My board is i.MX8MQ-EVK 700-29615 REVA.
I want to access PCIe dbi address in U-Boot.
But when I access pcie0@0x33800000 or pcie1@0x33c00000, it will hang.
I thought maybe it is the power-domain problem.
I add SMC calls myself before I access dbi address, somthing like:
1/10 (pcie0/pcie1 domain id)
But it still hangs. Did I miss something? Please help me.
