From be9533aba957e9c43f77381f436906951c13c98b Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Sat, 12 Oct 2019 14:35:25 +0200 Subject: nb/intel/gm45: Add C_ENVIRONMENT_BOOTBLOCK support The i82801ix_early_init is now called both in the bootblock and romstage. The rationale behind setting this up twice is to ensure bootblock-romstage compatibility in the future if for instance VBOOT is used. This moves the console init to the bootblock. The romstage now runs uncached. Adding a prog_run hooks to set up an MTRR to cache the romstage will be done in a followup patch. The default size of 64KiB is not modified for the bootblock as trying to fit both EHCI and SPI flash debugging needs a more space and 64KiB is the next power of 2 size that fits it. TESTED on Thinkpad X200.
