At present ivybridge is the only x86 implementation that includes a reasonably full board init. This means there is a lot more code than with a board that uses FSP (even then we don't have memory init or graphics init code).
This code does not use proper drivers for the devices and so its use of driver model is limited. This series refactors the code to improve this. In particular it drops use of the old x86_pci_...() API in favour of dm_pci_...(). The latter requires that each PCI device has a driver.
A few very minor driver model improvements are added to support this. Also a Northbridge uclass is added - this could instead be done with the syscon, so comments are well as to which is best.
A small amount of additional work will be needed to remove use of the x86_pci_...() in arch/x86, but this series represents the bulk of it.
Changes in v2: - Fix -EEPFNOSUPPORT typo - Add missing of_match member init so that ehci_pci_ids[] is used - Add missing 'given' word - Drop unnecessary/incorrect non-DM code in dm_pci_run_vga_bios() - Drop unused 'gen-dec' device tree property - Drop the init() method in the PCH - Rename this commit from 'x86: ivybridge: Set up the PCH init' - Drop unnecessary DECLARE_GLOBAL_DATA_PTR - Drop explicit PCH probe - Drop LPC init method - Rename patch from 'Add an init() method for the bd82x6x LPC' - Update to drop LPC init method and use probe() instead - Fix 'baords' typo in the commit message - Add a comment as to why we are initing the devices again - Drop northbridge_enable() - Rename from 'Move northbridge setup to the northbridge driver' - Drop this unnecessary init - Rename the AHCI uclass to DISK - Update to use the disk uclass - Update to use the disk uclass - Drop unnecessary IRQ and command register init - Update to use LPC probe() method instead of init() - Drop the special compatible string in chromebook_link.dts - Expand the Kconfig help a little - Avoid needing the pch device to set up the USB bar - Fix incorrect bits in bridge_silicon_revision() comment - Rename from 'Convert EHCI init to use the DM PCI API' - Drop this init - Fix the USB PCI address in the device tree - Enable SYSCON and REGMAP for panther to avoid a build error - Drop bd82x6x_pci_init() function and associated DM-conversion patch - Drop LPC init method an 'Add an init() method to the LPC uclass' patch
