Subject: [PATCH 0/3] crypto: inside-secure: Add Support for MaxLinear Platform


I have been utilizing inside-secure driver on MaxLinear
SoC platform (which has eip197 hardware inside).

One issue I found is that I needed to flip the endianness
in eip197_write_firmware() function, which for reason I am
not aware is using big-endian.
The firmware that I have is clearly using little-endian,
and unfortunately I do not have access to Marvell platform
to do more investigation or comparison there.
I have also tried to look for clues in Inside-Secure's
hardware/firmware documentation, without success.

Thus, assuming each vendor may use different endian format,
on these patch set I add support for little-endian firmware
(default remains big-endian). MaxLinear platform can then
utilize the option, which is implemented as soc data.

An alternative to this would be implementing the option
as a new device-tree property, but for now I assume we do
not need that since each platform endianness should be
fixed, and will not vary per board/hardware.

Please help review.
