Some platforms use tertiary interpretation of GPIO input state to
increase number of distinct values represented by a limited number of
GPIOs. The three states are
- external pull down (interpreted as 0)
- external pull up (1)
- not connected (2)
This has been required by Nvidia devices so far, but Exynos and
Ipq8086 platforms need this too.
This patch moves the function reading the tertiary state into the
library and exposes the necessary GPIO API functions in a new include
file. The functions are still supposed to be provided by platform
specific modules.
The function interpreting the GPIO states has been modified to allow
to interpret the state either as a true tertiary number or as a set
two bit fields.
Since linker garbage collection is not happening when building x86
targets, a new configuration option is being added to include the new
module only when needed.

Add a new utility named bimgtool, a simple tool which generates boot
images in the BIMG format. This is the format the Danube boot ROM
expects the user supplied code to be wrapped in, it is described by
struct bimg_header in the code.
This utility will be used to wrap the coreboot bootblock when building
Danube targets.

What this change does:
1) Initialize limited page tables as soon as we jump into libpayload. Basically
two ranges are initialized. One is for the BASE_ADDRESS and other is for the
coreboot_tables. With page tables initialized and MMU enabled, we jump into
code to parse coreboot tables.
2) Once coreboot tables are parsed and we have complete picture of the memory,
we perform a complete page table initialzation and enable MMU and then jump to
payload.
Additionally, we also:
1) Initialize DMA memory on our own depending upon the memory map. It ensures
that the DMA buffer is placed in 32-bit memory.

The default string functions work with multiple of 4 bytes
(sizeof(unsinged long)); MIPS will use LW/SW instructions
for these operations and if the source and destination
addresses are not aligned it will trigger an exception.
Therefore, this implementation does all data access operations
per byte, because there is no guarantee that the provided
strings are properly aligned.

The correct return value for errors on a cbfs_media->map() call is
CBFS_MEDIA_INVALID_MAP_ADDRESS, not NULL. Not sure if that's the best
choice (since 0xffffffff is probably a more likely valid address than 0
there), but that's what the upper layers expect right now.

TEST=Press CTRL+L with an RW_LEGACY section filled with 0xff. Observe
how cbfs_get_header() returns failure without doing a bunch of NULL
pointer accesses first (not that those have any visible effect on
Veyron, but that's another problem...)

The default mapping size is 1MiB of ram. However, not
all systems allow 1MiB of memory to mapped depending on
the kernel's memory map. Therefore, be explicit about
the sizes to mmap().
The only path that wasn't cleaned up was the coverage path
as that needs to handle dynamic cbmem. The correct way to
fix that is to add a global like the timestamps that is set
while parsing cbtable.

These functions are usually provided by gcc lib, which is not supposed
to be included on embedded platforms. This patch adds a no thrills C
implementation.
Other than MIPS platforms are happy using the gcc library provided

There are three instances of coreboot.c in libpayload. for x86, arm
and arm64 architectures. The arm and arm64 instances are exactly the
same. The differences with the x86 instance are as follows:
- a very slightly different set of coreboot table tags is parsed (one
tag added and two removed)
- instead of checking a fixed address if it contains the coreboot
table, the x86 version iterates over two address ranges.
This patch refactors the module, leaving architecture specific
processing in arch subdirectories and moving the common code into
libc.

Add support to check if the driver for console_out or console_in is already
present in the list. If console_init is called twice, then the driver might get
added twice leading to a loop.
BUG=None
BRANCH=None
TEST=With console_init in libpayload and depthcharge both, there are no console
loops seen anymore

For memalign() requests the current allocator keeps metadata
about each chunk of aligned memory that copmrises the size
requested. For large allocations relative to the alignment
this can cause significant metadata overhead. Instead, consider
all memalign() requests whose size meets or exceeds 1KiB or
alignment that meets or exceeds 1KiB large requests.
These requests are handled specially to only allocate
the amount of memory required for the size and alignment
constraints by not allocating any metadata as the whole region
would be consumed by the request.
BUG=None
BRANCH=None
TEST=Built and tested various scenarios. Noted the ability to
free() and properly coalesce the heap as expected.

Some USB sticks seem to send a NAK at a place where they mustn't
by spec, leading to a controller side error condition.
To avoid it, wait a millisecond which is enough to get past the
NAK condition. That delay only happens on device discovery so it
won't affect boot time by more than 1ms per device.
BUG=chromium:414959
BRANCH=none
TEST=depthcharge recognizes a Lexar 16GB USB stick after applying
this change.

EHCI driver accesses mmio space using regular struct pointers. In order to avoid
any CPU re-ordering, memory barrier is required in async_set_schedule,
especially for arm64. Without the memory barrier, there seems to be re-ordering
taking place which leads to USB errors with some flash drives as well as
transfer errors in netboot.
BUG=chrome-os-partner:31533
BRANCH=None
TEST=With the memory barrier introduced, netboot for ryu completes transfer
without any error and finishes within 6-7 seconds.

Add OpenBSD's header-only implementation of some
basic data structures, imported from
src/sys/sys/queue.h, revision 1.38
(all whitespace errors kept verbatim)
Unlike home-grown solutions they likely handle
all corner cases correctly from the start and
unlike Linux's solution it's properly documented
(see OpenBSD's LIST_INIT(3)) and also BSD-l.
