Flash Driver

[Navin Boppuri]

Coool!! Now I have the flash driver registering itself and telling me
all about the number of partitions on my flash etc. etc. I have the
flash device in the /dev directory. Now, how do I use them? I remember
using them before using the dd command.

Thank you,
Navin.

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]).

Just ask :-)
