From 104058ede714d3d84f27025a7b5467c6bb137ffd Mon Sep 17 00:00:00 2001 From: Vineet Gupta Date: Fri, 22 Mar 2013 22:04:27 +0530 Subject: ARC: [build] Allow uncompressed uImage The existing uImage target always generates gzip compressed image which drags bootup for some very slow FPGA customer boards. So introduce seperate make targets:uImage.{bin,gz} with uncompressed being default. Also tie gz generation to CONFIG_KERNEL_GZIP, which a platform can select in it's Kconfig if it wishes gz to be default.
