From: Andrew Victor Date: Fri, 1 Dec 2006 09:55:15 +0000 (+0100) Subject: [ARM] 3957/1: AT91: Physically mapped flash on DK and EK boards X-Git-Tag: upstream/snapshot3+hdmi~36573^2^2~14 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fcc63716a5ee93ec3d1043890e38753d53313b80;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git [ARM] 3957/1: AT91: Physically mapped flash on DK and EK boards This patch converts the old CONFIG_MTD_PHYSMAP_ options to the new physmap API by creating a physmap platform device for the NOR flash found on the Atmel AT91RM9200-DK and AT91RM9200-EK boards.
