Add support for disabling subpage write support via
CONFIG_SYS_NAND_NO_SUBPAGE_WRITE.

Currently the Linux Arasan driver does not support subpage writes and in
case of running UBI and accessing the same UBI volume from both U-Boot
and Linux it is required to have the same subpage write configuration
else the location of the UBI headers (EC + VID) will be misaligned
(subpage vs page) and incompatible. Hence the need for disabling
subpage write support in the U-Boot Arasan NAND driver.

The VCU disable bit(8) in IP disable register of efuse
is valid only if PL powered up and hence PL powerup status
has to be considered while determining the CG part also.
This patch considers the PL powerup status and ignores the VCU
disable bit if PL not powered up.
This fixes the issue of "unknown" id for CG parts if PL not powered up
and VCU bit(8) is not set.

Various minor sandbox improvements
Better buildman warning handling
Misc other things

It is useful to obtain the block-protect setting of the SPI flash, so we
know whether it is fully open or (perhaps partially) write-protected. Add
a method for this. Update the sandbox driver to process this operation and
add a test.
Signed-off-by: NSimon Glass <sjg@chromium.org>

The current test is a functional test, covering all the way from the
command line to the sandbox SPI driver. This is useful, but it is easier
to diagnose failures with a smaller test.

Add a simple test which reads and writes data and checks that it is stored
and retrieved correctly.

At present these functions return 0 on success. For some devices we want

It is useful to be able to invert the colours in some cases so that the

It is strange that function takes a private data structure from another

function internally work out how to find its required information.
