We do CPU architecture checks once for the makefile in arch.h and
once for HW access abstraction in hwaccess.c. This patch unifies
related files so that they can share the checks to improve
maintainability and reduce the chance of inconsistencies.
Furthermore, it refines some of the definitions, which
 - adds "support" for AARCH64 and PPC64,
 - adds big-endian handling on arm as well as LE handling on PPC64,
 - fixes compilation of internal.c on AARCH64 and PPC64.

Additionally, this patch continues to unify all OS checks in
flashrom by adding a new helper macro IS_WINDOWS.

The old header file for architecture checking is renamed to platform.h
to reflect its broader scope and all new macros are add in there.

Up to now, when compiling flashrom outside a VCS it would print two
warnings that are not very clear to the user. This patch adds a new
auxilary function to getrevision.sh and uses it in the makefile to print a
single and more meaningful message to the user while hiding the
warnings from getrevision.sh.

Basically, among other chips, MSTAR manufactures SoCs that equip TV sets
and computer screens, and it seems that all of their products use the
same in-system programming protocol. Basically, they use the DDC channel
of VGA or DVI connectors, which is actually an I2C bus, to encapsulate
SPI frames (the flash chip is connected to the SoC through an SPI bus).

I wrote this patch since the screen I bought had a software bug, and the
manufacturer only released a new firmware binary, but no tool or
instructions on flashing it.

More details can be found here:
http://boeglin.org/blog/index.php?entry=Flashing-a-BenQ-Z-series-for-free(dom)



I only read code from Linux kernel archives published by Acer to figure
out the protocol (for a touchscreen controller and an NFC chip, both by
MSTAR, that share the same ISP protocol), so I don't think there are
any legal problems with it.

Compilation is currently disabled by default in the Makefile.
If in doubt, additional Makefile bugs were added by Stefan.

Some Parallel bus chips have a 16-bit mode and an 8-bit mode. They use
normal JEDEC addresses for 16-bit mode and shifted addresses (by 1 bit)
for 8-bit mode. Some programmers can access them in 16-bit mode, but on
all flashrom-supported programmers so far, we access them in 8-bit mode.
This means we have to shift the addresses but apart from the addresses
we can share the code.

This patch makes this possible by checking the chip's FEATURE_ADDR_SHIFTED
flag in common JEDEC functions and applying the right addresses respectively.

This patch lets you read and write the EEPROM on 82580-based gigabit NIC

and labelled as:

Previously we had to rely on dmidecode to decode the DMI/SMBIOS table.
This patch integrates a DMI decoder into flashrom. The old behavior of calling
dmidecode can be brought back by using CONFIG_INTERNAL_DMI=no.

Significant portions of this patch were taken from dmidecode, hence add its
authors to the copyright notice (dmidecode is also GPL2+). We do a few things
differently though. First of all we do more bounds checking to prevent accessing
unmapped memory. We do not support disovery via EFI (yet), but memory
scanning only. We handle the chassis-type lock bit correctly which dmidecode
did not for a long while.

The API to the rest of flashrom remains stable, but the output changes slightly.
To share as much code as possible (which actually is not much), i have added
dmi_fill methods that get called in dmi_init. They are reponsible to fill the
dmi_strings array and setting the is_laptop variable. After it is called, dmi_init
prints all dmi_strings. Previously the strings were printed in the order they were
discovered, followed by the chassis-type, which is now output earlier (in dmi_fill).

Because DJGPP does not support strnlen a simple implementation was added
for it.

This is still only available on x86; actually it is not even compiled in for other
architectures at all anymore.

Flashrom won't build nor run as native payload very soon (or ever).
This patch changes a special GNU make variable that allows to select
the default goal which is taken if no goal is given explicitly on
the command line. Normally this would be the first rule in Makefile,
i.e. all. This won't compile if the target OS is libpayload, hence
change it to "libflashrom.a" in that case.

This requires two not completely ancient GNU make features:
 - MAKECMDGOALS
 - .DEFAULT_GOAL

Checking for these with ancient-only GNU make features is non-trivial
and hereby postponed.

GNU make has a very interesting quirk: If you set a variable on the
command line, any changes to that variable in the Makefile are ignored
unless marked with the "override" keyword.

Use CFLAGS only for optimization and warning options, and use CPPFLAGS
for the dependency and other preprocessor related options.
That way packagers can specify their own CFLAGS without breaking the
build.

As a side benefit, the ich_descriptors_tool Makefile now behaves exactly
the same whether called standalone or as part of the main Makefile.
