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.

assembly
In order to ease the process of reading and writing any register at current EL,
provide read_current and write_current assembly macros. These are included in
arch/lib_helpers.h under the __ASSEMBLY__ macro condition. This is done to allow
the same header file to be included by .c and .S files.

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.

Depending on the transport mechanism for proto v3 different bytes
need to be send and/or read before the request and response. Depending
on the software and/or controller interface that requirement leads to
needing to copy data into temporary buffers. Avoid this by allowing
the transport mechanism to provide the request and response
buffers.

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.

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.

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.

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 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.

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.

Provide functionality to create dynamic classes based on program name and the
architecture for which the program needs to be compiled/linked. define_class
takes program_name and arch as its arguments and adds the program_name to
classes-y to create dynamic class and compiler toolset is created for the
specified arch. All the files for this program can then be added to
program_name-y += .. Ensure that define_class is called before any files are
added to the class. Check subdirs-y for order of directory inclusion.
One such example of dynamic class is rmodules. Multiple rmodules can be used
which need to be compiled for different architectures. With dynamic classes,
this is possible.
