We only have a single U-Boot version currently, so there is no value in
storing the patch file in a version specific directory. This makes sure
U-Boot 2021.10 final release also has fileenv support.
The bump to U-Boot 2021.10-rc5 also makes quite some patches obsolete
since they are already part of U-Boot.
This also removes a patch which disables framebuffer support on
Raspberry Pi: Framebuffer support seems to work fine in todays
U-Boot/Linux combination. It can help debug boot problems on Raspberry
Pi devices. Without the patch framebuffer support will be enabled by
default.
* Backport USB PCIe/XHCI patches to U-Boot 2020.07
Backport relevant patches required to make PCIe/USB XHCI work.
* Backport/integrate PCIe device tree changes from upstream Linux
U-Boot uses the device tree provided by upstream Linux. Make sure the
device tree has the relevant chanages to make VL805 USB controller
reset work.
* Document RPi 4 USB mass storage support (#746)
Unfortunately builds for 32-bit seem to lead to freezes. Conservatively
only update to 2020.07 for 64-bit builds.
