Hi,

I am testing marvell_cesa on a kirkwood device (QNAP TS-212p, Marvell
Kirkwood 88F6282, dts: http://pastebin.com/Gk95KFHf ).
As of kernel 4.4 (4.4.0-trunk-kirkwood #1 Debian 4.4-1~exp1) it fails
in the following way:

modprobe marvell_cesa allhwsupport=1
dmesg | tail -n 1
[ 1057.855091] marvell-cesa: probe of f1030000.crypto failed with error -12

or:

modprobe marvell_cesa
dmesg | tail -n 1
[ 9178.399357] marvell-cesa: probe of f1030000.crypto failed with error -524

With kernel 4.3 it would fail with error -22 on that hardware. There
are scattered reports from other users experiencing the same issue
(1,2,3)

I wonder if this is a result of an invalid definition of the
crypto-sram in the dts of this SoC, or perhaps some other problem
(PEBKAC included).

I can provide SSH access to the affected device if needed.

Best regards,
Jan
