*	ps3flash: Cache the last accessed FLASH chunk	Geert Uytterhoeven	2009-06-15	1	-105/+104
\| \| \| \| \| \| \| \| \| \| \| \|	Add support for caching, to reduce FLASH wear when writing using small blocksizes. As we also don't care anymore about heads and tails in case of partial writes, this greatly simplifies the code for handling writes. Note: We don't bother caching reads smaller than the FLASH chunk size (256 KiB).

*	ps3: Replace direct file operations by callback	Geert Uytterhoeven	2009-06-15	1	-24/+70
\| \| \| \| \| \| \| \| \| \| \| \|	Currently the FLASH database is updated by the kernel using file operations, meant for userspace only. While this works for us because copy_{from,to}_user() on powerpc can handle kernel pointers, this is unportable and a bad example. Replace the file operations by callbacks, registered by the ps3flash driver.

*	ps3: FLASH ROM Storage Driver	Geert Uytterhoeven	2007-07-22	1	-0/+440
	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>
