Usha P 412679d892 util/ifdtool: Enable CPU read of the ME region
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.

Marcello Sylvester Bauer dc1596c8c8 util/ifdtool: add --output flag
Add an optional commandline flag to define the filename of the resulting
output file. If this flag is not defined, it will behave like before by
using the old filename with a ".new" suffix.

With this additional flag it is not necessary to move the output file at
build-time, and the stdout print "Writing new image to <filename>" makes
more sense in the build context.

Julius Werner 98eeb96135 commonlib: Add commonlib/bsd
This patch creates a new commonlib/bsd subdirectory with a similar
purpose to the existing commonlib, with the difference that all files
under this subdirectory shall be licensed under the BSD-3-Clause license
(or compatible permissive license). The goal is to allow more code to be
shared with libpayload in the future.

Initially, I'm going to move a few files there that have already been
BSD-licensed in the existing commonlib. I am also exracting most
contents of the often-needed <commonlib/helpers.h> as long as they have
either been written by me (and are hereby relicensed) or have an
existing equivalent in BSD-licensed libpayload code. I am also
relicensing <commonlib/compression.h> (written by me) and
<commonlib/compiler.h> (same stuff exists in libpayload).

Finally, I am extracting the cb_err error code definitions from
<types.h> into a new BSD-licensed header so that future commonlib/bsd
code can build upon a common set of error values. I am making the
assumption here that the enum constants and the half-sentence fragments
of documentation next to them by themselves do not meet the threshold of
copyrightability.

Duncan Laurie 7775d67218 ifdtool: Enable GbE/PDR/EC region access only if they exist
Instead of assuming GbE/PDR/EC regions may exist or not, check if there
is a valid region defined in the descriptor and set the region access
permissions based on that.

The net effect change is to enable the use of the PDR region on the
sarien platform, which also uses the GbE and EC regions.

This results in the following example changes:

Bill XIE b3e15a2895 ifdtool: port the feature to set AltMeDisable/HAP bit here
Port the newest feature of me_cleaner to ifdtool
(https://github.com/corna/me_cleaner/ , Discussed in
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.

Routines to dump those bits are also added.

Stefan Tauner 0d22614f46 ifdtool: fix flumap handling in chipsets prior ibex peak/5 series
The Upper Map section in the descriptor contains a database of flash
chips (VSCC Table). Its offset is located at a fixed offset from
the beginning of the image. ifdtool falsely calculates the offset
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.

Furquan Shaikh c0257dd7ae ifdtool: Add a list of known platforms that support IFD_VERSION_2
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.

BUG=b:79109029, b:69270831

Furquan Shaikh 088b6e8f8b util/ifdtool: Fix region access control for SKL/KBL
The default values used by ifdtool for setting region access control
do not match the expected values for SKL/KBL as per the SPI
programming guide. This change adds platform "sklkbl" that sets region
access control bits differently for SKL/KBL images.

BUG=b:76098647
BRANCH=poppy
TEST=Verified that the access control bits on KBL images is set
correctly.
