From a0d6cd4f492541290bfbe22092cead7ab7babdbf Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Sun, 15 Sep 2013 17:03:29 +0000 Subject: [PATCH] kernel/3.10: add new Kconfig option for firmware partition split Add a new kernel config option for generic firmware partition split support and change the uImage split support to depend on the new option. Aslo rename the MTD_UIMAGE_SPLIT_NAME option to MTD_SPLIT_FIRMWARE_NAME to make it more generic. The patch is in preparation for multiple firmware format support.
