From f88204e02b2ece82a76544070f37a4e2e2bd0f11 Mon Sep 17 00:00:00 2001 From: Alexandru Gagniuc Date: Fri, 3 Aug 2012 13:20:57 -0500 Subject: Add a capability for mainboard-specific posting. Some mainboards have really nice capabilities for posting, beyond simple POST cards. Further, some can not use a POST card. This change defines a weak symbol (mainboard_post) that can be overridden by a real mainboard_post function. If, for example, you'd like to do something fancy before the payload starts, you can add this to mainboard.c: void mainboard_post(u8 value) { switch(value){ case POST_TIME_TO_PARTY: some_fancy_lights(); break; } } Maybe the post function should be an entry in the device. We're beginning to over-use weak symbols. BUG=None TEST=Build and boot a google chromebook. Observe that it still works. Use it to drive some pretty lights.
