Aspeed AST2600 EVB
Introduction
============
The AST2600 EVB is an evaluation board for the AST2600 SoC, most
commonly used as a Server Management Processor. It includes a
Dual-core ARM Cortex A7 processor with DDR4 SDRAM (up to 2GB), SPI
flash memory devices for BMC and host firmwares and numerous
controllers to drive the server board.

How to build it
===============
Configure buildroot:
$ make aspeed_ast2600evb_defconfig
Compile everything and build the rootfs image:
$ make
Result of the build
===================
After building, the output/images directory contains:
output/images/
├── aspeed-ast2600-evb.dtb
├── flash.img
├── image.itb
├── rootfs.cpio
├── rootfs.cpio.xz
├── rootfs.tar
├── u-boot.bin
└── zImage
Flashing the image
==================
To update the contents of the first flash device, copy flash.img :
$ flashcp flash.img /dev/mtd0
or simply the boot loader:
$ flashcp u-boot.bin /dev/mtd1
Preparing the board
===================
* Connect a serial line to the board
* Power-up the board
Booting the board
=================
The AST2600 EVB boots from the SPI flash device directly and loads a
first bootloader (usually U-Boot). U-Boot will attempt to load a Linux
kernel from the same flash device by default but other storage could
be used.
* from U-Boot
The FIT image image.itb can be used to boot the board from U-Boot
using tftp
* with QEMU
