The issue you're seeing is due to a combination of commits
5f3bca0db8ac01a7
("ARM: shmobile: apmu: Add APMU DT support via Enable method") and
dc378795156d980c ("ARM: dts: r8a7790: Add APMU nodes").
When debug mode is enabled (SW8-4 = OFF), trying to boot secondary CPUs
may
lock up the system after a cold boot, depending of boot load version.
Hence
we explicitly prohibit that. BTW, this has been the case on Koelsch
since
commit
277efd30cfc72ec2 ("ARM: shmobile: Check r8a7791 MD21 at SMP boot").
Now, does series "[PATCH/RFT 0/4] ARM: shmobile: R-Car Gen2: Allow
booting
secondary CPU cores in debug mode" (included in all renesas-drivers
releases
during September) fix it for you?
Thanks for your series patches.
I have had some problems of receiving post mail from Linux-Renesas
Mailing
List recently.
Could you please forward these series patches to me?
They're included in renesas-drivers.
You can also get them from gitweb at
https://git.kernel.org/cgit/linux/kernel/git/geert/renesas-drivers.git/log/?h=topic/rcar-secondary-booting-in-debug-mode-v1
Thanks, I'll confirm these patches on my board.
Have you tried this series on your Lager? If yes, can I add your Tested-by?
Sorry for the late reply!.
I have totally forgotten my reporting test result to you.
I have tested this series on my Lager board. The bug has been fixed.
Which ES version of R-Car H1 do you have? If you don't know, you can
tell me the result of "md.l 0xff000044 1" in U-Boot.
My board information:
LAGER SPI_LOADER V0.28 2014.09.29
DEVICE S25FL512
U-Boot 2016.01 (Jul 27 2016 - 15:27:42 +0900)
CPU: Renesas Electronics R8A7790 rev 2.0
