Subject: [U-Boot] [PATCH v2 0/1] Pass board revision and serial number to the
Date: Wed, 20 Feb 2019 13:09:12 +0100 [thread overview]
Message-ID: <cover.1550664195.git.tossel@gmail.com> (raw)
Raspberry Pi proprietary bootloader adds this information to the device
tree to finally land in /proc/cpuinfo.
It is then used by some userspace tools. In particular `gpio` tool from
WiringPi suite would use the wrong register mapping when this
information is missing from /proc/cpuinfo.
