From 3e3fef39e71ed0426130b36aa00e4630ebb537ae Mon Sep 17 00:00:00 2001 From: Frank Hunleth Date: Sat, 18 Apr 2015 16:27:42 -0400 Subject: [PATCH] uboot: add support for patch files and URLs The existing u-boot patch option only allowed directories to be specified. This adds support for URLs using similar code as found in linux/linux.mk. Local files are also handled now. This change is useful for Intel Edison support, so that Intel's u-boot patch can be downloaded rather than stored in the Buildroot source tree.
