Bug#1052610: u-boot-rockchip: not possible to boot from SSDs connected to SATA PCIe DeLOCK 9049

[Chris Vogel]

Package: u-boot-rockchip
Version: 2023.07+dfsg-1_arm64
Severity: normal

Hardware: RockPro64/4GB + DeLOCK 90498 SATA PCIe + 2 SATA SSDs

It's not possible to boot of the connected disks.

u-boot consoles output on a failed boot (falling back to eMMC):

On the other hand it is possible to use the connected SATA SSDs from an Armbian 23.8.1 Bullseye with Linux 4.4.213-legacy-rockchip64. Here's part of the dmesg showing the important part of the initialisation:

```
rockchip-pcie f8000000.pcie: missing "memory-region" property
PCI host bridge /pcie@f8000000 ranges:
rockchip-pcie f8000000.pcie: invalid power supply
rockchip-pcie f8000000.pcie: wait 1000 ms (from device tree) before bus scan
rockchip-pcie f8000000.pcie: PCI host bridge to bus 0000:00
pci_bus 0000:00: root bus resource [bus 00-1f]
pci_bus 0000:00: root bus resource [mem 0xfa000000-0xfbdfffff]
pci_bus 0000:00: root bus resource [io 0x0000-0xfffff] (bus address [0xfbe00000-0xfbefffff])
```

**But** this only works if u-boot didn't try to initialise the card first. If u-boot already failed to use the card the according dmesg looks like the following and neither the PCIe card nor the SSDs are visible to Linux:

```
rockchip-pcie f8000000.pcie: missing "memory-region" property
PCI host bridge /pcie@f8000000 ranges:
rockchip-pcie f8000000.pcie: invalid power supply
