Yes, but all the other boards use nnn k, so let's stick with k . I don't want one value to stick out like a sore thumb. >> Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> > > Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> > > Gr{oetje,eeting}s, > > Geert >

Drop the MTD partitioning from DT, since it does not describe HW and to give way to a more flexible kernel command line partition passing. To retain the original partitioning, assure you have enabled CONFIG_MTD_CMDLINE_PARTS in your kernel config and add the following to your kernel command line: mtdparts=spi0.0:256k@0(loader),4096k(user),-(flash) Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Geert Uytterhoeven <geert+renesas@glider.be> Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Cc: Simon Horman <horms+renesas@verge.net.au> Cc: Wolfram Sang <wsa@the-dreams.de> Cc: linux-renesas-soc@vger.kernel.org --- arch/arm/boot/dts/r8a7790-lager.dts | 21 --------------------- 1 file changed, 21 deletions(-)
