[U-Boot] [PATCH v2 0/7] ARC updates

[Alexey Brodkin]

This patchset is meant to prepare ARC for device model utilization.
The most important things done:

 [1] Separation of interrupt vectore tables from start.S
 [2] Merge of low-level start-up code (written in assembly) for ARCompat and
     ARCv2 architectures
 [3] Separation of interrupt and exception handling code in a separate source
     file (ints_low.S)
 [4] Major clean-up of start-up code and switch to heavy use of routines written
     in C (re-use implementations for x86 in board_f.c)

Changes in v2:
 * Always build invalidate_icache_all() and invalidate_dcache_all()
 * Unconditionally disable caches on early start, if required enable them later
   in init_cache_f_r()
 * Fixed typo in commit message

Alexey Brodkin (7):
  arc: cache - build invalidate_icache_all() and invalidate_dcache_all()
        always
  arc: merge common start-up code between ARC and ARCv2
  arc: move low-level interrupt and exception handlers in a separate
    file
  arc: clean-up init procedure
  arc: re-generate defconfigs
  arc: get rid of CONFIG_SYS_GENERIC_GLOBAL_DATA
  arc: minor fixes in Kconfig
