With xip booting configuration, we don't need to copy the next image (U-Boot or linux xipimage) from flash to sdram area.
Flash memory organization is like this: spl-U-Boot: u-boot-spl.bin : 0x0800_0000 U-Boot : u-boot-dtb.bin : 0x0800_8000 linux : xipImage : 0x0800_8000
It is also possible to have U-Boot binary & linux binaries configured at different addresses of flash memory like U-Boot at 0x0800_8000 & linux xipImage at 0x0800_4000. But in any case, spl-U-Boot needs to be compiled for U-Boot as next binary with SPL_OS_BOOT option disabled. By default, spl is configured to boot linux xipImage.
