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.
