From dfac3ffd07f5a99b1605aec5a6b24f389a1a8827 Mon Sep 17 00:00:00 2001 From: Luis Araneda Date: Sun, 13 May 2018 14:05:38 -0400 Subject: [PATCH] zynq: reworked image creation process After commit a1248da (zynq: convert to new image build code), all boards, became unbootable, entering into a boot loop. Replace the compressed kernel zImage by an uncompressed Image, which is compressed after with gzip. Also, enable the creation of an initramfs image by default. Change images' filename to match the compatible string from the respective .dts file (_). Also, use the shared mkits.sh script and remove the target specific one.
