* Support for two new platforms based on ARC700
- Abilis TB10x SoC [Chritisian/Pierrick]
- Simulator only System-C Model [Mischa]
* ARC specific MM improvements
- Avoid full TLB flush (ASID increment) on munmap (even single page)
- VIPT Cache Flushing improvements
+ Delayed dcache flush for non-aliasing dcache (big performance boost)
+ icache flush aliasing agnostic (no need to kill all possible aliases)
* Others
- Avoid needless rebuild of DTB files for every kernel build
- Remove builtin cmdline as that is already provided by DeviceTree/bootargs
- Fixing unaligned access emulation corner case
- checkpatch fixes [Sachin]
- Various fixlets [Noam]
- Minor build failures/cleanups

There's no (Kconfig) macro CONFIG_BLOCK_DEV_RAM. (CONFIG_BLK_DEV_RAM
does exist though.) But linux/blk.h got killed in 2005 anyway (in a
patch titled "kill blk.h"), so these three lines can be removed.

This is minimal infrastructure needed for devicetree work.
It uses an a sample "skeleton" devicetree - embedded in kernel image -
to print the board, manufacturer by parsing the top-level "compatible"
string.
As of now we don't need any additional "board" specific "machine_desc".
TODO: support interpreting the command line as boot-loader passed dtb
