f9d275b2bd x86: dts: Mark serial as needed before relocation
We almost always need the serial port before relocation, so mark it as such.
This will ensure that it appears in the device tree for SPL, if used.

3a1a18ff18 x86: Add support for Intel Minnowboard Max
This is a relatively low-cost x86 board in a small form factor. The main
peripherals are uSD, USB, HDMI, Ethernet and SATA. It uses an Atom 3800
series CPU. So far only the dual core 2GB variant is supported.

This uses the existing FSP support. Binary blobs are required to make this
board work. The microcode update is included as a patch (all 3000 lines of
it).

1eb47efc49 x86: Use ePAPR defined properties for x86-uart
Use ePAPR defined properties for x86-uart: clock-frequency and
current-speed. Assign the value of clock-frequency in device tree
to plat->clock of x86-uart instead of using hardcoded number.

9ca5a0ca0e x86: Rename coreboot.dsti to serial.dtsi
The name of coreboot.dtsi is misleading, as it actually describes
the legacy serial port device node.
