npcx: correct the image copies indication bits for npcx9
In npcx5/7, we use two reserved bits in the BSC1 register (offset 0x07 of the MDC register) to indicate what the current image copy is. In npcx9, these two bits are used by the booter. We need to change them to another two empty scratch bits which are not used by the booter. BUG=b:165777478 BRANCH=none TEST=pass "make buildall" TEST=check the related bits changed by "sysump ro" and "sysjump rw" Signed-off-by: Jun Lin <CHLin56@nuvoton.com> Change-Id: I6bcfe6d8752c6fa10022a21956d2e0ceb7f9418e Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/ec/+/3153119 Tested-by: CH Lin <chlin56@nuvoton.com> Reviewed-by: caveh jalali <caveh@chromium.org> Auto-Submit: CH Lin <chlin56@nuvoton.com> Commit-Queue: caveh jalali <caveh@chromium.org>
