1b96da67a0 chromium: Update docs to clone vboot_reference directly
We don't need a full checkout of Chrome OS to build U-Boot with
Chromium OS verified boot. Update the instructions accordingly and fix a
typo which joins the output directory and defconfig.

9d73e85a87 cros: Expand the Chromium OS documentation
The current documentation only covers how to chain-load U-Boot on a
Chromebook. Add more information about the other ways to use U-Boot on
Chromebooks.

In particular it is again possible to build it with Chromium OS
verified boot.

84996795c2 tegra: nyan-big: Update CONFIG_SYS_TEXT to the default in README.chromium
To build U-Boot on a Nyan Big Chromebook the docs outline adjusting the Tegra124
defined CONFIG_SYS_TEXT_BASE but this has since been moved to individual config
files. We should have the default required for U-Boot chain loading on the
chromebook as the default CONFIG_SYS_TEXT_BASE and update the docs to remove
this now non required step.

c9af6673e8 README: Add instructions for chain-loading U-Boot
Most Chromebooks support chain-loading U-Boot but instructions are
somewhat scattered. Add a README to hold this information within the
U-Boot tree. Also add the standard developer keys to simplify the
instructions, since they are small.

For now this only supports nyan-big.
