[Thomas: drop post-image script copying the gdbinit file, and suggest
to use gdb -x option instead to point to the gdbinit file in board/.]

C-SKY Development Kit
Intro
=====
C-SKY is a CPU Architecture from www.c-sky.com and has it own instruction set.
Just like arm and mips in linux/arch, it named as 'csky'.
gx6605s develop board is made by Hangzhou Nationalchip and C-SKY.
Hardware Spec:
* CPU: ck610 up to 594Mhz
* Integrate with 64MB ddr2 in SOC.
* Integrate with hardware Jtag.
* Integrate with usb-to-serial chip.
* USB ehci controller in SOC.
* Power Supply: DC 5V from two micro-usb.
How to build it
===============
Configure Buildroot
-------------------
The csky_gx6605s_defconfig configuration is a sample configuration with
all that is required to bring the gx6605s Development Board:
$ make csky_gx6605s_defconfig
Build everything
----------------
Note: you will need to have access to the network, since Buildroot will
download the packages' sources.
$ make
Result of the build
-------------------
After building, you should obtain this tree:
output/images/
├── vmlinux
├── rootfs.ext2
└── <board name>.dtb
How to run it
=============
Prepare Jtag-Server
-------------------
Download the Jtag-Server here:
https://github.com/c-sky/tools/raw/master/DebugServerConsole-linux-x86_64-V4.2.00-20161213.tar.gz
Go to the unpacked directory:
$./DebugServerConsole -ddc -rstwait 1000 -prereset -port 1025
Perhaps you need to use "sudo", which need libusb to detect c510:b210
$ sudo ./DebugServerConsole -ddc -rstwait 1000 -prereset -port 1025
Prepare USB drive
-----------------
You sould determine which device associated to the usb drive
carefully. eg:
$ cat /proc/partitions
8 48 1971712 sdd
8 49 976720 sdd1
$ sudo dd if=rootfs.ext2 of=/dev/sdd1
$ sudo sync
Run
---
Plug the usb drive on gx6605s dev board.
Setup the Console with the rate 115200/8-N-1.
$ ./output/host/usr/bin/csky-linux-gdb -x board/csky/gx6605s/gdbinit output/images/vmlinux
