Hi Tom,
I Try to running Linux Mainline Kernel V 4.4.0 to boot up in my chromebook using Ctrl+U in dev mode and using USBv3.0 drive as a drive.
I using this command:
aperfeito at alarm:/# sudo make -j5 uImage UIMAGE_LOADADDR=0x82408000 dtbs modules
In doc in http://git.denx.de/?p=u-boot.git;a=blob_plain;f=doc/README.chromium;hb=HEAD
SAY:
1. Patch U-Boot
Open include/configs/tegra124-common.h
Change:
#define CONFIG_SYS_TEXT_BASE 0x80110000
to:
#define CONFIG_SYS_TEXT_BASE 0x81000100
I did this and compiled U-boot.... OK
And after copy the files generated by Kernel compilation (uImage) Mychromebooks BLEPS everytime when try to boot with this files generated:
vbutil_kernel \
--pack vmlinux.kpart \
--version 1 \
--vmlinuz vmlinux.uimg \
--arch arm \
--keyblock /usr/share/vboot/devkeys/kernel.keyblock \
--signprivate /usr/share/vboot/devkeys/kernel_data_key.vbprivk \
--config config.txt \ # console=tty0 init=/sbin/init root=PARTUUID=%U/PARTNROFF=1 rootwait rw noinitrd
--bootloader bootloader.bin #dummy
file vmlinux.kpart created
Put the file vmlinux.kpart in Kernel Partition /dev/sda6 and file uImage compiled in /boot also dtb(s) tegra124-nyan-big and -blaze.dtbs
My USB:
aperfeito at alarm ~]$ sudo cgpt show /dev/sda

Sorry, Alexander. I’m not sure what you are asking me to do here.
I’ve got an action-item to look at Simon’s Nyan-big patches, but haven’t had a chance to do that this week. I’ll try to get to it early next week, and if everything looks good I’ll post a PR to bring those patches in to u-boot/tegra.
Hope this helps,
Tom

There is a series which shows how to do this for tegra and rockchip.
It is at u-boot-dm/chain-working and you can find a README there as
well.
The series has not been applied yet - I think it is in Tom Warren's queue?

Simon
