the following patch was just integrated into master: commit 4d7d25f38abac4bcd3ea88a50b5f529f1e9ddb44 Author: Martin Roth martin.roth@se-eng.com Date: Fri Jul 25 14:39:05 2014 -0600
payloads/external/SeaBIOS: Allow setting buffers below 0xC0000
Add the option to coreboot to set the SeaBIOS buffers below 0xC0000. This is a requirement on the Intel Rangeley processor because it is designed so that only the processor can write the higher memory areas. This prevents USB and SATA from bus-mastering into the buffers when they're set in the typical 0xE0000 area.
This will be set to Y unless defaulted to N by the mainboard or chipset.
Push the SeaBIOS buffers down to 0x90000 segment for Mohon Peak
