If LZMA Compression support is enabled, LZMA compressed U-Boot
binary will be placed at a specified RAM location which is
defined at CONFIG_SYS_LOAD_ADDR and will be assigned  as the
source address.

image_decomp() function, will decompress the LZMA compressed
U-Boot binary which is placed at source address(CONFIG_SYS_LOAD_ADDR)
to the default CONFIG_SYS_TEXT_BASE location.

spl_load_fit_image function will load the decompressed U-Boot
binary, which is placed at the CONFIG_SYS_TEXT_BASE location.
