD_BLOCK_POS,
option to re-enable it. This will affect the output of the
bootm command when booting a FIT image.
+- TPL framework
+ CONFIG_TPL
+ Enable building of TPL globally.
+
+ CONFIG_TPL_PAD_TO
+ Image offset to which the TPL should be padded before appending
+ the TPL payload. By default, this is defined as
+ CONFIG_SPL_MAX_SIZE, or 0 if CONFIG_SPL_MAX_SIZE is undefined.
+ CONFIG_SPL_PAD_TO must be either 0, meaning to append the SPL
+ payload without any padding, or >= CONFIG_SPL_MAX_SIZE.
+
Modem Support:
--------------
that is executed before the actual U-Boot. E.g. when
compiling a NAND SPL.
+- CONFIG_TPL_BUILD
+ Modifies the behaviour of start.S when compiling a loader
+ that is executed after the SPL and before the actual U-Boot.
+ It is loaded by the SPL.
+
- CONFIG_SYS_MPC85XX_NO_RESETVEC
Only for 85xx systems. If this variable is specified, the section
.resetvec is not kept and the section .bootpg is placed in the
npe_ucode - set load address for the NPE microcode
+ silent_linux - If set then linux will be told to boot silently, by
+ changing the console to be empty. If "yes" it will be
+ made silent. If "no" it will not be made silent. If
+ unset, then it will be made silent if the U-Boot console
+ is silent.
+
tftpsrcport - If this is set, the value is used for TFTP's
UDP source port.
