In the Quark SoC, some chipset commands are accomplished by utilizing
the internal message network within the host bridge (D0:F0). Accesses
to this network are accomplished by populating the message control
register (MCR), Message Control Register eXtension (MCRX) and the
message data register (MDR).

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).

Since the FSP is a black box it helps to have some sort of debugging

Since these board functions seem to be the same for all boards which use
FSP, move them into a common file. We can adjust this later if future FSPs
need more flexibility.
This creates a generic PCI MMC device.

Rather than requiring the Makefile to be modified, provide a build option to

We cannot do this by default since it requires binary blobs. Without these

In addition to the current Android magic settings, allow to optionally use
DDR3 timing parameters, which are tailored for different clock frequencies
and JEDEC speed bins. This should improve reliability and performance.
Adding '+S:CONFIG_DRAM_TIMINGS_DDR3_1066F_1333H=y' to the board defconfig
allows to use timings, which are calculated for the DDR3-1066F speed bin.
A lot of DDR3 chips, which are used in real Allwinner based devices,
support DDR3-1066F speed bin timings.
And adding '+S:CONFIG_DRAM_TIMINGS_DDR3_800E_1066G_1333J=y' should work
with any DDR3 chips, because this targets the slowest JEDEC speed bins.
The vendor magic values are still used by default for DRAM, but board
maintainers now have more flexibility in DRAM timings selection.

On both my A13-OLinuxIno and my A13-OLinuxIno-Micro, the vga output gives an
unstable image when active low v or hsync is used.
The problem seems to be specific to the OLinuxIno A13 (normal & micro)
boards. I've just looked up the schematics and they use an opendrain driver
for the vga sync lines, and with sync pulses it is the logical high->low
edge of the pulse which counts for the timing, which with an active low
sync is being driven by the pull-up, and that simply seems to not drive
it hard enough to get a stable image.
So force v and hsync active high on these boards. independent of what the
modeline says. This fixes the unstable image.

This is a low-cost Allwinner A20 board with Arduino-style GPIO headers;
it features 1G RAM, 4G NAND flash, 1 micro-SD, 2 USB sockets, 1 micro
USB socket for OTG and another for power in, HDMI, SATA, 5V power for
SATA devices, gigabit Ethernet, an IR receiver, 3.5mm audio out and a
MIPI camera connector.
Like the BananaPi, this board needs GMAC_TX_DELAY set to 3 in order for
GMAC to work reliably at gigabit speeds.
