Re: [PATCH v9 0/8] pci_expander_brdige:acpi: Support pxb-pcie for ARM

  Hi,

Looking at the whole series for the first time after being Cc'ed on one
of the patches.

I'm wondering whenever it would be easier to just have multiple
gpex devices (one per numa node)?

Also I think you don't have to use the x86-style crs handling.
Just pick address ranges for the new pci root.  Linux should
cope just fine.  When adding the pci root to the device tree
edk2 can handle this too (might require some firmware tweaks
though).

take care,
  Gerd
