r659 - in coreboot-v3: arch/x86/geodelx northbridge/amd/geodelx

Author: hailfinger

New Revision: 659

Modified:
   coreboot-v3/arch/x86/geodelx/geodelx.c
   coreboot-v3/northbridge/amd/geodelx/raminit.c
Log:
northbridge/amd/geodelx/raminit.c:auto_size_dimm() checks for the
mathematically impossible condition of a value being above and below the
specified range at the same time. Change it to check for out-of-range.
arch/x86/geodelx/geodelx.c:set_delay_control() is missing a break, it
will keep going and mess up DRAM timings.

Both changes look right to me.

The raminit in v2 was fixed in r2899 | rminnich | 2007-10-26 with this
log:
