Subject: [PATCH 01/12] drm/ast: Fix AST2400 POST failure without BMC FW or VBIOS

From: "Y.C. Chen" <yc_chen at aspeedtech.com>

The current POST code for the AST2300/2400 family doesn't work properly if the chip hasn't been initialized previously by either the BMC own FW or the VBIOS. This fixes it.
