[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Minios-devel] [UNIKRAFT PATCH RFC 17/23] plat/pci_bus: Split specific code into arch directory
There are significant difference for pci controller on arm64 and x86.
On arm64, only pci ecam is supported.
Hence split arch dependant codes into arch specific directory
No functional changes in this patch
