pci: mvebu: Add PCIe driver

2015-08-17T16:49:43Z

This adds a PCI driver for the controllers found on Marvell MVEBU SoCs. Besides the driver, this patch also removes the statically defined PCI MBUS windows. As they are not needed anymore, since this PCIe driver now creates the windows dynamically. Tested on Armada XP db-mv784mp-gp eval board using an Intel E1000 PCIe card in all 3 PCIe slots. And on the Armada 38x db-88f6820-gp eval board using this Intel E1000 PCIe card in the PCIe 0 slot. This port was done in cooperation with Anton Schubert.

Revert "dm: pci: Allow scan bridge child devices before relocation"

2015-08-14T15:50:11Z

This reverts commit df189d9ba3f8fd1bc67e3c0c3c4ace16cd065ee1. Unfortunately this commit breaks chromebook_link because it adds lots of PCI devices before relocation and there is not enough pre-reloc malloc() memory. Rathar then increase this memory, revert for now until we figure this out. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

dm: pci: Add a way to iterate through all PCI devices

2015-08-14T09:24:21Z

These functions allow iteration through all PCI devices including bridges. The children of each PCI bus are returned in turn. This can be useful for configuring, checking or enumerating all the devices. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

dm: pci: Provide friendly config access functions

2015-08-14T09:24:21Z

At present there are no PCI functions which allow access to PCI configuration using a struct udevice. This is a sad situation for driver model as it makes use of PCI harder. Add these functions. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

lib/fdtdec: Fix compiling warning caused by changing fdt_addr_t type

2015-08-06T13:31:13Z

fdt_addr_t is changed to phys_addr_t. The format in debug should be updated to %pa to match the type. Signed-off-by: York Sun CC: Simon Glass

pci: Indicate prefetchable memory allocate when debugging

2015-08-05T14:42:41Z

At present the PCI output displays 'Mem' when it allocates memory for a PCI device, whether it is prefetchable or not. There is a distinction since the memory comes from separate pools. Use 'Prf' instead of 'Mem' when allocating prefetchable memory. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

pci: Add a constant for an invalid interrupt

2015-08-05T14:42:41Z

Rather than using 0xff in the code, add a constant. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

pci: Fix up code for CONFIG_PCI_ENUM_ONLY

2015-08-05T14:42:41Z

This option is not used by any board but appears to still be useful, at least for testing. With recent commits it does not build, so fix it. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

pci: Use debug() instead of DEBUGF() in pci_auto.c

2015-08-05T14:42:41Z

This file does not need its own way of doing debug(). Clean it up to use the new way. Signed-off-by: Simon Glass Acked-by: Pavel Machek Reviewed-by: Bin Meng
