[PATCH 0/5] ARM: initial support for RC Module UEMD SoCs and MB 77.07 board

[Antony Pavlov]

Research Centre "Module" (RC Module) is
a Russian development company designing
mixed-signal ASICs and real-time video-image
processing systems.

К1879ХБ1Я (AKA K1879HB1YA) is a UEMD family SoC that combines
a DSP core based on the NeuroMatrix(r) family
with an ARM architecture CPU ARM1176JZF-S core.

The MB 77.07 is a small (80x80 mm) single-board computer
developed in Russia by the RC Module.
It was developed as an educational board for К1879ХБ1Я SoC
capabilities demonstration.

See http://www.module.ru/en/catalog/micro/micro_pc/ for details.

MB 77.07 barebox HOWTO
======================

0. Download barebox sources and build barebox.bin image

    $ git clone -b next.mb7707.20140416 https://github.com/frantony/barebox barebox.mb7707
    $ cd barebox.mb7707
    $ export ARCH=arm
    $ export CROSS_COMPILE=<your_ARM_toolchain_prefix>
         e.g. export CROSS_COMPILE=/opt/arm-2013.11/bin/arm-none-linux-gnueabi-
    $ make module-mb7707_defconfig
    $ make

You will get the 'barebox.bin' file.


1. burn MBOOT bootloader to the board's ROM;


2. Barebox can be started from MBOOT using tftp.
You have to setup tftp-server on host 192.168.0.1.
Put your barebox.bin to tftp-server directory
(usual /tftpboot or /srv/tftp).

Connect your MB 77.07 board to your tftp-server network via
Ethernet RJ45 connector on the board.

Connect to К1879ХБ1Я's UART (use "SERIAL" connector on the booard)
using your favorite terminal program.


3. turn on the board, press any key in you terminal program
to stop autoboot and load barebox.bin image to the board's RAM:

    MBOOT # set bootfile barebox.bin
    MBOOT # tftpboot
    greth: greth_halt
    TFTP Using GRETH_10/100 device
    TFTP params: server 192.168.0.1 our_ip 192.168.0.7
    TFTP params: filename 'barebox.bin' load_address 0x40100000
    TFTP Loading: ##########################
    TFTP done
    greth: greth_halt
    MBOOT #


4. run barebox

    MBOOT # go 0x40100000

unreachable is for marking positions in the code which are unreachable
but the compiler does not know it. reset_cpu() *is* reachable, so
unreachable is wrong here. How about just calling hang() here?

I'll resend the series next week. I'll try to add usb support this weekend.

I have some other almost ready series in my queue:

* digic series (digic support is in qemu-2.0 now);
* switch dir-320 to device tree;
* mips cache + ELF-kexec;
* pci.
