This series converts all Tegra boards to use driver model for PCI. The net effect should be no change in functionality.
A few additional features are added to make this possible: - Helper functions to support accessing 8- and 16-bit values within a 32-bit word - Fixing a build error for CONFIG_CMD_PCI_ENUM - Decoding the PCI ranges property such that configuration ranges are ignored - Supporting bus-master devices on boards where RAM does not start at 0
This series is tested on beaver. It is available at u-boot-dm/tegra-working.
Changes in v5: - Squash in Stephen's fixes from https://patchwork.ozlabs.org/patch/544727
Changes in v4: - Fix Kconig typo in commit message - Drop CONFIG_CMD_PCI_ENUM for p2371-2180 also - Fix merge conflict resolution error in v3 - Add compatible string for T210 (from Stephen Warren)
Changes in v3: - Rebase onto tegra/master - Enable DM_PCI for Tegra 210 family too
Changes in v2: - Update commit message to explain that the feature is not important - Drop the feature from tegra boards - Rename 'addr' to 'size' - Correct logic for use of gd->pci_ram_top - Update commit message to mention future work - Use the device_is_on_pci_bus() API - Leave pci_skip_dev() at the bottom of the file to reduce the diff size
