Add a small utility for displaying some information about U-Boot and the
hardware it's running on in a similar fashion to the popular neofetch
tool for Linux [1].
While the output is meant to be useful, it should also be pleasing to
look at and perhaps entertaining. The ufetch command aims to bring this
to U-Boot, featuring a colorful ASCII art version of the U-Boot logo.

Why waste an output line on something that does not exist. Get rid of the loop!

Who cares about the number of commands if the one he needs is not provided.
This information is not helpful.

:3 relates to what in U-Boot?
No clue, why you consider the cat command the relevant one, needing special mention.

Neither full control nor VMs are provided by U-Boot.

The use case was outlined in v1 and maybe missed in v2. This is a "toy"
utility, like 2048, to make it easier to show off things like "I just
made U-Boot work on this new platform". So yes, it's going to bloat the
code size, but it's also not going to be enabled in production (or
hopefully, defconfigs when submitted for new boards...).

The point is to do something like that.

This patch failed to build on ARM 32-bit boards. Looks like
current_el() is only available on ARM64, as defined in
arch/arm/include/asm/system.h.
Build log:
/usr/src/u-boot-master/cmd/ufetch.c:166: undefined reference to `current_el'
All the best,
Tony
