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".

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.
