xHCI requires special treatment of set_address since it determines
the device number itself (instead of the driver, as with the other
controllers). The controller also wants to validate a chosen device
configuration and we need to setup additional structures for the
device and the endpoints.
Therefore, we add three functions to the hci_t structure, namely:
set_address()
finish_device_config()
destroy_device()
Current implementation for the Set Address request moved into
generic_set_address() which is set_address() for the UHCI, OCHI and
EHCI drivers. The latter two are only provided as hooks for the xHCI
driver.
The Set Configuration request is moved after endpoint enumeration.
For all other controller drivers nothing changes, as there is no other
device communication between the lines where the set_configuration()
call moved.

This issue can be reproduced in Linux by the following steps:
1) use pm-suspend to suspend.
2) use USB keyboard to wake up.
3) use pm-suspend to suspend. FAIL To SUSPEND.
The cause of this issue is:
USB devices use bit 11(0x0b) of GP0_STS represents S3 wake up event,
but this bit is not clear after wake up. So OS thinks there is a
wake up signal and wake up immediately.
In this patch, I add AcpiGpe0Blk using MMIO access and write 1
on bit 11. Write 1 to clear as spec says.
I have tested on Thatcher

Loading on an OMAP SOC requires that the first sector of the image have a
configuration header, and, when not an execute in place image, an additional
header which describes how big the image is and where it should be loaded.
This change adds some infrastructure to statically build that header using C
code, and to paste the header onto the front of coreboot.rom in a new top
level target file called MLO.
The configuration header we're using is as inert as possible, in line with
what U-Boot is doing. I think it could be used to give additional
configuration parameters to the built-in ROM on the SOC, but we don't need to
do that, and there didn't seem to be any actual documentation how to do that.
Because the header is built from C and is defined per CPU, it would be
possible to include extra settings in other CPUs if desired.
Adding a new top level build target is a bit disruptive, but should be
contained to the am335x directory and not interfere with other mainboards.

On ARM, there's frequently some firmware built into the SOC which runs
first and which loads other firmware like Coreboot from some other
media. To prevent the bootblock from having to know how to find and load
the ROM stage from what may be a complicated source (sd card,
netbooting, etc.), we can put the ROM stage immediately after the
bootblock and ensure that they're both loaded at the same time.
This change adjusts the Makefile.inc for ARM so that the ROM stage is put
into the image before any other files so that we know it comes first.
This changes the behavior of the CONFIG_UPDATE_IMAGE config option used
by abuild, although it's not entirely clear whether that's still used.

(ASL). These functions are used to control embedded controllers with the
standard ACPI interface (mostly through i/o ports 0x62 / 0x66).
The following methods are implemented and tested against the power
managements channels of a ITE IT8516E embedded controller:
* WAIT_EC_SC Wait for a bit in the EC_SC register
* SEND_EC_COMMAND Send one command byte to the EC_SC register
* SEND_EC_DATA Send one data byte to the EC_DATA register
* RECV_EC_DATA Read one byte of data from the EC_DATA register
* EC_READ Read one byte from ec memory (through cmd 0x80)
* EC_WRITE Write one byte to ec memory (through cmd 0x81)
To use the provided methods, one should include `ec/acpi/ec.asl` in the
EC device code. Prior doing so, two macros should be defined to identify
the used i/o ports:
* EC_SC_IO I/o address of the EC_SC register
* EC_DATA_IO I/o address of the EC_DATA register

The DDI connector table and the PCIe Port List lookup table are
copied onto HEAP. This copy is not needed since these are lookup
tables used to define the platform configuration.

Add CONST modifiers to read-only pass-by-reference function
parameters in AGESA. This allows the use of "const" modifiers
on the declaration of lookup tables that are pass-by-reference.
These will be used to identify tables that are copied onto the
HEAP but don't need to be.

Add boot cpu to the device tree. Figure the number of CPUs installed
(using the qemu firmware config interface) and add cpu devices for them,
so they show up in all generated BIOS tables correctly. This gets SMP
going.

This patch adds a qemu x86 cpu chip. It has no initialization function
as this isn't needed on virtual hardware. A virtual machine can have
pretty much any CPU: qemu emulates a wide range of x86 CPUs (try 'qemu
-cpu ? for a list), also with 'qemu -cpu host' the guest will see a cpu
which is (almost) identical to the one on the host machine. So I've
added X86_VENDOR_ANY as wildcard match for the cpu_table.
