* x86: Add DFI BT700 BayTrail board supportStefan Roese2016-08-16-0/+4
| | | | | | | | | | This patch adds support for the DFI BayTrail BT700 QSeven SoM installed on the DFI Q7X-151 baseboard. The baseboard is equipped with the Nuvoton NCT6102D Super IO chip providing the UART as console.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for Advantech SOM-DB5800 with the SOM-6867 installed. This is very similar to conga-qeval20-qa3-e3845 in that there is a reference carrier board (SOM-DB5800) with a Baytrail based SoM (SOM-6867) installed.

| | | | | | | | | | | | | | | CONFIG_GENENRATE_ACPI_TABLE controls the generation of ACPI table which uses U-Boot's built-in methods and CONFIG_QEMU_ACPI_TABLE controls whether to load ACPI table from QEMU's fw_cfg interface. But with commit "697ec431469ce0a4c2fc2c02d8685d907491af84 x86: qemu: Drop our own ACPI implementation", there is only one way to support ACPI table for QEMU targets which is the fw_cfg interface.

| | | | | | | | | | | | | | | SeaBIOS is an open source implementation of a 16-bit x86 BIOS. It can run in an emulator or natively on x86 hardware with the use of coreboot. With SeaBIOS's help, we can boot some OSes that require 16-bit BIOS services like Windows/DOS. As U-Boot, we have to manually create a table where SeaBIOS gets system information (eg: E820) from. The table unfortunately has to follow the coreboot table format as SeaBIOS currently supports booting as a coreboot payload.

* x86: fsp: Make sure HOB list is not overwritten by U-BootBin Meng2016-02-21-0/+10
| | | | | | | | | | | | | | | | | | | | | Intel IvyBridge FSP seems to be buggy that it does not report memory used by FSP itself as reserved in the resource descriptor HOB. The FSP specification does not describe how resource descriptor HOBs are generated by the FSP to describe what memory regions. It looks newer FSPs like Queensbay and BayTrail do not have such issue. This causes U-Boot relocation overwrites the important boot service data which is used by FSP, and the subsequent call to fsp_notify() will fail. To resolve this, we find out the lowest memory base address allocated by FSP for the boot service data when walking through the HOB list in fsp_get_usable_lowmem_top(). Check whether the memory top address is below the FSP HOB list, and if not, use the lowest memory base address allocated by FSP as the memory top address.

Use a Kconfig option GENERATE_MP_TABLE to tell U-Boot whether we need actually write the MP table at the F seg, just like we did for PIRQ routing and SFI tables. With MP table existence, linux kernel will switch to I/O APIC and local APIC to process all the peripheral interrupts instead of 8259 PICs.
