You mean the driver we maintain?

am using an AMD flash chip on my board. Which one of the drivers do I
load? How are these initialized?

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]).

appreciated.

Just ask :-)
