CONFIG_TULIP
Support for Digital 2114x chips.
- Optional CONFIG_TULIP_SELECT_MEDIA for board specific
- modem chip initialisation (KS8761/QS6611).
CONFIG_NATSEMI
Support for National dp83815 chips.
- activate this driver with CONFIG_SYS_I2C_RCAR
- This driver adds 4 i2c buses
- - CONFIG_SYS_RCAR_I2C0_BASE for setting the register channel 0
- - CONFIG_SYS_RCAR_I2C0_SPEED for for the speed channel 0
- - CONFIG_SYS_RCAR_I2C1_BASE for setting the register channel 1
- - CONFIG_SYS_RCAR_I2C1_SPEED for for the speed channel 1
- - CONFIG_SYS_RCAR_I2C2_BASE for setting the register channel 2
- - CONFIG_SYS_RCAR_I2C2_SPEED for for the speed channel 2
- - CONFIG_SYS_RCAR_I2C3_BASE for setting the register channel 3
- - CONFIG_SYS_RCAR_I2C3_SPEED for for the speed channel 3
- - CONFIF_SYS_RCAR_I2C_NUM_CONTROLLERS for number of i2c buses
-
- drivers/i2c/sh_i2c.c:
- activate this driver with CONFIG_SYS_I2C_SH
- This driver adds from 2 to 5 i2c buses
Configuration Settings:
-----------------------
-- CONFIG_SYS_SUPPORT_64BIT_DATA: Defined automatically if compiled as 64-bit.
+- MEM_SUPPORT_64BIT_DATA: Defined automatically if compiled as 64-bit.
Optionally it can be defined to support 64-bit memory commands.
- CONFIG_SYS_LONGHELP: Defined when you want long help messages included;
- CONFIG_SYS_BAUDRATE_TABLE:
List of legal baudrate settings for this board.
-- CONFIG_SYS_MEMTEST_START, CONFIG_SYS_MEMTEST_END:
- Begin and End addresses of the area used by the
- simple memory test.
-
-- CONFIG_SYS_MEMTEST_SCRATCH:
- Scratch address used by the alternate memory test
- You only need to set this if address zero isn't writeable
-
- CONFIG_SYS_MEM_RESERVE_SECURE
Only implemented for ARMv8 for now.
If defined, the size of CONFIG_SYS_MEM_RESERVE_SECURE memory
regular expression. This allows multiple variables to define the same
flags without explicitly listing them for each variable.
-- CONFIG_ENV_ACCESS_IGNORE_FORCE
- If defined, don't allow the -f switch to env set override variable
- access flags.
-
The following definitions that deal with the placement and management
of environment data (variable area); in general, we support the
following configurations:
If this macro is defined, then CONFIG_SYS_CCSRBAR_PHYS will be
forced to a value that ensures that CCSR is not relocated.
-- Floppy Disk Support:
- CONFIG_SYS_FDC_DRIVE_NUMBER
-
- the default drive number (default value 0)
-
- CONFIG_SYS_ISA_IO_STRIDE
-
- defines the spacing between FDC chipset registers
- (default value 1)
-
- CONFIG_SYS_ISA_IO_OFFSET
-
- defines the offset of register from address. It
- depends on which part of the data bus is connected to
- the FDC chipset. (default value 0)
-
- If CONFIG_SYS_ISA_IO_STRIDE CONFIG_SYS_ISA_IO_OFFSET and
- CONFIG_SYS_FDC_DRIVE_NUMBER are undefined, they take their
- default value.
-
- if CONFIG_SYS_FDC_HW_INIT is defined, then the function
- fdc_hw_init() is called at the beginning of the FDC
- setup. fdc_hw_init() must be provided by the board
- source code. It is used to make hardware-dependent
- initializations.
-
- CONFIG_IDE_AHB:
Most IDE controllers were designed to be connected with PCI
interface. Only few of them were designed for AHB interface.
Add the "loopw" memory command. This only takes effect if
the memory commands are activated globally (CONFIG_CMD_MEMORY).
-- CONFIG_MX_CYCLIC
+- CONFIG_CMD_MX_CYCLIC
Add the "mdc" and "mwc" memory commands. These are cyclic
"md/mw" commands.
Examples:
$ CROSS_COMPILE=ppc_4xx-
$ export CROSS_COMPILE
-Note: If you wish to generate Windows versions of the utilities in
- the tools directory you can use the MinGW toolchain
- (http://www.mingw.org). Set your HOST tools to the MinGW
- toolchain and execute 'make tools'. For example:
-
- $ make HOSTCC=i586-mingw32msvc-gcc HOSTSTRIP=i586-mingw32msvc-strip tools
-
- Binaries such as tools/mkimage.exe will be created which can
- be executed on computers running Windows.
-
U-Boot is intended to be simple to build. After installing the
sources you must configure U-Boot for one specific board type. This
is done by typing:
make NAME_defconfig
where "NAME_defconfig" is the name of one of the existing configu-
-rations; see boards.cfg for supported names.
+rations; see configs/*_defconfig for supported names.

+Note: for some boards special configuration names may exist; check if
additional information is available from the board vendor; for
instance, the TQM823L systems are available without (standard)
