Description

When the bootloader configures PCI devices, it improperly disables excessively large memory regions. If a card offers a memory region that would exhaust the PCI address space, the region is being reconfigred to PCI address 0, causing an address conflict with the onboard pci peripherals, which causes RTEMS to abend due to not finding any onboard hardware.

Release:
rtems-4.6.2

Environment:
all motorola_shared targets, bootloader PCI setup issue
