From aca8bb5cc332f0ffdf4249e76b0a56716f98bef0 Mon Sep 17 00:00:00 2001 From: Alan Luck Date: Fri, 14 Oct 2022 17:26:27 +1100 Subject: [PATCH] ath79: expand rootfs for DIR-825-B1 with unused space Expand currently unused flash space to roofs for DIR-825-B1 by using the same flash space as the old ar71xx big image without moving the caldata. With some testing this partition is use by the OEM firmware but if changed is regenerated which allows reverting to OEM firmware Signed-off-by: Alan Luck --- .../ath79/dts/ar7161_dlink_dir-825-b1.dts | 27 ++++++++++++++----- 1 file changed, 21 insertions(+), 6 deletions(-) diff --git a/target/linux/ath79/dts/ar7161_dlink_dir-825-b1.dts b/target/linux/ath79/dts/ar7161_dlink_dir-825-b1.dts index 8188027c4c..b701f15421 100644 --- a/target/linux/ath79/dts/ar7161_dlink_dir-825-b1.dts +++ b/target/linux/ath79/dts/ar7161_dlink_dir-825-b1.dts @@ -109,6 +109,23 @@ }; }; }; + + virtual_flash { + compatible = "mtd-concat"; + devices = <&fwconcat0 &fwconcat1>; + + partitions { + compatible = "fixed-partitions"; + #address-cells = <1>; + #size-cells = <1>; + + partition@0 { + compatible = "denx,uimage"; + label = "firmware"; + reg = <0x0 0x0>; + }; + }; + }; }; &usb1 { @@ -186,9 +203,8 @@ read-only; }; - partition@50000 { - compatible = "denx,uimage"; - label = "firmware"; + fwconcat0: partition@50000 { + label = "fwconcat0"; reg = <0x050000 0x610000>; }; @@ -198,10 +214,9 @@ read-only; }; - partition@670000 { - label = "unknown"; + fwconcat1: partition@670000 { + label = "fwconcat1"; reg = <0x670000 0x190000>; - read-only; }; }; }; -- 2.30.2
