[PATCH] ARM: dts: wpcm450: Add nuvoton,shm = <&shm> to FIU node

From: Jonathan Neuschäfer
Date: Sun Jan 29 2023 - 06:26:33 EST


The Flash Interface Unit (FIU) should have a reference to the Shared
Memory controller (SHM) so that flash access from the host (x86 computer
managed by the WPCM450 BMC) can be blocked during flash access by the
FIU driver.
