This patch does not enable AUTO_ZRELADDR by default. It forces AUTO_ZRELADDR to be enabled to be used unless ZBOOT_ROM is enabled.
I'm not opposed to this approach but I think the changelog is misleading.
AUTO_ZRELADDR is known to work on the Genmai, Koelsch, KZM9D and Lager boards and is enabled in their defconfigs.
I will defer to Magnus on weather he is comfortable with being enable globally for shmobile but if not perhaps it could be selected on a per-board or per-SoC basis.

This patch enables AUTO_ZRELADDR as default config to Renasas R-Mobile and SH-Mobile platforms.
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 R-Mobile and SH-Mobile platforms to evaluate the changes on the board and comment, as I dont have the board for testing, and also requesting an ACK.
