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
