The BCM2711 has two USB 2.0 IPs: A Broadcom XHCI USB 2.0 controller and
a Synopsys DWC2 USB 2.0 Host/Device controller. When USB boot is used
the former is active. Make sure the driver has the correct device tree
compatible.
* Add NVMe and XHCI USB driver fix for Raspberry Pi
Add patch which fixes NVMe read reliability and allows to compile the
XHCI USB driver (for Compute Module 4).
* Enable Broadcom XHCI driver for Compute Module 4
The BCM2711 has two USB 2.0 IPs: A Broadcom XHCI USB 2.0 controller and
a Synopsys DWC2 USB 2.0 Host/Device controller. When USB boot is used
the former is active. Make sure U-Boot has the driver built-in for that
IP.
* Add U-Boot patches for NVMe boot support
Add NVMe to boot order. Fix NVMe support on 64-bit Raspberry Pi devices.
This is useful for Raspberry Pi Compute Module 4 IO Board where a native
NVMe can be plugged in.
* Enable NVMe support for Raspberry Pi 4
Our machine configuration rpi4 and rpi4_64 work on the Compute Module IO
Board. In this configuration a NVMe SSD can be used. Therefor, enable
support for NVMe in the Raspberry Pi 4 configurations.
Note: Regular Raspberry Pi devices will not notice a difference as the
"nvme scan" command will return very quickly and not find a NVMe on the
PCIe bus.
* Use built-in NVMe support in Kernel for NVMe boot 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.
