[coreboot] [PATCH]clean up bootblocksize handling in cbfstool, kconfig

[Maciej Pijanka]

Hello

I feel somewhat guilty for this ROMBASE problem as i was on irc
bugging about inability to move bootblock in chip and rom layout for
me was looking like

0-64k cbfs
64-128k bootblock, then empty space, then jump code
and empty space was about 20k

so i asked how i could change that to move bootblock towards jumpcode
to make that empty space gap smaller.

While change done caused another problems with ROMBASE, i simply
changed ROMBASE to 4G - size of rom (hardcoded, i know that this can
be calculated depending on actual selected chip size), also i created
small change in linker script used to generate bootblock
which automatically makes gap small (assuming rounding to 256byte
boundaries etc)

I already posted this patch once, but maybe it was overlooked. That
already commited change plus this patch make me able to save about 20k
of raw flash space, and it boots (then later crash on lzma problem but
this is with or without moveing of bootblock)

best regards
Maciej
