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.
