Hi,
I have observed a possible regression in next-20151022
due to c074fef5d36e ("of/platform: Defer probes of registered devices").
The problem manifests on the r8a7791 based koelsch board.
With the above patch present booting the board using the shmobile_defconfig
results in no console output. While after reverting the above patch
the boot proceeds all the way to user-space.
With DEBUG_LL and EARLY_PRINTK enabled I was able to capture some console
output. I have included both that boot log, and a log of boot all the way to
userspace with the patch in question reverted.
The problem does not seem to manifiest on other boards for other
Renesas ARM SoCs that I have access too. In particular the
r8a7790 based lager board; the r8a7790 and r8a7791 are both members
of the R-Car Gen2 family of SoCs.
Boot fail to boot to userspace:
