From 4defe4559e86e26545ab2f542656a4b966dcde53 Mon Sep 17 00:00:00 2001 From: James Hogan Date: Fri, 30 Aug 2013 16:42:42 +0100 Subject: MIPS: Add uImage build target Add a uImage build target for MIPS, which builds uImage.gz (a U-Boot image of vmlinux.bin.gz), and then symlinks it to uImage. This allows for the use of other compression algorithms in future, and is how a few other architectures do it. It's enabled conditionally on load-y >= 0xffffffff80000000 which hopefully allows 64bit kernels to also work as long as the load and entry address can be represented by the 32bit addresses in the U-Boot image format.
