From 5cfd583c5c2d803dd240768ec343b5a95f42c785 Mon Sep 17 00:00:00 2001 From: Christoph Grenz Date: Sun, 18 Sep 2011 22:54:51 +0200 Subject: [PATCH] console: support integrated 7-segment displays for POST codes Add a configuration option POST_PORT which defaults to 0x80 and can be redefined by boards which have integrated POST displays on another I/O port. Change post.c to output POST codes to this port instead of 0x80 hardcoded.
