[U-Boot] Patch to enable LEDs on sunxi/Cubietruck

[Prof. Dr. Gundolf Kiefer]

Dear developers,

the attached patch adds LED support for the Cubietruck board.

I found that the support for the onboard leds is missing for
sunxi-based boards in the latest Debian unstable and perhaps
upstream version of U-Boot. IMHO LEDs are very helpful for headless
systems. Perhaps the patch can be helpful somehow.

The code has basically been ported from the U-Boot version maintained at
linux-sunxi.org. As in the sunxi version, the blue led is switched on
by default.

Kind regards,

Gundolf Kiefer

Thanks for the patches!

If you could submit these patches to u-boot upstream, that would be
best; we're trying to minimize the patches that are not already included
upstream.


live well,
