[coreboot] [PATCH] CBFS bounce buffer fix

[Myles Watson]

src/boot/selfboot.c: In function 'get_bounce_buffer':
src/boot/ssrc/boot/selfboot.c: In function 'get_bounce_buffer':
src/boot/selfboot.c:113: warning: declaration of 'bounce_size' shadows a
global elfboot.c:113: warning: declaration of 'bounce_size' shadows a global

The global never got initialized, so I couldn't boot a kernel.  Now I can,
but I'm not sure this is the most elegant fix, or even that it is 100%
correct.

While I was there I changed another bounce_size to size to avoid confusion
with the global, and made selfboot static to get rid of this warning:

src/boot/selfboot.c:508: warning: no previous prototype for 'selfboot'
