From 5672dcd58c0ae7f7a0d14af0a88ff9c534e0936a Mon Sep 17 00:00:00 2001 From: Andrey Petrov Date: Fri, 12 Feb 2016 15:12:43 -0800 Subject: 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.
