PCIe support for U-boot

Does anybody know of PCIe for T30 for UBoot bootloader?

Hi Bob,
This feature is not currently implemented in U-Boot provided with Linux for Tegra (L4T), though some work was done in the past to prototype such support. If you have interest in this feature, let’s continue your thread on the public U-Boot mailing list. A few suggestions have been provided there, and we may be able to provide additional guidance.

Thank you,
Eric and the L4T team
