U-Boot on Nyan
==============
Nyan-big is supported by mainline U-Boot. This device is based on Tegra124.
To build it, use the nyan-big config.
To boot it, connect a USB A-A cable from your computer to the back USB port.
Connect a servo board. Then with t20_rec and warn_rst held down:
sudo tegrarcm --bct cbootimage-configs/tegra124/nvidia/norrin/PM370_Hynix_2GB_H5TC4G63AFR_PBA_924MHz_01212014.bct
--bootloader u-boot-dtb-tegra.bin --loadaddr 0x80108000
The norrin config is close enough that it works well with Nyan.
