> Synopsis: imxspi causes a kernel panic during boot on novena (armv7)
> Category: kernel arm
> Environment:
System : OpenBSD 6.9
Details : OpenBSD 6.9 (GENERIC) #386: Tue Apr 20 04:06:48 MDT 2021
[email protected]:/usr/src/sys/arch/armv7/compile/GENERIC
Architecture: OpenBSD.armv7
Machine : armv
> Description:
On the Novena bsd.rd boots and the install is successful but bsd fails to boot
due to a panic caused by imxpsi.
(Note: To be able to boot I had to create u-boot-dtb.img from stock u-boot
source.
The SPL in the dtb pkg looks for u-boot-dtb.img, not u-boot.img which is
supplied in the u-boot pkg, and fails to load load u-boot shell.)
