tegra: colibri_t30: initial Toradex Colibri T30 L4T R16 support
Tested on early prototype Colibri T30 V1.0a eMMC module.
Known issues:
- spurious boot hang after following kernel message
[ 5.595219] Timed out waiting for lock bit on pll pll_a
- no audio (SGTL5000) support integrated yet
- NAND detection/support disabled for now due to boot hang
- USB OTG support disabled for now due to boot hang
- trying to spawn L4T R16 X driver seems to hang
Note: requires uImage with adjusted entry point/load address as follows
mkimage -A arm -C none -O linux -T kernel -a 0x82008000 -e 0x82008000 -n 'Linux-3.1.10-colibri_t30' -d zImage uImage
