Cool stuff, great work! I've a number of comments, I will reply
to the individual patches with those.

I've tried to get this to run on my own h8_homlet_v2 but
unfortunately I cannot get it to work. My own board does
boot into some chinese top-set-box environment when booting
without a sdcard and connected to a tv. But it does not show
any output on the uart connector at the bottom right of the
board (I've tried with 2 different adapters, including the
one from the Merrii A80 board which has the exact same connector
on the board).

Not having an uart also means that I cannot get the board into
FEL mode (I do have a usb A <-> A cable).

I wonder if my board has a broken uart, or if the system
image uses a different uart by default ?

Have you tried booting with u-boot written to sdcard with
this patch-set ? Does this work, and does the SPL header
get printend on the bottom right uart connector ?

Regards,

Hans
