Creating a panic_write() for the common flash interface driver

[Rick Ramstetter]

Hi all,

I would like to use the mtdoops module to record kernel panics.
Unfortunately, the common flash interface driver doesn't define a
panic_write() function in struct mtd_info. Thus, the mtdoops driver is
unable to write to flash from kernel panic context.

Has anyone attempted to (or successfully) implemented such a
panic_write() function for AMD compatible (cfi_cmdset_0002.c) CFI
chips before? Care to share any relevant pointers or potential
pitfalls?

If there is a more appropriate mailing list to ask this question on,
please share relevant information about.

Thank you,
--Rick.
