Implement "pci enum" command for CONFIG_DM_PCI

2016-01-29T04:01:23Z

With CONFIG_DM_PCI enabled, PCI buses are not enumerated at boot, as they are without that config option enabled. No command exists to enumerate the PCI buses. Hence, unless some board-specific code causes PCI enumeration, PCI-based Ethernet devices are not detected, and network access is not available. This patch implements "pci enum" in the CONFIG_DM_PCI case, thus giving a mechanism whereby PCI can be enumerated. do_pci()'s handling of case 'e' is moved into a single location before the dev variable is assigned, in order to skip calculation of dev. The enum sub-command doesn't need the dev value, and skipping its calculation avoids an irrelevant error being printed. Using a command to initialize PCI like this has a disadvantage relative to enumerating PCI at boot. In particular, Ethernet devices are not probed during PCI enumeration, but only when used. This defers setting variables such as ethact, ethaddr, etc. until the first network-related command is executed. Hopefully this will not cause further issues. Perhaps in the long term, we need a "net start/enum" command too? Signed-off-by: Stephen Warren Reviewed-by: Simon Glass Reviewed-by: Bin Meng
