Subject: [PATCH] arch/riscv/dts/sun20i-d1.dtsi: adjust plic compatible to
|
match opensbi
|
|
The T-HEAD PLIC is by default not accessible from S-mode, and access must be
|
enabled by opensbi to make it accessible to Linux.
|
|
The DTB is used both by U-Boot and opensbi (but the PLIC node is ignored by
|
U-Boot), so change the compatible to match what opensbi expects to fix a
|
crash during Linux boot:
