Subject: [PATCH 1/3] PCI: controller: al: select CONFIG_PCI_ECAM

From: Arnd Bergmann <arnd@...db.de>

Compile-testing this driver without ECAM support results in a link
failure:

ld.lld: error: undefined symbol: pci_ecam_map_bus
>>> referenced by pcie-al.c
>>>               pci/controller/dwc/pcie-al.o:(al_pcie_map_bus) in archive drivers/built-in.a

Select CONFIG_ECAM like the other drivers do.
