I'm having difficulties with the new enable_partno the cape manager fails
to load my dtbo even through the "echo slots" works just fine. I have:
$ cat /boot/uboot/uEnv.txt
optargs=fixrtc capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN
capemgr.enable_partno=BB-UART4-RTS
uenvcmd=i2c mw 0x24 1 0x3e
loadfdt=load mmc ${bootpart} ${fdtaddr} ${bootdir}/dtbs/${fdtfile}
and at boot time the cape manager says:
# dmesg | grep capemgr
[ 0.000000] Kernel command line: console=ttyO0,115200n8 fixrtc
capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN
