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.

and ZRELADDR

Thanks for the patch. I believe we enable this for the multiplatform
case already. The legacy case still supports ZBOOT_ROM and boards that
don't work with AUTO_ZRELADDR, so because of this we intentionally
don't enable it there.
What is the reason you want to add it here?
Thanks,

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.

FTTC broadband for 0.8mile line: 5.8Mbps down 500kbps up. Estimation
in database were 13.1 to 19Mbit for a good line, about 7.5+ for a bad.
Estimate before purchase was "up to 13.2Mbit".
