The u-boot 'bootargs' env overwrites the one from chosen ?

I just tested and U-Boot 'bootargs' has precedence over DT bootargs
but I didn't find a way to append boot parameters from U-Boot. You can
either overwrite it completely or not.

Yes. That seems to be the current case.
Perhaps we can merge
ARM_ATAG_DTB_COMPAT_CMDLINE_FROM_BOOTLOADER
and CMDLINE_EXTEND in one generic config stating
the desired bootargs behavior.

Does this sound sane?

Hi Ezequiel,

You could enable ARM_ATAG_DTB_COMPAT_CMDLINE_FROM_BOOTLOADER on
omap2plus_defconfig but just having a sane DTB bootargs default value
is better IMHO.

Best regards,
Javier
