ARM based boards:
-----------------
Possible values are:
CFG_8260ADS - original MPC8260ADS
CFG_8266ADS - MPC8266ADS (untested)
- CFG_PQ2FADS - PQ2FADS-ZU
+ CFG_PQ2FADS - PQ2FADS-ZU or PQ2FADS-VR
- MPC824X Family Member (if CONFIG_MPC824X is defined)
- Define exactly one of
- CONFIG_MPC8240, CONFIG_MPC8245
+ Define exactly one of
+ CONFIG_MPC8240, CONFIG_MPC8245
- 8xx CPU Options: (if using an 8xx cpu)
Define one or more of
- CONFIG_8xx_GCLK_FREQ - if get_gclk_freq() can not work e.g.
- no 32KHz reference PIT/RTC clock
+ CONFIG_8xx_GCLK_FREQ - if get_gclk_freq() cannot work
+ e.g. if there is no 32KHz
+ reference PIT/RTC clock
-- Clock Interface:
+- Linux Kernel Interface:
CONFIG_CLOCKS_IN_MHZ
U-Boot stores all clock information in Hz
"clocks_in_mhz" can be defined so that U-Boot
converts clock data to MHZ before passing it to the
Linux kernel.
-
When CONFIG_CLOCKS_IN_MHZ is defined, a definition of
"clocks_in_mhz=1" is automatically included in the
default environment.
+ CONFIG_MEMSIZE_IN_BYTES [relevant for MIPS only]
+
+ When transfering memsize parameter to linux, some versions
+ expect it to be in bytes, others in MB.
+ Define CONFIG_MEMSIZE_IN_BYTES to make it in bytes.
+
- Console Interface:
Depending on board, define exactly one serial port
(like CONFIG_8xx_CONS_SMC1, CONFIG_8xx_CONS_SMC2,
default i/o. Serial console can be forced with
environment 'console=serial'.
+ When CONFIG_SILENT_CONSOLE is defined, all console
+ messages (by U-Boot and Linux!) can be silenced with
+ the "silent" environment variable. See
+ doc/README.silent for more information.

CFG_BAUDRATE_TABLE, see below.

CONFIG_HAS_DATAFLASH
Defining this option enables DataFlash features and
allows to read/write in Dataflash via the standard
commands cp, md...

+- Show boot progress:
CONFIG_SHOW_BOOT_PROGRESS
Defining this option allows to add some board-
-1 common/cmd_ide.c Read Error on boot device
-1 common/cmd_ide.c Image header has bad magic number
- -1 common/cmd_nvedit.c Environment not changable, but has bad CRC

Modem Support:
Enables debugging stuff (char screen[1024], dbg())
for modem support. Useful only with BDI2000.
+- Interrupt support (PPC):
+
+ There are common interrupt_init() and timer_interrupt()
+ for all PPC archs. interrupt_init() calls interrupt_init_cpu()
+ for cpu specific initialization. interrupt_init_cpu()
+ should set decrementer_count to appropriate value. If
+ cpu resets decrementer automatically after interrupt
+ (ppc4xx) it should set decrementer_count to zero.
+ timer_interrupt() calls timer_interrupt_cpu() for cpu
+ specific handling. If board has watchdog / status_led
+ / other_activity_monitor it works automatically from
+ general timer_interrupt().

Default load address for network file downloads
The size in bytes of the EEPROM device.
+- CFG_ENV_IS_IN_DATAFLASH:
+
+ Define this if you have a DataFlash memory device which you
+ want to use for the environment.
+
+ - CFG_ENV_OFFSET:
+ - CFG_ENV_ADDR:
+ - CFG_ENV_SIZE:
+
+ These three #defines specify the offset and size of the
+ environment area within the total memory of your DataFlash placed
+ at the specified address.
+
+
- CFG_SPI_INIT_OFFSET
Defines offset to the initial SPI buffer area in DPRAM. The
the default environment is used; a new CRC is computed as soon as you
use the "saveenv" command to store a valid environment.
+- CFG_FAULT_ECHO_LINK_DOWN:
+ Echo the inverted Ethernet link state to the fault LED.
+
+ Note: If this option is active, then CFG_FAULT_MII_ADDR
+ also needs to be defined.
