Stock kernel does not boot for me on that board:
ubi0: attaching mtd2
ubi0: scanning is finished
ubi0: attached mtd2 (name "mtd=0", size 53 MiB)
ubi0: PEB size: 131072 bytes (128 KiB), LEB size: 126976 bytes
ubi0: min./max. I/O unit sizes: 2048/2048, sub-page size 2048
ubi0: VID header offset: 2048 (aligned 2048), data offset: 4096
ubi0: good PEBs: 428, bad PEBs: 0, corrupted PEBs: 0
ubi0: user volume: 0, internal volumes: 1, max. volumes count: 128
ubi0: max/mean erase counter: 2/1, WL threshold: 4096, image sequence number: 0
ubi0: available PEBs: 384, total reserved PEBs: 44, PEBs reserved for bad PEB handling: 40
Read 0 bytes from volume kernel to 44000000
Volume kernel not found!
ubi0: detaching mtd2
ubi0: mtd2 is detached
But once I comment out the psci_set_osi_mode() call I can boot mainline
kernel. The tz_version node contains this:
CRM-TZ.WNS.5.1-00068
Do I need to update? Which TZ version works with mainline kernel?
Thanks,
baruch
