Merge tag 'u-boot-amlogic-20211007' of https://source.denx.de/u-boot/custodians/u-boot-amlogicWIP/07Oct2021
- Add new SoC ID for S905Y2 found in Radxa Zero
- pcie_dw_meson: fix usb fail when pci link fails to go up
- Sync Amlogic DT from Linux 5.14
- dwc3-meson-gxl: add AXG compatible
- dts: keep back HW order for MMC devices since change in Upstream Linux
- Cleanup local AXG DT USB nodes now everything is upstream
- distro_bootcmd: run pci enum for scsi_boot just like it is done for nvme_boot
- New Boards:
- Odroid-HC4: a variant of Odroid-C4 with 2 SATA ports (via PCIe-SATA bridge)
- Beelink GS-King X: A variant of the other Beelink board with 2 SATA ports (via USB3-SATA bridge)
- Banana Pi M5: another credit card SBC
- JetHub D1/H1: home automation controllers
- Radxa Zero: another RPi Zero sized SBC
