Subject: [PULL 04/30] hw/riscv: hart: Add a new 'resetvec' property
Date: Thu, 10 Sep 2020 11:09:12 -0700	[thread overview]
Message-ID: <20200910180938.584205-5-alistair.francis@wdc.com> (raw)
In-Reply-To: <20200910180938.584205-1-alistair.francis@wdc.com>

From: Bin Meng <bin.meng@windriver.com>

RISC-V machines do not instantiate RISC-V CPUs directly, instead
they do that via the hart array. Add a new property for the reset
vector address to allow the value to be passed to the CPU, before
CPU is realized.
