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.
