[PULL REQUEST] boot and linker script stuff

[Nicolas Pitre]

Russell, please pull the following:

  http://git.linaro.org/people/nicolas.pitre/linux xip_zdata

This contains important fixes to the XIP linker script, some more linker 
script cleanups, .bss clearing and .data copying speedups related to the 
above, and an opt-in config option for XIP kernels that allows for 
compressing .data in ROM that depend on those other patches to work 
properly.

This is the same patches as the series titled "[PATCH v2 0/5] make XIP 
kernel .data compressed in ROM" plus some ACKs and Tested-bys.

The diffstat against v4.13-rc4 is:
