From: Paul Burton Date: Thu, 14 Sep 2017 22:05:07 +0000 (-0700) Subject: sh: Use asm-generic/io.h X-Git-Tag: v2017.11-rc2~149 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=505fe9cdd0e9613ee1f081b58d2fb69bdf1c1eae;p=u-boot sh: Use asm-generic/io.h Convert the sh architecture to make use of the new asm-generic/io.h to provide address mapping functions. As the generic implementations are suitable for sh this is primarily a matter of moving code. Feedback from architecture maintainers is welcome.
