Hey, such foreword spoils good talk, so i'll try to be short.

from nand'. All with 10 lines in config file. Just noone need it.

Cause is that this stuff is not good :)

Process of changing configuration is not development. Process of looking
up something in C sources of Qi is development ;)

with minimalism, let us all use the bootloader that is standard, smart,
configurable and well supported.
I think easiest way is to use fw_setenv. I rethought, need relatively
trivial modification to u-boot to support loading plain file to env
variable with something like 'ext2loadvar location [var]'. But this
brain-dead by design idea require bootloader to support all possible
fses (how does qi reads ubifs for kernel parameters, if it has no
support for ubi?)

It's impossible to offend me with good arguments.
