From 32ab283b1086ef53fadcd4be92df6e41c5d06438 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Tue, 11 Jun 2013 16:36:37 -0500 Subject: cpu: Add CPU microcode file to cbfs with 16-byte alignment On x86 there is a 16-byte alignment requirement for the addresses containing the CPU microcode. The cbfs files containing the microcode are used in memory-mapped fashion when loading new mircocode. Therefore, the data payload's address/offset of a cbfs file in flash dictates the resulting alignment. Fix this by processing the CPU microcode cbfs file separately as it uses $(CBFSTOOL) to find the proper location within the provided rom image.
