[edk2-devel] [edk2-platforms][PATCH 0/2] Fixing FDT handling on Pi 3

Posted by Andrei Warkentin 3 years, 12 months ago

Dear all,

This patch set finishes what I started with the Pi 4 fix for
the regression seen with newer VideoCore firmware, where a
device tree passed via config.txt would not be detected by UEFI.

This makes VPU-passed FDT work again on Pi 3 variants. This also
cleans up the docs around correctly using FDT, hopefully solving
some of the frustrations seem around using this correctly.

Andrei Warkentin (2):
  RPi3/RPi4: fix RPi 3 VPU-passed FDT handling by unifying with RPi4
    implementation
  RPi: update Pi3 and Pi4 readmes with correct info on FDT handling
