The sandbox driver will now generate response traffic to exercise the ping command even when no network exists. This allows the basic data pathways of the DM to be tested. Signed-off-by: NJoe Hershberger <joe.hershberger@ni.com> Reviewed-by: NSimon Glass <sjg@chromium.org>

Stop forcing drivers to call net_process_received_packet() - formerly called NetReceive(). Now the uclass will handle calling the driver for each packet until the driver errors or has nothing to return. The uclass will then pass the good packets off to the network stack by calling net_process_received_packet(). Signed-off-by: NJoe Hershberger <joe.hershberger@ni.com>

Previously the net functions would access memory assuming physmem did not need to be mapped. In sandbox, that's not the case. Now we map the physmem specified by the user in loadaddr to the buffer that represents that space.

netretry previously would only retry in one specific case (your MAC address is not set) and no other. This is basically useless. In the DM implementation for eth it turns this into a completely useless case since an un-configured MAC address results in not even entering the NetLoop. The behavior is now changed to retry any failed command (rotating through the eth adapters if ethrotate != no). It also defaulted to retry forever. It is now changed to default to not retry Signed-off-by: NJoe Hershberger <joe.hershberger@ni.com> Reviewed-by: NSimon Glass <sjg@chromium.org>

This value is not used by the network stack and is available in the global data, so stop passing it around. For the one legacy function that still expects it (init op on old Ethernet drivers) pass in the global pointer version directly to avoid changing that interface.

Move chromebook_link over to driver model for PCI. This involves: - adding a uclass for platform controller hub - removing most of the existing PCI driver - adjusting how CPU init works to use driver model instead - rename the lpc compatible string (it will be removed later) This does not really take advantage of driver model fully, but it does work. Furture work will improve the code structure to remove many of the explicit calls to init the board. Signed-off-by: NSimon Glass <sjg@chromium.org>

Some uclasses want to set up a device before it is probed. Add a method for this. An example is with PCI, where a PCI uclass wants to set up its private data for later use. This allows the device's uclass() method to make calls whcih use that data (for example, read PCI memory regions from device tree, set up bus numbers). Signed-off-by: NSimon Glass <sjg@chromium.org>

At present the device is not active when the probe() method is called. But some probe() methods want to set up the device and this can involve accessing it through normal methods. For example a PCI bus may wish to set up its PCI parameters using calls to pci_hose_write_config_dword() and similar. At present this does not work because every such call within the probe() method sees that the device is not active and attempts to probe it. Already we mark the device as probed before calling the uclass post_probe() method. This is a subtle change but I believe the new approach is better. Since the scope of the change is only the probe() method and all its callees it should still be within the control of the board author. Signed-off-by: NSimon Glass <sjg@chromium.org>
