From 6095cd1501143025c51a6505fd37c4e2614f0347 Mon Sep 17 00:00:00 2001 From: Zheng Bao Date: Tue, 21 Feb 2023 10:52:47 +0800 Subject: amdfwtool: Clean up the logic sequence of pointer growing When the EFS data is being packed, the pointer should be at EFS header. After that, it should be at body location.
