Main reason for this patches is ability to use bootmenu
on devices that use lcd driver (like Toshiba AC100).
Lcd driver doesn't have ansi support while cfb_console does.
Ansi related code was moved from cfb_console to separate place.
Then this code was used in both cfb_console and lcd driver.
There are other duplicated code between cfb_console and lcd.
I'm not very experienced with video subsystem. Maybe there is a
better/more proper way to add ansi support for Toshiba AC100.

common: add ansi console base implementation
video: cfb_console: use common ansi implementation
lcd: use ansi console
paz00: enable bootmenu

This code is based on ansi implementation in cfb_console.
It is adopted to be used in lcd and cfb_console drivers.

Some explanation of what these new options do might be nice; the
features/benefits they enable.
Are any of the options generally useful? If so, should they be enabled
in tegra-common*.h?
You also didn't Cc Tom Warren (Tegra maintainer) so he likely won't see
the emails and hence won't apply this patch.

Thanks for the reply Stephen! I will add Tom Warren to Cc next time.
Bootmenu allows to create user friendly menu to choose different boot
options. For example next 3 lines in boot config
---
setenv bootmenu_0 "Boot kernel = setenv bootargs ..."
setenv bootmenu_1 "Boot recovery = setenv bootargs ..."
bootmenu 20
---
will generate bootmenu with 3 options:
---
*** U-Boot Boot Menu ***
Boot kernel
Boot recovery
U-Boot console
Press UP/DOWN to move, ENTER to select
---
More information about bootmenu is available at doc/README.bootmenu
I was focused on console part for this RFC. This patch is for testing
purposes. I will use tegra config instead of paz00 next time to allow
other users of tegra devices to try changes.

OK. Might it be better to use an extlinux.conf file? It already has
support for displaying a menu for all the options in the file, and
allowing the user to select which to boot. (Although I suspect the
extlinux.conf menu could be prettied up some). I suppose your example
above are more than just selecting which kernel to boot though, so
perhaps extlinux.conf wouldn't work.

I think you have the right idea. As you pointed out, there's a lot of
duplication between lcd code and video code which should be eliminated,
and this is a step in that direction.
Hannes Petermaier is currently also working on lcd console functionality
(Introduce lcd_console rotation), and I recommend that you sync with his
patches (V2 has just been posted).

This seems buggy. Not only does this limit us to one tab, it can potentially move the cursor
backwards. The LCD version of COL += 8 seems more correct.
