[U-Boot] new dev question

[David Nelson]

hello, i was wondering if anyone could direct me to some good resources to
get a new dev up to speed with the requirements/provisions that exist for
porting U-Boot to new boards. i am working solo building a distro from
scratch and it would be especially beneficial to have U-Boot as the primary
supported bootloader for my releases in the coming time.

thanks in advance,
David Nelson.
