Patch set updated for coreboot: soc/intel/apollolake: Add support for memory-mapped boot media
by Andrey Petrov 02 Mar '16

02 Mar '16

Andrey Petrov (andrey.petrov(a)intel.com) just uploaded a new patch set to gerrit, which you can find at https://review.coreboot.org/13706 -gerrit commit 37406b4f791ed44d2f117a96d7ebcc95dac50ec5 Author: Andrey Petrov <andrey.petrov(a)intel.com> Date: Fri Feb 12 15:12:43 2016 -0800 soc/intel/apollolake: Add support for memory-mapped boot media On Apollo Lake SPI flash is memory mapped. The mapping is different to previous platforms. Only "BIOS" region is mapped in contrast to whole flash. Also, the 128 KiB right below 4 GiB are being decoded by readonly SRAM. Fail accesses to those regions, rather than returning false data.
