[U-Boot] [PATCH 0/20] tegra: Expand Nyan-big support

[Matthew Gorski]

I am porting u-boot to nyan_big and need some input.  I have been searching
high and low and found this thread here: [U-Boot] [PATCH 0/20] tegra:
Expand Nyan-big support

 https://lists.denx.de/pipermail/u-boot/2015-March/209530.html

I have tried to build u-boot with the branch here:

https://git.collabora.com/cgit/user/tomeu/u-boot.git/commit/?h=nyan-big

and also the official chromium next branch

I followed building instructions here: https://www.chromium.org
/chromium-os/firmware-porting-guide/using-nv-u-boot-on-the-
samsung-arm-chromebook

I build with these commands:

mkimage -e 0x81000100 -a 0x81000100 -f kernel-big.its kernel-u-boot

(with and without the load address setting)

vbutil_kernel --arch arm --pack kernel.bin --keyblock
/usr/share/vboot/devkeys/kernel.keyblock --signprivate
/usr/share/vboot/devkeys/kernel_data_key.vbprivk --version 1 --config
dummy.txt --vmlinuz kernel-u-boot --bootloader dummy.txt

I have had numerous failed attempts to boot uboot from sdcard mmcblk1p1

Any help is appreciated I have only gotten a blank screen after weeks of
flashing.  I can boot custom v3.10 kernels so I assume I am using the
correct building procedure.  Thanks in advance for help from the u-boot
community.
