Flash Driver

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,

You mean the driver we maintain?

For AMD chips, configure:


Add a "partition" scheme for your board to
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]).
