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@....com>

Thanks!
