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;
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:
make NAME_defconfig
where "NAME_defconfig" is the name of one of the existing configu-
