Subject: [PATCH edk2-platforms 0/2] Platform/RaspberryPi3: add RNG support
Date: Sat, 16 Feb 2019 11:34:20 +0100 [thread overview]
Message-ID: <20190216103422.10907-1-ard.biesheuvel@linaro.org> (raw)
Add a RNG driver for the BCM283x and wire it up for the Raspberry Pi 3
platform so that the random number generator is accessible to the OS
loader via the EFI_RNG_PROTOCOL. This is used by the KASLR implementation
in the arm64 Linux kernel to randomize the placement of various parts of
the kernel.
Changes since v2:
- move the RNG specific SoC definitions into the Bcm2836.h common header
- add patch that wires up the driver into the RPi3 platform
