ARM: shmobile: r7s72100: Remove legacy board support
There's no legacy board anymore, genmai now boots with multiplatform support only. Remove the leftovers. Makefile.boot portion pointed out by Paul Bolle. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Acked-by: Wolfram Sang <wsa@sang-engineering.com> Cc: Paul Bolle <pebolle@tiscali.nl> [horms+renesas@verge.net.au: squashed in patch containing Makefile.boot change] Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
