Andes Technology SoC AE350
===========================

AE350 is the mainline SoC produced by Andes Technology using AX25 CPU core
base on RISC-V architecture.

AE350 has integrated both AHB and APB bus and many periphals for application
and product development.

AX25-AE350
=========

AX25-AE350 is the SoC with AE350 hardcore CPU.

Configurations
==============

CONFIG_SKIP_LOWLEVEL_INIT:
	If you want to boot this system from SPI ROM and bypass e-bios (the
	other boot loader on ROM). You should undefine CONFIG_SKIP_LOWLEVEL_INIT
	in "include/configs/ax25-ae350.h".

Build and boot steps
====================

build:
1. Prepare the toolchains and make sure the $PATH to toolchains is correct.
2. Use `make ax25-ae350_defconfig` in u-boot root to build the image.

Verification
====================

Target
====================
1. startup
2. relocation
3. timer driver
4. uart driver
5. mac driver
6. mmc driver
7. spi driver

Steps
====================
1. Define CONFIG_SKIP_LOWLEVEL_INIT to build u-boot which is loaded via gdb from ram.
2. Undefine CONFIG_SKIP_LOWLEVEL_INIT to build u-boot which is booted from spi rom.
3. Ping a server by mac driver
4. Scan sd card and copy u-boot image which is booted from flash to ram by sd driver.
5. Burn this u-boot image to spi rom by spi driver
6. Re-boot u-boot from spi flash with power off and power on.
