From d22650afabd6ce0003569f11b1605a69aac0f22c Mon Sep 17 00:00:00 2001 From: Allen Martin Date: Thu, 19 Apr 2012 07:58:57 +0000 Subject: mkconfig: add support for SPL CPU Add support for specifying a differnt CPU for main u-boot and SPL u-boot builds. This is done by adding an optional SPL CPU after the main CPU in boards.cfg as follows: normal_cpu:spl_cpu This this case CPU will be set to "normal_cpu" during the main u-boot build and "spl_cpu" during the SPL build.
