Hello,

I'm adding Romain Perier in Cc, since he is actively working on the
CESA driver.

My Armada 385 -device hangs when using marvell-cesa -driver.
I'm using Linux 4.4.10 and armada-385-db-ap.dts.
I have also tried with the driver version of Linux 4.7-rc3.

Please see https://bugzilla.kernel.org/show_bug.cgi?id=120111 for details.

I just tested the marvell-cesa with Linux 4.8-rc2 and Armada 385.
There is still the same hanging issue (originally described on
https://bugzilla.kernel.org/show_bug.cgi?id=120111).

Please let me ask which model of Armada board has been verified to work with the
marvell-cesa driver?

The Armada 388 GP board.

For now:
The Armada 388-DB-GP
The Armada 385-DB-AP
The Armada 375-DB

I'm using a custom board based on 88F6820. Is this SoC
model fully supported by the driver? Do you know if there is some necessary
hardware initializations which must be done on u-boot? I'm using latest Marvell
patch set (2015_T1.0p16) on u-boot.

My test case have been:
# cryptsetup benchmark --cipher aes-cbc

and that always freezes the board.

Romain, can you test the same scenario, and see if you can reproduce
the hang or not?

Sure,


I have did exactly the same tests with Linux 4.8-rc2 (using a rootfs 
buildroot-2016.02 over nfs) on A388-db-gp and A385-db-ap, both work just 
fine. I launched the benchmark several times.

I am running uboot, Marvell version: 2015_T1.0p5
