If GZIP Compression support is enabled, GZIP compressed U-Boot raw binary will be at a specified RAM location which is defined at UBOOT_COMPRESSED_BINARY_FIT_USER_DEF_ADDR and will be assign it as the source address.
gunzip function in spl_load_fit_image ,will decompress the GZIP compressed U-Boot raw binary which is placed at source address to the default CONFIG_SYS_TEXT_BASE location.
spl_load_fit_image function will load the decompressed U-Boot raw binary, which is placed at the CONFIG_SYS_TEXT_BASE location.
