Subject: [PATCH 0/2] Raspberry Pi 4 VL805 firmware load
Date: Tue, 28 Apr 2020 19:44:48 +0200	[thread overview]
Message-ID: <20200428174449.27953-1-nsaenzjulienne@suse.de> (raw)

Newer revisions of the RPi4 need their xHCI chip, VL805, firmware to be
loaded explicitly. Earlier versions didn't need that as they where using
an EEPROM for that purpose. This series takes care of setting up the
relevant infrastructure and run the firmware loading routine at the
right moment.

Patch 2 is a little invasive, but I couldn't find a mechanism in u-boot
similar to Linux's PCI quirks.
