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.

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

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.

mainboards/amd/fam10: Initialize cbmem area after raminit
When GFXUMA is enabled, CBMEM is placed at TOM - UMASIZE
When GFXUMA is disabled, CBMEM is placed at TOM
This matches the behaviour present before conversion to early
CBMEM.
The CBMEM location code implicitly assumes TOM does not change
between romstage and ramstage. TOM is set by romstage raminit,
and is never changed by romstage or ramstage afterward. As
the CBMEM location is positioned at a specific offset from TOM
that is known to both romstage and ramstage early CBMEM is safe
on Fam10h systems.
TEST: Booted ASUS KFSN4-DRE and verified both cbmem timestamp
tables from romstage and cbmem log tables from ramstage.

The CBMEM memory segment is always placed at TOM - UMASIZE when GFXUMA
is enabled, however when GFXUMA is disabled an attempt was made to locate
the CBMEM memory segment above the I/O hole in certain rare cases.
Removing this special case does not impact functionality, and paves
the way for early CBMEM support.

The AMD RS780 early initialization code originally used the
CF8/CFC I/O method for PCI configuration space access. After
the default configuration access method was changed to MMIO
(http://review.coreboot.org/#q,aad07472), booting would hang
at "PCI: pci_scan_bus for bus 01". Fix the problem by changing
function rs780_nb_gfx_dev_table() so that it no longer borrows
the BAR3 address needed for PCIe MMIO config usage.

The GCC 4.9.2 update showed that the boot_state_init_entry
structures were being padded and assumed to be aligned in to an
increased size. The bootstate scheduler for static entries,
boot_state_schedule_static_entries(), was then calculating the
wrong values within the array. To fix this just use a pointer to
the boot_state_init_entry structure that needs to be scheduled.
In addition to the previous issue noted above, the .bs_init
section was sitting in the read only portion of the image while
the fields within it need to be writable. Also, the
boot_state_schedule_static_entries() was using symbol comparison
to terminate a loop which in C can lead the compiler to always
evaluate the loop at least once since the language spec indicates
no 2 symbols can be the same value.

The current spi_xfer() function sets the count in hardware and then
loops while waiting for the requested number of bytes to be sent or
received. However, the number of bytes to be transferred may exceed
the maximum count that can be programmed into the controller.
This patch re-factors spi_xfer() to split the low-level FIFO handling
portions for transmit/receive into their own functions to be called
by loops in spi_xfer() which will break large transfers into smaller
ones.
