CONFIG_E1000
Support for Intel 8254x gigabit chips.
+ CONFIG_E1000_FALLBACK_MAC
+ default MAC for empty eeprom after production.
+
CONFIG_EEPRO100
Support for Intel 82557/82559/82559ER chips.
Optional CONFIG_EEPRO100_SROM_WRITE enables eeprom
Define this to use i/o functions instead of macros
(some hardware wont work with macros)
+ CONFIG_DRIVER_SMC911X
+ Support for SMSC's LAN911x and LAN921x chips
+
+ CONFIG_DRIVER_SMC911X_BASE
+ Define this to hold the physical address
+ of the device (I/O space)
+
+ CONFIG_DRIVER_SMC911X_32_BIT
+ Define this if data bus is 32 bits
+
+ CONFIG_DRIVER_SMC911X_16_BIT
+ Define this if data bus is 16 bits. If your processor
+ automatically converts one 32 bit word to two 16 bit
+ words you may also try CONFIG_DRIVER_SMC911X_32_BIT.
+
- USB Support:
At the moment only the UHCI host controller is
supported (PIP405, MIP405, MPC5200); define
display); also select one of the supported displays
by defining one of these:
+ CONFIG_ATMEL_LCD:
+
+ HITACHI TX09D70VM1CCA, 3.5", 240x320.
+
CONFIG_NEC_NL6448AC33:
NEC NL6448AC33-18. Active, color, single scan.
Currently supported on some MPC8xxx processors. For an
example, see include/configs/mpc8349emds.h.
+ CONFIG_MXC_SPI
+
+ Enables the driver for the SPI controllers on i.MX and MXC
+ SoCs. Currently only i.MX31 is supported.
+
- FPGA Support: CONFIG_FPGA
Enables FPGA subsystem.
before giving up the operation. If not defined, a
default value of 5 is used.
+ CONFIG_ARP_TIMEOUT
+
+ Timeout waiting for an ARP reply in milliseconds.
+
- Command Interpreter:
CONFIG_AUTO_COMPLETE
Scratch address used by the alternate memory test
You only need to set this if address zero isn't writeable
+- CFG_MEM_TOP_HIDE (PPC only):
+ If CFG_MEM_TOP_HIDE is defined in the board config header,
+ this specified memory area will get subtracted from the top
+ (end) of ram and won't get "touched" at all by U-Boot. By
+ fixing up gd->ram_size the Linux kernel should gets passed
+ the now "corrected" memory size and won't touch it either.
+ This should work for arch/ppc and arch/powerpc. Only Linux
+ board ports in arch/powerpc with bootwrapper support that
+ recalculate the memory size from the SDRAM controller setup
+ will have to get fixed in Linux additionally.
+
+ This option can be used as a workaround for the 440EPx/GRx
+ CHIP 11 errata where the last 256 bytes in SDRAM shouldn't
+ be touched.
+
+ WARNING: Please make sure that this value is a multiple of
+ the Linux page size (normally 4k). If this is not the case,
+ then the end address of the Linux memory will be located at a
+ non page size aligned address and this could cause major
+ problems.
+
- CFG_TFTP_LOADADDR:
Default load address for network file downloads
- CFG_BOOTMAPSZ:
Maximum size of memory mapped by the startup code of
the Linux kernel; all data that must be processed by
- the Linux kernel (bd_info, boot arguments, eventually
- initrd image) must be put below this limit.
+ the Linux kernel (bd_info, boot arguments, FDT blob if
+ used) must be put below this limit, unless "bootm_low"
+ enviroment variable is defined and non-zero. In such case
+ all data for the Linux kernel must be between "bootm_low"
+ and "bootm_low" + CFG_BOOTMAPSZ.
- CFG_MAX_FLASH_BANKS:
Max number of Flash memory banks
This option also enables the building of the cfi_flash driver
in the drivers directory
+- CFG_FLASH_USE_BUFFER_WRITE
+ Use buffered writes to flash.
+
+- CONFIG_FLASH_SPANSION_S29WS_N
+ s29ws-n MirrorBit flash has non-standard addresses for buffered
+ write commands.
+
- CFG_FLASH_QUIET_TEST
If this option is defined, the common CFI flash doesn't
print it's warning upon not recognized FLASH banks. This
bootfile - Name of the image to load with TFTP
+ bootm_low - Memory range available for image processing in the bootm
+ command can be restricted. This variable is given as
+ a hexadecimal number and defines lowest address allowed
+ for use by the bootm command. See also "bootm_size"
+ environment variable. Address defined by "bootm_low" is
+ also the base of the initial memory mapping for the Linux
+ kernel -- see the descripton of CFG_BOOTMAPSZ.
+
+ bootm_size - Memory range available for image processing in the bootm
+ command can be restricted. This variable is given as
+ a hexadecimal number and defines the size of the region
+ allowed for use by the bootm command. See also "bootm_low"
+ environment variable.
