Dear sir
We use the "SECO TrizepsVIII-Mini"(IMX8MM) CPU for Windows 10 IoT enterprise.
We try to add a PCI device by Ti XIO2001a , but the UEFI of Windows 10 IoT enterprise OS can not read it.
But, If we use the same hardware by reinstall the Linux OS, we can read the PCI device at the PCI Bus2 well before PCIE to PCI bridge(XIO2001a , PCIe bus1) .
Like this: IMX8MM PCIE pin->PCIE bridge(bus0)->PCIE to PCI bridge(bus1)->PCI fpga chip(Bus2)
We chceck the UEFI code of PCEI(iMX8PciExpress.c) in the NXP BSP of "mu_platform_nxp" folder.
(.\mu_platform_nxp\Silicon\ARM\NXP\iMX8Pkg\Drivers\PciExpress\iMX8PciExpress.c)
and Trizeps8mini_2GB.dsc file.
We make sure the UEFI code of PCEI for IMX8MM donot support the giMX8TokenSpaceGuid.PcdPcie1SwitchSupport.(Only support to read the PCIE BUS0,BUS1)
/////////////////////////////////////
I try to use the IMX8MQ PCIE Config Base address setting to "Trizeps8mini_2GB.dsc"(IMX8MM)
Trizeps8mini_2GB.dsc-->

# PCIE
#
# PCIe 1 Host config space is fixed at 0x33800000. The memory range from
# 0x18000000 - 0x1FFFFFFF is assigned for PCIe 1. The memory layout defined
# by the boot loader is as below
#
# PCIe Device Config Space : 0x18F00000 - 0x18F80000
# PCIe Device Memory Space : 0x18000000 - 0x1FF00000
giMX8TokenSpaceGuid.PcdPcie1Enable|TRUE
giMX8TokenSpaceGuid.PcdPcie1ControlBaseAddress|0x33800000

giMX8TokenSpaceGuid.PcdPcie1DeviceConfig0Base|0x1FF00000
giMX8TokenSpaceGuid.PcdPcie1DeviceConfig0Size|0x00080000

giMX8TokenSpaceGuid.PcdPcie1InternalRefClock|TRUE
giMX8TokenSpaceGuid.PcdPcie1MaxLinkSpeed|2
giMX8TokenSpaceGuid.PcdPcie1ResetGpio|TRUE
But I still only can read the PCIE to PCI device(XIO2000a), can not read the PCI device in the BUS2

How can I do to fix the problem.
Download the SECO uefi code at:
https://drive.google.com/file/d/1w0Sch16-pna1udHr7uvpUeMGo1zkHg6f/view?usp=drive_link
The zip file seco_uefi_code_mu_platform_nxp.zip have two folder:
mu_platform_nxp ->Add the pcie switch function to "Trizeps8mini_2GB"
mu_platform_nxp_org -> seco org uefi code only support pcie bus0,1
buildme64.sh ->firmware " "Trizeps8mini_2GB"" building command file.
We build the the firmwae file "firmware.tr8m.bin" by command " /buildme64.sh -b Tr8m -t all"
