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.
