[coreboot] [v2] r4148 - trunk/coreboot-v2/src/config

[svn at coreboot.org]

Author: hailfinger

New Revision: 4148

Added:
   trunk/coreboot-v2/src/config/failovercalculation.lb
   trunk/coreboot-v2/src/config/nofailovercalculation.lb
Log:
Somehow svn add didn't work for the include files. Commit the remainder
of r4147.

Thanks to Myles' patch adding support for include statements,
refactoring Config.lb became possible.

Factor out ROM size calculation from Config.lb.
  
This patch converts 87 boards (with and without USE_FAILOVER_IMAGE),
but it has to work around a parser bug. 

89 files changed, 209 insertions(+), 2415 deletions(-)
A total of 2206 removed lines.
  
Abuild works for all changed boards on khepri.

Myles writes:
I've tested serengeti for the failover portion and s2892 for the
nofailover portion.  ldoptions are exactly the same and they both boot
the same.
