[U-Boot] [PATCH v3 0/29] Add additional core driver model features

[Simon Glass]

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 v3:
- Change pre-reloc fdt property to 'u-boot,dm-pre-reloc'

Changes in v2:
- Expand series to include all driver-model-required changes
- Improve wording in commit message
- Minor reword to comment for dm_init_and_scan()
- Reformat commit message slightly
- Remove change to board/rbc823/kbd.c, since it has been deleted
- Remove changes to deleted board/netphone/phone_console.c board/rbc823/kbd.c
- Rename struct device to struct udevice
- Return -ENODEV instead of -1 on error
- Update test output in doc/driver-model/README.txt
