-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 ae350_rv[32|64]_defconfig` in u-boot root to build the image for 32 or 64 bit.
-
-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.
