Merge git://git.denx.de/u-boot-arc
In this patch-set we add support of new AXS103 firmware as well as
troubleshoot unexpected execution by multiple cores simultaneously.

axs103: Support slave core kick-start on axs103 v1.1 firmware
In axs103 v1.1 procedure to kick-start slave cores has changed quite a bit
compared t previous implementation.
In particular:
* We used to have a generic START bit for all cores selected by CORE_SEL
mask. But now we don't touch CORE_SEL at all because we have a dedicated
START bit for each core:
bit 0: Core 0 (master)
bit 1: Core 1 (slave)
* Now there's no need to select "manual" mode of core start
Additional challenge for us is how to tell which axs103 firmware we're
dealing with. For now we'll rely on ARC core version which was bumped
from 2.1c to 3.0.

axs103: Clean-up smp_kick_all_cpus()
* Rely on default pulse polarity value
* Don't mess with "multicore" value as it doesn't affect execution
In essence we now do a bare minimal stuff:
1) Select HS38x2_1 with CORE_SEL=1 bits
2) Select "manual" core start (via CREG) with START_MODE=0
3) Generate cpu_start pulse with START=1

arc: Rename AXS101 board to more generic AXS10x
As of now we have 2 flavors of ARC SDP boards:
1) AXS101 - with ARC770 in ASIC
2) AXS103 - with ARC HS38 in FPGA
Both options share exactly the same base-board and only differ with
CPU-tiles in use. That means all peripherals are the same (they are
implemented in FPGA on the base-board) and so generic board could be
used for both.
While at it:
* Recreated defconfigs with savedefconfig
* In include/configs/axs10x.h numerical sizes replaced with
defines from linux/sizes.h for better readability.
