This series includes a number of base driver model enhancements, mostly targeted at pre-relocation and to enable buses to be easily implemented.
With the device tree, child nodes for buses can now be scanned to create child devices, and bus-related information about each child can be stored. Children can be numbered as a core driver model feature in U-Boot (e.g. SPI bus 0 chip select 3).
Driver model now supports operation prior to relocation, assuming a suitable malloc() implementation is available.
Several changes are added to permit driver model to be available early after relocation, since we are unable to access any device until driver model is ready.
This series is available at u-boot-dm.git branch 'working'.
Changes in v2: - Remove change to board/rbc823/kbd.c, since it has been deleted - Reformat commit message slightly - Remove changes to deleted board/netphone/phone_console.c board/rbc823/kbd.c - Rename struct device to struct udevice - Update test output in doc/driver-model/README.txt - Minor reword to comment for dm_init_and_scan() - Return -ENODEV instead of -1 on error - Improve wording in commit message - Improve wording in commit message - Expand series to include all driver-model-required changes
