The existing net test executes a list of commands supplied by boardenv variable env__net_pre_commands. The idea was that boardenv would know whether the Ethernet device was attached to USB, PCI, ... and hence was the best place to put any commands required to probe the device. However, this approach doesn't scale well when attempting to use a single boardenv across multiple branches of U-Boot, some of which require "pci enum" to enumerate PCI and others of which don't, or don't /yet/ simply because various upstream changes haven't been merged down. This patch updates the test to require that the boardenv state which HW features are required for Ethernet to work, and lets the test itself map that knowledge to the set of commands to execute. Since this mapping is part of the test script, which is part of the U-Boot code/branch, this approach is more scalable. It also feels cleaner, since again boardenv is only providing data, rather than test logic. Signed-off-by: Stephen Warren <swarren@nvidia.com> Reviewed-by: Simon Glass <sjg@chromium.org>
