fcf45692b7 dm: pci: remove pci_bus_to_hose(0) calling
There may be multiple PCIe controllers in a SoC.
It is not correct that always calling pci_bus_to_hose(0) to get
the first PCIe controller for the PCIe device connected other
controllers. We just remove this calling because hose always point
the correct PCIe controller.

08c11aaefb i2c: i2c-cdns: Implement workaround for hold quirk of the rev 1.0
Revision 1.0 of this IP has a quirk where if during a long read transfer
the transfer_size register will go to 0, the master will send a NACK to
the slave prematurely.
The way to work around this is to reprogram the transfer_size register
mid-transfer when the only the receive fifo is known full, i.e. the I2C
bus is known non-active.
The workaround is based on the implementation in the linux-kernel.

3296eeff8a exynos: video: Enable stdout env var backward compatibility for LCD
Commit bb5930d5c9 ("exynos: video: Convert several boards to driver
model for video") converted the Exynos Chromebooks machines to use DM
for video, but this breaks backward compatibility with the stdout env
var since now stdout is expected to be "vidconsole" instead of "lcd".

This causes display to not work when updating u-boot on these boards
if the old stdout env var is used. Since these are consumer devices,
there's no easy way to have a serial console so users may be confused
thinking that u-boot failed to boot, or in the best case will need to
update the stdout env var blindly to make the display to work again.

There's a CONFIG_VIDCONSOLE_AS_LCD config option to workaround this,
so enable it in the Chromebooks' default configuration files to allow
users to change their stdout env var before the workaround is removed.

26b09c022a ARM: uniphier: move SBC and Support Card init code to U-Boot proper
Initialize SBC and Support Card in U-Boot proper instead of SPL.

We may run different firmware (ex. ARM Trusted Firmware) before
U-Boot, and basic SoC initialization may be done there.  In that
case, SPL may not be used.

The motivation for preparing SBC and Support Card in SPL was to use
LED for early debugging, but this is not mandatory to boot SoCs.
With this commit, LED will be unavailable in SPL, but we can use a
debug serial instead.  So, this change will not be a big deal.
