42c64d1bc9 sandbox: Update PCI nodes in dts files
The way the PCI nodes are written today causes a number of warnings if
we stop disabling some of the warnings we pass to DTC.  As these
warnings aren't disabled in current Linux Kernel builds, we should aim
to not disable them here either, so rewrite these slightly.  Update the
driver model doc as well.

a466db5adb sandbox: Support changing the LCD colour depth
Add a new device-tree property to control the colour depth. At present we
support 16bpp and 32bpp.

While we are here, update the code to use livetree.

9b69ba4a78 pci: sandbox: Move the emulators into their own node
Sandbox pci works using emulation drivers which are currently children of
the pci device:

	pci-controller {
		pci@1f,0 {
			compatible = "pci-generic";
			reg = <0xf800 0 0 0 0>;
			emul@1f,0 {
				compatible = "sandbox,swap-case";
			};
		};
	};

In this case the emulation device is attached to pci device on address
f800 (device 1f, function 0) and provides the swap-case functionality.

However this is not ideal, since every device on a PCI bus has a child
device. This is only really the case for sandbox, but we want to avoid
special-case code for sandbox.

Worse, child devices cannot be probed before their parents. This forces
us to use 'find' rather than 'get' to obtain the emulator device. In fact
the emulator devices are never probed. There is code in
sandbox_pci_emul_post_probe() which tries to track when emulators are
active, but at present this does not work.

A better approach seems to be to add a separate node elsewhere in the
device tree, an 'emulation parent'. This could be given a bogus address
(such as -1) to hide the emulators away from the 'pci' command, but it
seems better to keep it at the root node to avoid such hacks.

Then we can use a phandle to point from the device to the correct
emulator, and only on sandbox. The code to find an emulator does not
interfere with normal pci operation.

Add a new UCLASS_PCI_EMUL_PARENT uclass which allows finding an emulator
given a bus, and finding a bus given an emulator. Update the existing
device trees and the code for finding an emulator.

This brings PCI emulators more into line with I2C.

099ed45c6c test: check u-boot properties in SPL device tree
Add a test to check the management of the U-boot relocation properties
for device tree SPL generation (fdtgrep result) and platdata:
- 'dm-pre-proper' and 'dm-tpl' not included in SPL
- 'dm-pre-reloc' and 'dm-spl' included in SPL

dc8c91abb7 sandbox: Create a common sandbox DT
At present sandbox and sandbox64 have duplicated nodes. This is hard to
maintain since changes in one need to be manually added to the other.

Create a common file to solve this problem.
