Subject: [PATCH 1/6] arch: riscv: add support for building DTB files from DT source data
Date: Thu, 11 Apr 2019 01:42:59 -0700	[thread overview]
Message-ID: <20190411084304.5072-2-paul.walmsley@sifive.com> (raw)

Similar to ARM64, add support for building DTB files from DT source
data for RISC-V boards.

This patch starts with the infrastructure needed for SiFive boards.
Boards from other vendors would add support here in a similar form.
