Hi, 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. Thanks!
