[PATCH]Implement per chipset rom enable sequence framework, and enable Fam10 build with Kconfig

[Patrick Georgi]

Hi,

attached patch implements a framework to do rom enable sequences for the
tinybootblock system and implements the rom enable for Fam10.

Changes:
- Pass BIST through the bootblock (AMD wants this)
- Rework walkcbfs to leave two registers unused, so BIST doesn't break
romcc on non-mmx/sse systems
- Provide enable_rom code for Fam10 northbridge and AMD8111 southbridge
and hook it up in amd/serengeti_cheetah_fam10

Build tested on amd/serengeti_cheetah_fam10 and emulation/qemu-x86. QEmu
is also boot-tested, the AMD board failed in my last tests. As I'm out
of ideas on what might be wrong in Fam10 init, I decided to publish it -
it's an improvement over what we have now, right? ;-)

Updated patches after feedback from Stefan:

20091230-2-romcc-ignore-unused-includes:
(was already in the older patch): make romcc define __PRE_RAM__

romcc doesn't like #ifdef'd out #include statements that are bogus, like:
#ifdef FOO
#include FOO
#endif FOO
It complains about the "#include " line if FOO is undefined, and in the
older patch I worked around it.
Make romcc ignore #include lines that shouldn't be loaded anyway.

20091230-3-amdfam10-should-not-work-in-topdir:
$(CURDIR) in Kconfig is always the top level directory. use $(obj) instead.

20091230-4-kconfig-enable_rom-and-fam10
All the other stuff from the original patch, changed to make use of the
fixed #include behaviour (eliminates a file, and two config variables).

Build tested with qemu and serengeti_cheetah_fam10.
