From 9f444c351c735d3cb82bdd732ff276ce6100c56f Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Fri, 20 May 2016 10:48:44 -0500 Subject: soc/intel/apollolake: add support for writing logical boot partition 2 On apollolake the boot media layout is different in that the traditional "BIOS" region contains another data structure with the boot assets such as CSE firmware, PMC microcode, CPU microcode, and boot firmware to name a few. There's also a sort of recovery mechanism where there is a second data structure with similar contents halfway through the "BIOS" region. This second structure is referred as the logical boot partition 2 (LBP2), and it's optionally employed. Add support for writing the LBP2 to a specified FMAP region to accommodate platforms which require it.
