[U-Boot] PCIe driver for a new Freescale ARM64 SOC

Hi!

I'm with Freescale and we are currently working on bringing up a ARM64 SOC platform. The PCIe module is similar with the one used by the iMX family, being a Synopsys IP. However there are many differences in terms of the SOC integration (clocking, pin muxing, control registers) plus an additional internal DMA engine. I would like to address a question about the U-Boot driver approach. What would be an acceptable solution if we plan to make this driver upstreamable : 1. Use existing pcie-imx.c driver and parameterize according to the SOC platform 2. Create another driver file specific for the new family of SOCs Thank you!
