From 9dd6c43103f12ece08732fbc4661efc4b17b4d18 Mon Sep 17 00:00:00 2001 From: cshore Date: Sun, 28 Nov 2010 22:04:40 +0000 Subject: [PATCH] bcm63xx: Add board id override fixup. Add a fixup for the kernel to check the bcm tag of the image for a boardid in the information1 field, and use that instead of the supplied one by cfe. This is triggered by a + at the start of the information1 field. Also modify the image generation to generate apropriately tagged images.
