Subject: sh64: fix up memory offset calculation.
X-Git-Tag: firefly_0821_release~9833^2~3107^2~28
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=19f6b8b44e3f633d5d7d1ed68848b1eb89a1e800;p=firefly-linux-kernel-4.4.55.git

sh64: fix up memory offset calculation.

The linker script offsets were broken by the recent 29/32-bit
integration, so this fixes it up for sh64.
