New Revision: 4217

Modified:
   trunk/coreboot-v2/src/cpu/amd/car/clear_init_ram.c
Log:
Revert 4099 patch that causes an ECC error.  Memory has to be written while ECC
error checking is disabled.  The purpose of the patch was to preserve memory
used by ACPI resume code.  One possible solution is to read that memory and
write it back while ECC error-checking is disabled.
