This fixes a SEGFAULT if a layout entry is included that addresses memory
outside the current chip's address range. flashrom will only abort if the
offending region(s) is/are included else it will just warn.
It will print warnings for regions with negative or zero-length address ranges
and bail out after checking all of them.
Also, abort for non-write operations if a layout file is given because there is
no layout support for other operations yet.

Do not rely on broken firmware to set up the SPI configuration correctly.
Some boards fail with flashrom because the firmware chose too high speeds
for the alternate SPI mode which flashrom uses. Temporarily change the

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.

I broke this in r1702 where I enabled avoidance of the verification step if
we did not modify anything in the erase/write step. The problem is that
all_skipped is initialized to true and hence it would only ever verify if
there have been changes noted in the erase/write step. This obviously
breaks the verification operation (-v/--verify) because there we never
enter the erase/write loop.
The better alternative would be to enable (the implicit) verification
in the write loop and not in cli_classic.c. This would require a bigger
change due to the existance of dont_verify_it. Eventually this is the
right thing to do but not so shortly before a release.
