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).

This is the Intel Minnowboard MAX. It contains an Atom E3800
|
||||
processor in a small form factor with Ethernet, micro-SD, USB 2,
|
||||
USB 3, SATA, serial console, some GPIOs and HDMI 1.3 video out.
|
||||
It requires some binary blobs - see README.x86 for details.
|
||||
|
||||
Note that PCIE_ECAM_BASE is set up by the FSP so the value used
|
||||
by U-Boot matches that value.

This uses as FSP as with Crown Bay, except it is for the Atom E3800 series.

Download this and get the .fd file (BAYTRAIL_FSP_GOLD_003_16-SEP-2014.fd at

the time of writing). Put it in the board directory:

board/intel/minnowmax/fsp.bin

Obtain the VGA RAM (Vga.dat at the time of writing) and put it into the same

directory: board/intel/minnowmax/vga.bin

You still need two more binary blobs. These come from the sample SPI image
|

provided in the FSP (SPI.bin at the time of writing).
|

|

Use ifdtool in the U-Boot tools directory to extract the images from that

file, for example:

If you want to use ELF as the coreboot payload, change U-Boot configuration to

use CONFIG_OF_EMBED instead of CONFIG_OF_SEPARATE.

To enable video you must enable these options in coreboot:

- Set framebuffer graphics resolution (1280x1024 32k-color (1:5:5))
|

- Keep VESA framebuffer

works correctly for link though.
