From 086536ac84fcc9350802c09166f600becd52a1f8 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Thu, 14 May 2015 14:31:09 +0200 Subject: kernel: Pull uImage generation into separate class Pull the uImage image format generation from kernel.bbclass into a separate kernel-uimage.bbclass. Introduce new KERNEL_CLASSES variable, which allows registration of additional classes which implement new kernel image types. The default value of is to register kernel-uimage to preserve the original behavior.
