FW: Zlib compress

[Steve Tsai]

I replace zlib.c and I can read the file now. 
I only replace datum = *(__u16*)buf with datum =
get_unaligned((__u16*)buf) in cfi_amdstd_write funtion. Is is enough? I
read the discussion about alignment trap and mtd in armlinux mail list,
and it seems that I should modify more codes.

I'm not aware of any related to JFFS2 or MTD other than the ones in the 
flash driver. Did you decode the oops you got? Where was it from?
