From 3167fb70f8366d8698383679b4fbcfaa643e9d2e Mon Sep 17 00:00:00 2001 From: Karthikeyan Ramasubramanian Date: Mon, 16 Oct 2023 14:53:57 -0600 Subject: soc/amd/*: Set AMD_FW_AB_POSITION to either 64 or 128 bytes When CBFS verification is enabled, add amdfw_a/b.rom at offset 128 bytes to account for CBFS file header with hash attribute. When CBFS verification is disabled, add amdfw_a/b.rom at offset 64 bytes to account for CBFS file header without hash attribute. BUG=None TEST=Build Skyrim, Myst BIOS images with and without CBFS verification enabled.
