I do also experience the boot problem described by Geert.

Head being:
b0625afe305253d0831af9289b37c906c18a781b
ARM: OMAP2+: Drop legacy platform data for am3 mpuss

=> BBB boots Ok.

Head being:
5a230524f87926f24d637fe62fd689f7f86f5036
ARM: dts: Use simple-pm-bus for genpd for am3 l4_wkup

=> BBB boot fails. (I don't have any debug parameters => last thing I
see in UART is from uBoot:

Bytes transferred = 89849 (15ef9 hex)
Kernel image @ 0x81000000 [ 0x000000 - 0x928200 ]
## Flattened Device Tree blob at 82000000
   Booting using the fdt blob at 0x82000000
   Using Device Tree in place at 82000000, end 82018ef8

Starting kernel ...

Head being 

5a230524f87926f24d637fe62fd689f7f86f5036 + this patch 
ARM: dts: Use simple-pm-bus for genpd for am3 l4_wkup (+ patch)
Boot still fails for me.

Please note - my environment takes the intermediate build result file:
arch/arm/boot/dts/.am335x-boneblack.dtb.dts.tmp

and compiles this with '-@' to allow further overlays.

Best Regards
