Subject: [U-Boot] [PATCH 08/12] rockchip: misc: read cpuid either from efuse or otp
Date: Fri, 25 Oct 2019 01:27:59 +0200	[thread overview]
Message-ID: <20191024232803.10338-9-heiko@sntech.de> (raw)
In-Reply-To: <20191024232803.10338-1-heiko@sntech.de>

From: Heiko Stuebner <heiko.stuebner@theobroma-systems.com>

Newer Rockchip socs use a different ip block to handle one-time-
programmable memory, so depending on what got enabled get the cpuid
from either source.
