We are implementing a mechanism in coreboot to update CSME firmware,
this requires coreboot to be able to read CSME region. Exposing the
CSME data is not an issue since the data stored by CSE is all encrypted.
This patch provides a command line option "-r" which will enable read
access to CSME region when locking.
Without this change, locking SPI regions using ifdtool will block BIOS
access to read/access CSME. This will cause failure since BIOS can't
read basic information such as CSME version.
TEST=Flashrom returns success while erasing the SI_ME region.
After rebooting the DUT, DUT boots into OS without any issues on
Drawlat EVT.

https://github.com/corna/me_cleaner/issues/53 ) to
set AltMeDisable (or HAP for skylake/ME11) bit to the
IFD to disable ME.
In this commit I use (ifd_version >= IFD_VERSION_2) to
judge whether HAP instead AltMeDisable should be set,
since this condition is only fulfilled on skylake
or newer platforms.
This feature needs to guess ich revision, which needs
guess_ich_chipset() from flashrom to be ported here.

The Upper Map section in the descriptor contains a database of flash

from the descriptor signature which has moved by 16 bytes with
step b of the Ibex Peak (5 series) chipset. This produces bogus
output for all chipsets older than that.
This patch corrects the behavior by calculating the offset of
flumap by adding 4096 - 256 - 4 to the start of the image.

ifdtool has relied on one of the fields within FCBA(read_freq) to
determine whether a platform supports IFD_VERSION_1 or
IFD_VERSION_2. However, newer platforms like GLK and CNL do not have
read_freq field in FCBA and so the value of these bits cannot be used
as an indicator to distinguish IFD versions. In the long run, we need
to re-write ifdtool to have a better mapping of SoC to IFD fields. But
until that is done, this change adds a list of platforms that we know
do not support read_freq field but still use IFD_VERSION_2. This
change also updates GLK and CNL to pass in platform parameter to
ifdtool.

almost certainly aligned, but clang on OSX doesn't like this,
and it's a dicey thing to do in any event, just waiting
to hit someone hard at some future date.
Assign the pointer to a void * and use memmove to copy
the value to a uint32_t.
This usage is more portable to all little-endian architectures,
now, but is still not endian-safe. I doubt we'll ever care.
