AUTO_ZRELADDR config enables auto calculation of the decompressed kernel image address. AUTO_ZRELADDR config is mutually exclusive to ZBOOT_ROM, and also assumes zImage to be loaded in the first 128MiB from start of memory. CFT::Call For Testing Requesting maintainers of Realview platforms to evaluate the changes on the board and comment, as I dont have the board for testing, and also requesting an ACK.
