[v2] r4252 - trunk/coreboot-v2/src/cpu/amd/car

Author: ruik
Date: 2009-05-04 21:26:43 +0200 (Mon, 04 May 2009)
New Revision: 4252

Modified:
   trunk/coreboot-v2/src/cpu/amd/car/clear_init_ram.c
Log:
The rev 4099 broke ECC boards, they need to have tidy the ECC tags. Myles reverted this change.
I think we can return the 4099 back under HAVE_ACPI_RESUME define to make everyone happy (and booting ;).
