Commit Message

Ming Huang July 24, 2018, 6:32 a.m. UTC
we move all platform specific code to platform specific module, not
in PciHostBridge driver.
This is to prepare for switching to generic PciHostBridge driver, so

This patch add Hi161xPciPlatformLib and moves ATU initialization to
Hi161xPciPlatformLib and add api PciInitPlatform for PciPlatform driver.
