arm64: dts: realtek: rtd129x: Carve out boot ROM from memory
Update DS418j, MeLE V9, PROBOX2 AVA, Zidoo X9S and DS418 /memory nodes to exclude 0..0x1efff from reg entry and update unit address to match. Add this region to /soc ranges and for now just update the /memreserve/s. Suggested-by: Rob Herring <robh@kernel.org> Fixes: 72a7786c0a0d ("ARM64: dts: Add Realtek RTD1295 and Zidoo X9S") Fixes: d938a964a966 ("arm64: dts: realtek: Add ProBox2 Ava") Fixes: a9ce6f854581 ("arm64: dts: realtek: Add MeLE V9") Fixes: cf976f660ee8 ("arm64: dts: realtek: Add RTD1293 and Synology DS418j") Fixes: 5133636e41a2 ("arm64: dts: realtek: Add RTD1296 and Synology DS418") Cc: James Tai <james.tai@realtek.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
