board: add support for ARC AXS101 and AXS103 Software Development Platforms
PATCH v2 1/1 board: add support for ARC AXS101 and AXS103 Software Development Platforms
The AXS10x Platform consists of a DesignWare AXC001 CPU
Card (with ARC 770D core) in case of AXS101 or AXC003 CPU Card (typically with ARC HS38 core) in case of AXS103 mounted on an ARC Software Development Platform Mainboard with DesignWare peripherals:
* SD/MMC contoller
* Gigabit network contoller
* Serial ports (8250-compatible)
* USB 2.0
* SPI
* I2C
It also houses HDMI output for external monitor connection.
For stand-alone usage of the board (with only keyboard, mouse and montor attached) kernel console and getty made available on tty0 as well as on serial port (ttyS3).
Note there're 2 prerequisites:
[1] u-boot: 2015.07 - fix creation of .config
http://patchwork.ozlabs.org/patch/502558/
[2] binutils: fix buildng of Linux kernel for ARCv2 ISA
http://patchwork.ozlabs.org/patch/503550/
---
Changes in v2:
[1] Clean-up of /etc/inittab so it matches Buildroot's default with only changes
a) addition of getty on tty0
b) use default serial console instead of hard-coded ttyS0
[2] Rework of defconfigs
a) Beautify congifs with comments and spaces between sections
b) Explicitly specify Linux kernel and headers versions so build results are reproducible.

Applied, thanks. For defconfigs, we generally like to have a readme.txt file in board/<something>/ that explains how to flash/use the generated system on the HW. But that's of course only if special instructions are needed.
Thanks!

Thanks for that.
I will send instructions shortly (probably in few days) because do have some things to mention on how to use that board with generated files.
Also note I mentioned another prerequisite:
----------->8----------
u-boot: 2015.07 - fix creation of .config
http://patchwork.ozlabs.org/patch/502558/
----------->8----------
without which snps_axs103_defconfig will fail to build U-Boot.
I'm wondering if you saw my recent comments for that patch, probably we may want to revisit it sometime soon.
