My R-class and M-class setups continue to work with this series applied on
top of next-20170201 plus following fixup for PATCH 2/3

-#define VECTORS_BASE UL(0xffff0000)
-
- /*
- * We fix the TCM memories max 32 KiB ITCM resp DTCM at these
- * locations
+ #ifdef CONFIG_XIP_KERNEL
+ #define KERNEL_START _sdata
+ #else

FWIW: Tested-by: Vladimir Murzin <vladimir.murzin@xxxxxxx>

Thanks!
