From 94aebe6cc3111c7c9e3cd1311cc9793d01cc3ded Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Thu, 5 Jan 2012 11:19:50 +0100 Subject: [PATCH] Makefile: Add u-boot.spr build target (SPEAr) On x600 (SPEAr600) U-Boot is appended to U-Boot SPL. Both images are created using mkimage (crc etc), so that the ROM bootloader can check its integrity. Padding needs to be done to the SPL image (with mkimage header) and not the binary. Otherwise the resulting image which is loaded/copied by the ROM bootloader to SRAM doesn't fit. The resulting image containing both U-Boot images is called u-boot.spr.
