When CONFIG_OF_PLATDATA is enabled, we cannot use the u-boot,dm-pre-reloc
device tree property since the device tree is not available. However,
dt-platdata.c only includes devices which would have been present in the
device tree, and we can assume that all such devices are needed for SPL.
If they were not needed, they would have been omitted to save space.
So in this case, bind all devices regardless of the u-boot,dm-pre-reloc
setting. This avoids needing to add a DM_FLAG_PRE_RELOC to every driver,
thus affecting U-Boot proper also.

At present assert() is not supported with tiny-printf, so when DEBUG is
enabled a build error is generated for each assert().
Add an __assert_fail() function to correct this. It prints a message and
then hangs.

Start up the test devices. These print out of-platdata contents, providing a

It is useful to be able to build SPL for sandbox. It provides additional
build coverage and allows SPL features to be tested in sandbox. However
it does not need worthwhile to always create an SPL build. It nearly
doubles the build time and the feature is (so far) seldom used.
So for now, create a separate build target for sandbox SPL. This allows
experimentation with this new feature without impacting existing workflows.

Overriding the final link rule is possible with U-Boot proper. It us used to

Sandbox includes this code to provide build coverage. While we retain this
feature we should have sandbox build it. Sandbox does not in fact use the

Add support for Advantech SOM-DB5800 with the SOM-6867 installed.
This is very similar to conga-qeval20-qa3-e3845 in that there is a
reference carrier board (SOM-DB5800) with a Baytrail based SoM (SOM-6867)
installed.
Currently supported:
- 2x UART (From ITE EC on SOM-6867) routed to COM3/4 connectors on
SOM-DB5800.
- 4x USB 2.0 (EHCI)
- Video
- SATA
- Ethernet
- PCIe
- Realtek ALC892 HD Audio
Pad configuration for HDA_RSTB, HDA_SYNC, HDA_CLK, HDA_SDO
HDA_SDI0 is set in DT to enable HD Audio codec.
Pin defaults for codec pin complexs are not changed.
Not supported:
- Winbond Super I/O (Must be disabled with jumpers on SOM-DB8500)
- USB 3.0 (XHCI)
- TPM

There are quite a number of BayTrail boards that uses an external

better to have a Kconfig option to enable the internal UART.
So far BayleyBay and MinnowMax boards are using internal UART as
the U-Boot console, enable this on these two boards.
