* dm: pci: Allow disabling auto-config for a deviceSimon Glass2020-04-161-0/+23
| | | | | | | | Add a means to avoid configuring a device when needed. Add an explanation of why this is useful to the binding file. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* dm: pci: Allow delaying auto-config until after relocationSimon Glass2019-12-151-0/+24
| | | | | | | | | | | | | | At present PCI auto-configuration happens in U-Boot both before and after relocation. This is a waste of time and may mess up static addresses used in board_init_f(). Adjust the code to supporting doing auto-configuration once, after relocation, under control of a device-tree property. This is needed for Apollo Lake for debugging the silicon-init code. Once the UART is moved to a different MMIO address the debug UART does not work and any debug output in Apollo Lake's arch_fsp_init_r() causes a hang.
