I tested following three devices with success:
Mikrotik RB532
Linksys WRT54GS v1.0
Microchip PIC32MZ Graphics (DA) Starter Kit

I have attached the dmesg output.

For Microchip I had to revert commit ec7c2a107a59a60079eff3308e791a3441231f2e.
It seems there is a Kconfig naming conflict.
I use:
CONFIG_BUILTIN_DTB_NAME="pic32mzda_sk"
CONFIG_BUILTIN_DTB=y
CONFIG_MIPS_NO_APPENDED_DTB=y

Furthermore I had to recognize that ethernet is not working in
Linux, just in u-boot. But that is unrelated to the patches.

You can add my 
Tested-by: Waldemar Brodkorb <wbx@openadk.org>
to the patch series.

best regards and thanks very much,
 Waldemar
