Platform/NXP-Added NXP PCI Host Bridge Driver

[edk2] [PATCH edk2-platforms 0/3] Platform/NXP-Added NXP PCI Host Bridge Driver

Posted by Vabhav 6 years, 3 months ago

Following patches will add support of NXP PCI Host Bridge Driver in edk2-platforms directory 'edk2-platforms/Platform/NXP'

Updated Directory structure for added folders in 'edk2-platforms/Platform/NXP' will be:

Platform/NXP/Drivers/PciHostBridgeDxe/
|-- PciHostBridgeDxe.c
|-- PciHostBridgeDxe.inf
`-- PciRootBridgeIo.c

Platform/NXP/Library/PciHostBridgeLib/
|-- PciCntrl.c
|-- PciHostBridgeLib.inf
`-- PciRbLib.c

In Platform/NXP/Library
PciHostBridgeLib librady is added

In Platform/NXP/Drivers:
PciHostBridgeDxe driver is added

Please review and look forward for your support in upstreaming the patches in edk2-platforms.

Why do you need a new PciHostBridgeDxe driver? Can't you use the one
in MdeModulePkg instead?

Please put these in Silicon/NXP, not Platform/NXP

Using  PciHostbridge dxe driver with changes for multiple(three)  host bridge instances with 1:1 mapping  for HostBridge:Root bridge(Hb:Rb), I will evaluate MdeModulePkg for
Multiple host bridge support

Reference is taken from ARM/Hisilicon directory structure , We plan to put only chassis specific code in Silicon/NXP and Drivers, Library in Platform/NXP.
Please suggest if there is any specific reason for putting them in Silicon/NXP?

You will need to re-implement PciSegmentLib for that. Please find an
example here:

https://git.linaro.org/leg/noupstream/edk2-platforms.git/tree/Silicon/Socionext/SynQuacer/Library/SynQuacerPciSegmentLib?h=developer-box

Yes. Platform/ contains platform specific pieces, e.g., board level
driver, device tree images, .DSC files etc. Libraries and drivers that
can be shared between different platforms using the same SoC belong in
Silicon/NXP.
