Sergii Dmytruk 6da62684de util/cbmem: add parsing of TPM logs per specs
CBMEM can contain log in different forms (at most one is present):
 - coreboot-specific format (CBMEM_ID_TPM_CB_LOG exported as
   LB_TAG_TPM_CB_LOG)
 - TPM1.2 format (CBMEM_ID_TCPA_TCG_LOG)
 - TPM2 format (CBMEM_ID_TPM2_TCG_LOG)

The last two follow specifications by Trusted Computing Group, but until
now cbmem couldn't print them.  These formats were added not so long ago
in:
 - commit 4191dbf0c9 ("security/tpm: add TPM log format as per 1.2
   spec")
 - commit 53db677586 ("security/tpm: add TPM log format as per 2.0
   spec")

These changes make cbmem utility check for existence of TPM1.2/TPM2 logs
in CBMEM and add code necessary for parsing and printing of their
entries.

Werner Zeh 1c727fd784 util/cbmem: Provide a way to override coreboot path
Right now cbmem uses a fix path to reach coreboot src path (../../).
This makes it impossible to compile cbmem out of the coreboot tree (e.g.
copy just the cbmem directory elsewhere and compile).

This patch adapts the technique from cbfstool and adds a variable called
'TOP' which points to coreboot root directory and which can be
overridden at build time by providing it to make as an argument. This
will enable a stand-alone build of cbmem.

Bora Guvendik c79da5f211 util/cbmem: Keep original Total Time calculation when no negative timestamps
"Total time" calculation changed after CL 59555 to include
"1st timestamp" value in the calculation. This patch restores original
Total Time calculation where "1st timetamp" is subtracted from
"jumping to kernel". If pre CPU reset timestamps are added (negative
timestamps), "Total time" calculation still includes the pre-reset time
as expected.

   0:1st timestamp                                     225,897

Julius Werner ce87832c66 cbmem: Fix console banner matches
Since the new loglevel markers were added, there will now be a marker
character at the beginning of the coreboot banner string, and this will
make the existing regular expressions meant to find it fail to match.
This patch fixes the problem by just allowing for a single extra
character there (any character to avoid the hassle of having to match
the marker explicitly). The extra character is optional so that we will
still continue to match banners from older versions of coreboot as well.

Since the `?` glyph is not available in basic POSIX regular expressions,
we have to switch to REG_EXTENDED syntax (should otherwise make no
difference). (Also, move side effects out of assert() while I'm here,
that's not actually safe for the standard libc implementation.)

Julius Werner b8258bd2b9 util/cbmem: Add --loglevel option to restrict console printing by level
This patch adds a new --loglevel option to the CBMEM utility which can
be used either numerically (e.g. `cbmem -1 --loglevel 6`) or by name
(e.g. `cbmem -c --loglevel INFO`) to restrict the lines that will be
printed from the CBMEM console log to a maximum loglevel. By default,
using this option means that lines without a loglevel (which usually
happens when payloads or other non-coreboot components add their own
logs to the CBMEM console) will not be printed. Prefixing a `+`
character to the option value (e.g. `--loglevel +6` or
`--loglevel +INFO`) can be used to change that behavior.

Julius Werner 984d03c492 console: Add loglevel marker codes to stored consoles
In order to provide the same loglevel prefixes and highlighting that
were recently introduced for "interactive" consoles (e.g. UART) to
"stored" consoles (e.g. CBMEM) but minimize the amont of extra storage
space wasted on this info, this patch will write a 1-byte control
character marker indicating the loglevel to the start of every line
logged in those consoles. The `cbmem` utility will then interpret those
markers and translate them back into loglevel prefixes and escape
sequences as needed.

Since coreboot and userspace log readers aren't always in sync,
occasionally an older reader may come across these markers and not know
how to interpret them... but that should usually be fine, as the range
chosen contains non-printable ASCII characters that normally have no
effect on the terminal. At worst the outdated reader would display one
garbled character at the start of every line which isn't that bad.
(Older versions of the `cbmem` utility will translate non-printable
characters into `?` question marks.)

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.

Raul E Rangel d4fec689fd cbmem: Sort timestamp entries
If the timestamp entries are added out of order, the duration
calculation will be wrong.

AGESA collects timestamp data through all the stages. Then in AmdInitPost
it asks for a buffer to write TP_Perf_STRUCT into. agesawrapper will then
take the data and call timestamp_add on each entry. This results in
the entries being out of order.

TEST=Built firmware for grunt that manually added entries and then ran
cbmem -t/-T to verify the entries were in the correct order.

Furquan Shaikh 35972def1d util/cbmem: Re-order regex for "cbmem -1"
In case of console dump for only the last boot, cbmem utility checks
for a list of regex in provided order. When pre-cbmem console
overflows, "Pre-CBMEM <stage> console overflowed.. " message is added
before "... <stage> starting" message. This change fixes the order of
regex in cbmem utility to match this.

Test=Verified on soraka that "cbmem -1" correctly dumps the data
starting from Pre-CBMEM romstage overflowed.
