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).

x86: baytrail: Support operation as an EFI payload Disable a few things which interfere with the EFI init. This allows the Minnowboard MAX to boot into EFI, load a U-Boot payload then boot to the U-Boot prompt. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

x86: baytrail: Introduce a Kconfig option for the internal UART There are quite a number of BayTrail boards that uses an external SuperIO chipset to provide the legacy UART. For such cases, it's 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.

if INTEL_BAYTRAIL
config INTERNAL_UART
bool "Enable the SoC integrated legacy UART"
help
There is a legacy UART integrated into the Bay Trail SoC.
A maximum baud rate of 115200 bps is supported. For this
reason, it is recommended that the UART port be used for
debug purposes only, eg: U-Boot console.
x86: baytrail: Fix boot hang with a debug build It was observed that when -DDEBUG is used to generate a debug build, U-Boot does not boot on MinnowMax board. A workaround is to disable CONFIG_DEBUG_UART. The real issue is that in order to have the debug uart to work, BayTrail SoC needs to be configured so that its internal uart is available to be used as the debug uart.
