Subject: [PATCH] sh: Remove sh_pcic_io_xxx function from Solution Engine IO code
Date: Wed, 18 Jun 2008 09:32:14 +0000 [thread overview]
Message-ID: <4858D61E.6050204@renesas.com> (raw)
sh_pcic_io_xxx function are very old.
In linux-2.4, mrshpc_ss socket driver used this function.
But there is not this driver to the present kernel.
I deleted these cords and checked operation.
