FIT header verification in mkimage was treating a return code as a boolean,
which meant that failures in validating the fit were seen as successes.
Additionally, mkimage was checking all formats to find a header which
passes validation, rather than using the image type specified to

The usual SPI transmission protocol in Allwinner A10 and A31

Add CLK support to enable AHB and MOD SPI clocks on sun4i_spi driver.
Clock disablement could be done while releasing the bus transfer, but

So to make a proper clock handling, the clocks should enable it in claim

To drain rx fifo the fifo need to poll for how much data has

To achieve this, the current code is using wait_for_bit logic

With current order of include files, the file designware_spi.c
can't see that the struct global_data has the member
board_type when CONFIG_BOARD_TYPES is defined. By not seeing this
then all the members are shifted in the struct global_data.
So when the driver is trying to read from device tree blob, it
would pass the wrong address to the function 'fdtdev_get_int'.
This will make to use the default frequency 500000.
The fix consists of changing the order of include files in
