Make spl_*_load_image() functions return a value instead of
hanging if a problem is encountered. This enables main spl code
to make the decision whether to hang or not, thus preparing
it to support alternative boot devices.
Some boot devices (namely nand and spi) do not hang on error.
Instead, they return normally and SPL proceeds to boot the
contents of the load address. This is considered a bug and
is rectified by hanging on error for these devices as well.

Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute. It refers to

Make the support for 4K subpage I/O on a SPI NOR flash configurable.
A board which requires the SPI NOR to be accessed in larger 32KiB
or 64KiB pages can disable the 4K subpage support, but by default,
the support for 4K subpage I/O is enabled. The functionality of this
option is the same as CONFIG_MTD_SPI_NOR_USE_4K_SECTORS in Linux.
This is extremely useful in case one uses UBI on a SPI NOR flash.
UBI needs at least 15k EBs and can not work on a flash which uses
4k ones, so disabling the support for 4k subpages lets UBI work on
such flash.
