From 2d2682512f0faf4d09a696184bf3c0bb6838baca Mon Sep 17 00:00:00 2001 From: Palmer Dabbelt Date: Tue, 14 Apr 2020 13:43:24 +0900 Subject: riscv: Allow device trees to be built into the kernel Some systems don't provide a useful device tree to the kernel on boot. Chasing around bootloaders for these systems is a headache, so instead le't's just keep a device tree table in the kernel, keyed by the SOC's unique identifier, that contains the relevant DTB. This is only implemented for M mode right now. While we could implement this via the SBI calls that allow access to these identifiers, we don't have any systems that need this right now.
