From 333b7209ed486f5a9cba2b9727edd6170fdace70 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Wed, 15 Jul 2015 02:53:45 +0200 Subject: Makefile: Add target for building bootable SPL image for SoCFPGA Add build target for generating boot partition images recognised by the SoCFPGA BootROM. The SoCFPGA BootROM expects four copies of the u-boot-spl-dtb.sfp at the beginning of boot partition. Those are u-boot-spl-dtb.bin augmented by a header with which the BootROM can work. The u-boot-dtb.img uImage is appended to this to produce a full boot partition image, the u-boot-with-spl-dtb.sfp . This is the name of the final target.
