You mean the driver we maintain?

For AMD chips, configure:
CONFIG_FLASH=y
CONFIG_AMD_FLASH=y
Add a "partition" scheme for your board to "drivers/char/flash_config.c";
see the comment in this file.
There is no more configuration needed (assuming you are booting from
PPCBoot, which will pass the necessary parameters to the Linux kernel
[physical start address and size of the flash memory]).
