x86: Use CONFIG_CHROMEOS_VBOOT for verified boot
At present CONFIG_CHROMEOS is used to determine whether verified boot is
in use. The code to implement that is not in U-Boot mainline.
However, it is useful to be able to boot a Chromebook in developer mode
in U-Boot mainline without needing the verified boot code.
To allow this, use CONFIG_CHROMEOS_VBOOT to indicate that verified boot
should be used, and CONFIG_CHROMEOS to indicate that the board supports
Chrome OS. That allows us to define CONFIG_CHROMEOS on coral.

Also if the tables point to other tables (such as console log or a ramoops

commit 92765f45bb95 ("env: Access Environment in SPI flashes before

reason is, that env_init() sets the init bit, if there
is no init function defined in an environment driver,
and use default return value -ENOENT in this case
later for setting the default environment.
Change:
Environment driver can now implement an init
function and return, if this function does nothing,
simply -ENOENT.
env_init() now handles -ENOENT correct by setting the
inited bit for the environment driver. And if there
is no other environment driver whose init function
returns 0, load than the default environment.
This prevents that each environment driver needs to set the
default environment.

lib: Add getopt
Some commands can get very unweildy if they have too many positional
arguments. Adding options makes them easier to read, remember, and
understand.
This implementation of getopt has been taken from barebox, which has had
option support for quite a while. I have made a few modifications to their
version, such as the removal of opterr in favor of a separate getopt_silent
function. In addition, I have moved all global variables into struct
getopt_context.
The getopt from barebox also re-orders the arguments passed to it so that
non-options are placed last. This allows users to specify options anywhere.
For example, `ls -l foo/ -R` would be re-ordered to `ls -l -R foo/` as
getopt parsed the options. However, this feature conflicts with the const
argv in cmd_tbl->cmd. This was originally added in 54841ab50c ("Make sure
that argv[] argument pointers are not modified."). The reason stated in
that commit is that hush requires argv to stay unmodified. Has this
situation changed? Barebox also uses hush, and does not have this problem.
Perhaps we could use their fix?
I have assigned maintenance of getopt to Simon Glass, as it is currently
only used by the log command. I would also be fine maintaining it.

config video failed
rk_vop_probe() Device failed: ret=-110
The "config video failed" error also goes away when I disable higher
log levels, and it claims to have successfully probed the device.
