Issue booting with PCIE SATA switches (ASMedia ASM1184e)

[Archfx]

Is the latest image tested with PCIe switches?

My CM5 boots with no issues on the RPI-CM4 carrier board. However, does not boot on a NAS board that has "ASMedia ASM1184e" PCIE SATA switch. The blue LED is always stuck in weak solid mode.

These are the DMSEG when the board is booted on RPI-CM4 board.

This issue was there in the RPI kernel as well. Adding a delay into the BCM2711 driver fixed the RPI CM4 issue.

However, I tried compiling my kernel with the above changes using bsp, but stil the issue is there.

Any pointer?
