[PATCH 2/2] riscv: dts: sophgo: sg2002-milkv-duo256m: drop reserved memory node

From: Andrei Lalaev

Date: Mon Sep 21 2026 - 11:17:46 EST


The current FSBL can load firmware to any address and can also
disable the coprocessor. Therefore, FSBL should modify the device
tree at runtime. Remove the node accordingly.
