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)
Alexey Brodkin (6): 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: get rid of CONFIG_SYS_GENERIC_GLOBAL_DATA arc: minor fixes in Kconfig arc: re-generate defconfigs
