Subject: spl: spi: Consolidate spi_load_image_os into spl_spi_load_image
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=14509a28aa20808875cc934eaf62f439345e6db6;p=u-boot.git

spl: spi: Consolidate spi_load_image_os into spl_spi_load_image

spi_load_image_os performs almost the same steps as the non-falcon-boot
path of spl_spi_load_image. The load address is different, and it also
loads a device tree, but that's it. Refactor the boot process so that
they can both use the same load function.
