It took a little while to figure this out, so this patch adds documentation
to help the next person who needs to do this.

Add basic support for MMC, providing a uclass which can set up an MMC
device. This allows MMC drivers to move to using driver model.

Add a simple uclass for LEDs, so that these can be controlled by the device
tree and activated when needed. LEDs are referred to by their label.
This implementation requires a driver for each type of LED (e.g GPIO, I2C).

Many SoCs have a number of system controllers which are dealt with as a
group by a single driver. It is a pain to have to add lots of compatible
strings and/or separate drivers for each. Instead we can identify the
controllers by a number and request the address of the one we want.
Add a simple implementation of this which can be used by SoC driver code.

Add a simple implementaton of register maps, supporting only direct I/O
for now. This can be enhanced later to support buses which have registers,
such as I2C, SPI and PCI.
It allows drivers which can operate with multiple buses to avoid dealing
with the particulars of register access on that bus.

In some rare cases it is useful to be able to locate a device given a device
tree node offset. An example is when you have an alias that points to a node
and you want to find the associated device. The device may be SPI, MMC or
something else, but you don't need to know the uclass to find it.
Add a function to do a global search for a device, given its device tree
offset.

In SPL it is sometimes useful to be able to obtain a dump of the current
driver model state. Since commands are not available, provide a way to
directly call the functions to output this information.
Adjust the existing commands to use these functions.

This does not actually help any current arch. For x86 it makes it harder
to call (requires stack) and for ARM it has no effect. Drop it.

U-Boot uses structures for hardware access so it is important that these
structures are correct. Add a way of asserting that a structure member is
at a particular offset. This can be created using the datasheet for the
hardware.
This implementation uses Static_assert() since BUILD_BUG_ON() only works
within functions.

These have been sent upstream but not accepted to libfdt. For now, bring

Property names are stored in a string table. When a node property is
removed, the string table is not updated since other nodes may have a
property with the same name.
Thus it is possible for the string table to build up a number of unused
strings. Add a function to remove these. This works by building a new device
tree from the old one, adding strings one by one as needed.

Offer to display the available image types in help. Also, rather than

The agreed split of the top of memory is 256M for debug server and 256M
for MC. This patch implements the split.
In addition, the MC mem must be 512MB aligned, so the amount of memory

Avoid clearing the reg property in the memory DT node if no memory
banks have been specified for a board (CONFIG_NR_DRAM_BANKS == 0).
This allows boards to let U-Boot skip the DT memory tinkering in case
other firmware has already setup the node properly before.
This should be safe as all callers of fdt_fixup_memory_banks that use
a computed <banks> value put at least 1 in there.
Add some documentation comments to the header file.

Currently PCI expansion ROM address is assigned by a call to
pciauto_setup_rom() outside of the pci auto config process.
This does not work when expansion ROM is on a device behind
PCI bridge where bridge's memory limit register was already
programmed to a value that does not cover the newly assigned
expansion ROM address. To fix this, we should configure the
ROM address during the auto config process.
