6574040b18 iPod Nano 2G LCD sleep: Powering down LDO2 also affects USB, so we can't do that to shut off the LCD. Leave it on for now, and use the lightweight approach for waking up the Leadis LCD.

386503502b Various Nano2g changes - enable the rest of crt0.S (including clock setup) and make the nano2g bootloader do something useful (displaying gpio ports). Also add checks for the fifo-full condition in the LCD driver - required after enabling all the crt0.S inits

afe43d3fcb Basic changes to add nano 2g to the build system, based on the Meizu M3 port. The bootloader builds, but does nothing due to lack of any drivers.
