patch-arch_arm_lib_interrupts__64.c
patch-drivers_pci_pcie__rockchip.c
Log Message:
u-boot-rockpro64: fix broken PCI config space handling:
- Program bus number into the ECAM decoder for each access
- Use type 1 PCI config cycles for config spaces behind bridge
- Add a platform specific hack to the synchronous exception handler
to deal with PCI-e subsystem triggering data aborts when probing
nonexistent PCI devices.
- properly delay after deasserting reset for downstream devices to
have time to initialize.
Allows booting from PCI devices behind bridges and probing
devices other than 0:0:0 and 1:0:0.
