flashrom v0.9.9-91 (Announce)

Hi,
my friend Ruik patched new version of flashrom to compile under DOS/DJGPP 2.05
http://flashrom.org/DOS
I tested it on my SPI HW and onboard flash.
He also found a bug in djgpp valloc() that returns NULL for larger block while malloc() works. Older DJGPP libc 2.04 doesn't suffer by this bug. It was already reported on DJGPP forum and even there's a patch applied in Arch Linux DJGPP crosscompiler package but we are missing djdev-205 binary patched package...

I recompiled current DJDEV 2.05 from CVS that contains fixed valloc() - it seems to work. Download here.

Just for curiosity: what is the difference between malloc and valloc?

valloc ensures the allocated block is page-aligned. It's needed e.g. for some buffers where HW has such limitation that buffer must start on aligned address. Flashrom/libpci use valloc. Valloc was OK in DJDEV 2.04 and then was broken in 2.05, later fixed in CVS-only.
