When passing '-ffreestanding' the 'main' romstage.c may no longer
necessarily be considered the entry point.
From the C specification in 5.1.2.1 Freestanding environment;
"In a freestanding environment (in which C program execution may take
place without any benefit of an operating system), the name and type of
the function called at program startup are implementation-defined."
Clang complains about these being missing as Clang is somewhat more
strict about the spec than GNU/GCC is. An advantage here is that a
different entry-point type-signature shall now be warned about at
compile time.

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.

There are three coreboot table tags that all define some kind of memory
region, and each has their own homologous struct. I'm about to add a
fourth so I'll just clean this up and turn it into a generic struct
lb_range instead.

Unfortunately coreboot has to deal with ROMCC's short comings which has
lead to a little bit of confusion due to typedefs. Essentially, coreboot
defines four typedefs:
* 'typedef struct device * device_t' in ramstage not in SIMPLE_DEVICE mode
* 'typedef u32 device_t' in romstage or when SIMPLE_DEVICE is defined
* 'typedef u32 pnp_devfn_t'
* 'typedef u32 pci_devfn_t'
Some early functions make use of 'device_t' over 'pci_devfn_t' and since
the C type-checker does not enforce typedefs to the same type 'u32'
these are never noticed. Fix these so that 'device_t' does not conflict
in romstage for later work. We later plan to have 'pnp_devfn_t' and
'pci_devfn_t' as the only variants of 'u32' and 'device_t' to be a
struct pointer type exclusively.

Whenever spi_xfer is called and whenver it's implemented, the natural unit for
the amount of data being transfered is bytes. The API expected things to be

The PCI Specification states that devices that implement
a bridge and a secondary bus must swizzle (rotate) the
interrupt pins according to the table below:
Child Dev # Child PIN Parent PIN
0,4,8,12... A/B/C/D A/B/C/D
1,5,9,13... A/B/C/D B/C/D/A
2,6,10,14.. A/B/C/D C/D/A/B
3,7,11,15.. A/B/C/D D/A/B/C
Which is also described by this equation:
PIN_parent = (Pin_child + Dev_child) % 4
When a device is found and its bus number is greater than 0,
it is on a bridge and needs to be swizzled. Following the
string of parents up to the root bus and swizzling as we go
gives us the desired swizzling result. When BIOS_SPEW is
defined, it will print out each step of the swizzling process.

The reg_script library has proven to be useful. It's
also shown that many scripts operate on devices. However,
certain code paths run the same script on multiple,
but different, devices. In order to make that easier
introduce reg_script_run_on_dev() which takes a device
as a parameter. That way, chained reg_scripts are not
scrictly needed to run the same script on multiple devices.

Make all three coreboot stages (bootblock, romstage and ramstage) aware of the
architecture specific to that stage i.e. we will have CONFIG_ARCH variables for
each of the three stages. This allows us to have an SOC with any combination of
architectures and thus every stage can be made to run on a completely different
architecture independent of others. Thus, bootblock can have an x86 arch whereas
romstage and ramstage can have arm32 and arm64 arch respectively. These stage
specific CONFIG_ARCH_ variables enable us to select the proper set of toolchain
and compiler flags for every stage.
These options can be considered as either arch or modes eg: x86 running in
different modes or ARM having different arch types (v4, v7, v8). We have got rid
of the original CONFIG_ARCH option completely as every stage can have any
architecture of its own. Thus, almost all the components of coreboot are
identified as being part of one of the three stages (bootblock, romstage or
ramstage). The components which cannot be classified as such e.g. smm, rmodules
can have their own compiler toolset which is for now set to *_i386. Hence, all
special classes are treated in a similar way and the compiler toolset is defined
using create_class_compiler defined in Makefile.
In order to meet these requirements, changes have been made to CC, LD, OBJCOPY
and family to add CC_bootblock, CC_romstage, CC_ramstage and similarly others.
Additionally, CC_x86_32 and CC_armv7 handle all the special classes. All the
toolsets are defined using create_class_compiler.
Few additional macros have been introduced to identify the class to be used at
various points, e.g.: CC_$(class) derives the $(class) part from the name of
the stage being compiled.
We have also got rid of COREBOOT_COMPILER, COREBOOT_ASSEMBLER and COREBOOT_LINKER
as they do not make any sense for coreboot as a whole. All these attributes are
associated with each of the stages.

Since the header is not compiled and linked together

the symbol used for knowing the entry point. There
was a little churn in SMM modules to ensure an

Boot speeds can be sped up by mirroring the payload into
main memory before doing the actual loading. Systems that
would benefit from this are typically Intel ones whose SPI
are memory mapped. Without the SPI being cached all accesses
to the payload in SPI while being loaded result in uncacheable
accesses. Instead take advantage of the on-board SPI controller
which has an internal cache and prefetcher by copying 64-byte
cachelines using 32-bit word copies.

Divisor is a function of requested baudrate, platform-specific
reference clock and amount of oversampling done on the UART reference.
Calculate this parameter with divisor rounded to nearest integer.
When building without option_table or when there is no entry for
baud_rate, CONFIG_TTYS0_BAUD is used for default baudrate.
For OxPCIe use of 4 MHz for reference was arbitrary giving correct
divisor for 115200 but somewhat inaccurate for lower baudrates.
Actual hardware is 62500000 with 16 times oversampling.
FIXME: Field for baudrate in lb_tables is still incorrect.

out to a bootmem memory map. The bootmem concept can then be

With the recent improvement 3d6ffe76f8a505c2dff5d5c6146da3d63dad6e82,
speedup by CACHE_ROM is reduced a lot.
On the other hand this makes coreboot run out of MTRRs depending on
system configuration, hence screwing up I/O access and cache
coherency in worst cases.
CACHE_ROM requires the user to sanity check their boot output because
the feature is brittle. The working configuration is dependent on I/O
hole size, ram size, and chipset. Because of this the current
implementation can leave a system configured in an inconsistent state
leading to unexpected results such as poor performance and/or
inconsistent cache-coherency
Remove this as a buggy feature until we figure out how to do it properly
if necessary.

Certain CPUs require the default SMM region to be backed up
on resume after a suspend. The reason is that in order to
relocate the SMM region the default SMM region has to be used.
As coreboot is unaware of how that memory is used it needs to
be backed up. Therefore provide a common method for doing this.

There are 2 methods currently available in coreboot to load
ramstage from romstage: cbfs and vboot. The vboot path had
to be explicitly enabled and code needed to be added to
each chipset to support both. Additionally, many of the paths
were duplicated between the two. An additional complication
is the presence of having a relocatable ramstage which creates
another path with duplication.
To rectify this situation provide a common API through the
use of a callback to load the ramstage. The rest of the
existing logic to handle all the various cases is put in
a common place.
