Now digging into it.
Okay, small update, booting u-boot v2020.07 an 5.8.x-rc7 no dice… Looking around i found this bug report:
https://community.nxp.com/thread/460616
We need to figure out what’s missing for PSCI support…
it’s enabled in u-boot:
u-boot$ cat .config| grep PSCI
CONFIG_ARCH_SUPPORT_PSCI=y
CONFIG_ARMV7_PSCI=y
CONFIG_ARMV7_PSCI_NR_CPUS=4
