ipq806x: fix AP148 boot from NOR This patch allows AP148 to boot from NOR flash. As we're using a FIT image as kernel (which includes kernel bin + DTB) we enable the MTD_SPLIT_FIT_FW kernel option, which will detect the FIT image and automatically split the "firmware" partition into 2 MTD parts (kernel + rootfs). The rootfs will then be parsed and split between rootfs + rootfs_data, as usual. Signed-off-by: Mathieu Olivari <mathieu@codeaurora.org> SVN-Revision: 44794

ipq806x: switch AP148 to using SMEM based MTD parser *Enable SMEM MTD parser and its dependencies (SMEM & HW spinlocks) in the kernel config *Replaces the MTD layout in DT by the dynamic layout provided by the SMEM parser for AP148 Using the OF based parser is still possible on platforms which have a fixed MTD partition layout.
