From 69ea83c3c57a99b9f853c128b5596c649eb73969 Mon Sep 17 00:00:00 2001 From: Zheng Bao Date: Sun, 22 Jan 2023 21:08:18 +0800 Subject: [PATCH] amdfwtool: Change .rom.efs to .rom and .rom to .rom.body To support 32M flash, the non-vboot also need to split amdfw. The amdfw.rom is the default filename added to CBFS. Keep the default filename and then we don't have to change all the CBFS definition. This is one of series of patches to support 32/64M flash.
