This series add support for the ROCK 5B+ variant to the existing
rock5b-rk3588 defconfig taget.
The ROCK 5B+ variant is detected based on DRAM type (LPDDR5) and SARADC
channel 5, the read out value is expected to be close to 4095 (1.8v) on
5B+ variants.
Features tested on a ROCK 5B+ v1.2:
- SD-card boot
- eMMC boot
- SPI flash boot
- PCIe/NVMe
- Ethernet
- USB/TCPM
I also confirmed that the following things are working:
- uSD card (boot/mmc info)
- SPI flash (sf probe)
- PCIe (pci enum)
- NVMe (nvme scan)
- Ethernet (ping)
- USB (usb start)
