Coreboot has all necessary infrastructure to use the proper SPI flash
interface in bootblock for CBFS. This patch creates a common CBFS
wrapper which can be enabled on different platforms as required.
COMMON_CBFS_SPI_WRAPPER, a new configuration option, enables the
common CBFS interface and prevents default inclusion of all SPI chip
drivers, only explicitly configured ones will be included when the new
feature is enabled. Since the wrapper uses the same driver at all
stages, enabling the new feature will also make it necessary to
include the SPI chip drivers in bootblock and romstage images.
init_default_cbfs_media() can now be common for different platforms,
and as such is defined in the library.
BUG=none
TEST=manual
. with this change and the rest of the patches coreboot on AP148
comes up all the way to attempting to boot the payload (reading
earlier stages from the SPI flash along the way).

To support parsing multiple EDID blobs, the static "decode results" flags should
be changed to auto variables inside decode_edid.
This is done by packaging static variables into a structure inside decode_edid.
We also revised some functions (manufacturer_name, do_checksum) to avoid
accessing global variables directly. Extension (and detail block) parsing may
need to access and return all parsed context so we pass the whole structure to
it.

predictable place relative to other things in the linker script. That makes it
difficult to work with as its own section because the linker will complain if
you try to move backwards as it lays out memory. If the console header is
treated as an actual blob of memory which has to be put in the image, we'd
have to predict where to put it so that it isn't before something with a lower
address or after something with a higher address. Symbols, on the other hand,

This patch adds stub implementations of exception_init() to all archs
so that it can be called from src/lib/hardwaremain.c. It also moves/adds
all other invocations of exception_init() (which needs to be rerun in
every stage) close to console_init(), in the hopes that it will be less
likely overlooked when creating future boards. Also added (an
ineffective) one to the armv4 bootblock implementations for consistency
and in case we want to implement it later.

Peppy had some issues with FUI. We decided it was time to create
peppy-specific gma.c and i915io.c files. Using yabel and the i915tool,
we generated a replay attack, then interpolated against the slippy
i915io.c to get something working.
Also, in preparation for moving code out of the mainboard gma.c to
generic driver code, we got rid of some hardcodes in the mainboard
gma.c that have no business being there. The worst were the
computation of gmch_[m,n] and it turns out that we had some
long-standing bugs related to confusion about 'bpp'. I've killed the
word bpp everywhere I could because there are at least 3 things that
correspond to bpp. We now have framebuffer, pipe, and panel bpp. The
names are long because I want to avoid all the mistakes we've all been
making in the last year :-) Sadly, that means a lot of changes not just
peppy-related, but they are simple and in a good cause.
The test pattern generation is driven by a global variable in
mainboard/peppy/gma.c. I've found in the past that it's very useful
to have a function like this available, as one can activate it while
using a jtag debugger: halt at the right place in ramstage, set the
variable to 1, continue. It's not enough code to worry about always
including.
The last hard-codes for M and N registers are gone, and the function
to set from generic intel_dp.c code works. To avoid screen trash on a
dev mode boot, which we liked but nobody else did :-), we now take the
time to put a pleasing background color that sort of doubles as a
power LED.
Rough timing is ramstage start is at 2.2, and dev setup is done at
3.3. These new platforms are depressingly slow to boot. Rom init alone
is taking 1.9 seconds. 13 years ago it was 3 seconds from power on to bash
prompt. These CPUs are at least 10x faster and take much longer to get going.
Future work, once we get this through, is to move more functions to the
intel driver, and combine the mainboard i915io.c into the mainboard gma.c.
That separation only existed because i915io.c was generated by a tool, and it
had lots of ugliness. Most ugliness is gone.

Some drivers (like the I2C TPM driver) call mdelay instead of
udelay. While it's a shame that these chips are so slow, the
overhead of having those functions available in romstage is
minimal.

This patch adds a mechanism to set aside a region of cache-coherent
(i.e. usually uncached) virtual memory, which can be used to communicate
with DMA devices without automatic cache snooping (common on ARM)
without the need of explicit flush/invalidation instructions in the
driver code.
This works by setting aside said region in the (board-specific) page
table setup, as exemplary done in this patch for the Snow and Pit
boards. It uses a new mechanism for adding board-specific Coreboot table
entries to describe this region in an entry with the LB_DMA tag.
Libpayload's memory allocator is enhanced to be able to operate on
distinct types/regions of memory. It provides dma_malloc() and
dma_memalign() functions for use in drivers, which by default just
operate on the same heap as their traditional counterparts. However, if
the Coreboot table parsing code finds a CB_DMA section, further requests
through the dma_xxx() functions will return memory from the region
described therein instead.

Provide functionality to create dynamic classes based on program name and
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. Also, 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.

The CBFS core checks the result of a media->map() operation in multiple
places for CBFS_MEDIA_INVALID_MAP_ADDRESS, suggesting that this is a
valid response. However, it ironically fails to do so when actually
mapping the CBFS file itself, which can fail on buffer-constrained
systems since the size is much larger than when mapping metadata. This
patch adds a check with an error message and a NULL pointer return for
that case to make it easier to understand this condition.
