ps3: FLASH ROM Storage Driver
Add a FLASH ROM Storage Driver for the PS3: - Implemented as a misc character device driver - Uses a fixed 256 KiB buffer allocated from boot memory as the hypervisor requires the writing of aligned 256 KiB blocks Cc: Geoff Levand <geoffrey.levand@am.sony.com> Signed-off-by: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com> Cc: Jens Axboe <jens.axboe@oracle.com> Cc: James Bottomley <James.Bottomley@steeleye.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

+ Include support for the PS3 FLASH ROM Storage.
+
+ This support is required to access the PS3 FLASH ROM, which
+ contains the boot loader and some boot options.
+ In general, all users will say Y or M.

+ As this driver needs a fixed buffer of 256 KiB of memory, it can
+ be disabled on the kernel command line using "ps3flash=off", to
+ not allocate this fixed buffer.
