There's still a lot on my todo list regarding this, but it
should help people get things going.

Next week I'm hoping to get an image for the Toshiba AC100
put together.

At some point I need to build some kernel rpms and some scripts
to automate building the images.

It also just occurred to me that the image probably won't work
on something other than the Peach Pi (13" Chromebook 2) because
a different u-boot needs to be built for other machines. I'll
have to do something about that, but they are all supported by
mainline u-boot. :-(

You will need at least a 4GB uSD card.

1) Put Chromebook into dev mode
2) Put the above image on a uSD card (4GB minimum)
3) Press Ctrl-U to boot off the uSD card
4) Interrupt u-boot. You will need to reset your u-boot variables
manually. Do the following:

setenv baudrate 115200
setenv bootargs_common 'console=tty1'
setenv bootargs_init 'setenv bootargs ${bootargs_common}
${bootargs_rootfs} ${bootargs_extra}'
setenv bootargs_rootfs 'root=/dev/mmcblk1p3 zfsroot=exynos/ROOT'
setenv bootcmd 'run bootargs_init; root bootdev_init; run
kernel_init'
setenv bootdelay 3
setenv bootdev 'mmc 1:4'
setenv bootdev_init 'mmc rescan; mmc dev 1'
setenv dtb dtb
setenv kernel zImage
setenv kernel_init 'ext2load ${bootdev} ${loadaddr_kernel}
${kernel}; ext2load {$bootdev} ${loadaddr_dtb} ${dtb}; bootz
${loadaddr_kernel} - ${loadaddr_dtb}'
setenv loadaddr_dtb 0x23000000
setenv loadaddr_kernel 0x22000000
setenv stderr lcd
setenv stdin cros-ec-keyb
setenv stdout lcd

saveenv
reset

5) Press Ctrl+U on every boot boot RSEL off the uSD card instead of
ChromeOS off the internal eMMC.

For Peach Pit or Snow Chromebooks you should only need to change the
dtb on the boot partition:
