One of the majore things needed on the BSP used to be lzma decompression which put a 16K array on the stack. We fixed this a while ago, bringing down stack usage on our Intel based boards to about 1K (and giving each core a 4K stack) We fixed the issue by putting that big array in the heap instead. Maybe we can fix the AMD code in the same way. I would like to see some actual stack usage data first though Stefan -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
