Hi,
I have quite a few patches queued up in the next branch of u-boot-dm,
ready for when the merge window options.
If anyone has time and can give it a spin on their board, it would be

appreciated!
On Jetson TK1, there's something up with USB.

Seaboard/Springbank appears to have the same issue. Additionally, the
flashing process spews a ton of:
ERROR: v7_dcache_inval_range - start address is not aligned - 0x3f77a428
ERROR: v7_dcache_inval_range - stop address is not aligned - 0x3f77ac28
Both of those bisect to:
7bf0b2d00982 dm: usb: tegra: Move to driver model for USB
I wonder if the NAND issue is just a bug that's triggered by stack/data
layout changes, and that commit tickles it?
For testing, it may be easier to load U-Boot into RAM that flash it
every time. If so, since there's only 1 USB port, you'll need to use
"usb reset" to re-scan that USB port. That will only work with the
following patch, which I'll send in a minute:
