From e1ecfc93af4918c2a9a4647cf550cb7ecc2b92d6 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Wed, 16 Sep 2015 15:18:04 -0500 Subject: intel: update common and FSP cache-as-ram parameters Instead of just passing bits, tsc_low, tsc_high, and an opaque pointer to chipset context those fields are bundled into a cache_as_ram_params struct. Additionally, a new struct fsp_car_context is created to hold the FSP information. These could be combined as the existing romstage code assumes what the chipset_context values are, but I'm leaving the concept of "common" alone for the time being. While working in that area the ABI between assembly and C code has changed to just pass a single pointer to cache_as_ram_params struct. Lastly, validate the bootloader cache-as-ram region with the Kconfig options. BUG=chrome-os-partner:44676 BRANCH=None TEST=Built and booted glados.
