Some parts of lbmk set +u +e, to be reset later on
under normal conditions upon exit. We must ensure
such level of integrity in err() as well.

Rely once again on err_, but still explicitly add an exit
just below, in case I made a mistake one day.
err() is essentially a trap that triggers in case I mess
up an error function, so that it doesn't reliably exit.
So, the idea is that everything calls err(), and err() is
almost never modified, or modified very carefully.
If error exits were ever broken, the result could be quite
unpredictable, so lbmk has very strict error handling, and
great care is taken to ensure that it does reliably exit.

make the command style more consistent, for example
relying on x_ inside a subshell to print the command
and arguments if a command failed.
this is a good style, and i'll probably use it in other
places on lbmk.

Don't directly call a variable. Call a function that
checks the variable instead.
The new err function also checks whether an exit was
actually done, and exits 1 if not.
If an exit was done by the given function, but the exit
was zero, this is also corrected to perform an exit 1.
This fixes a longstanding design flaw of lbmk.

Always certainly redundant, since if -u -e isn't
set, it'll continue to exit anyway.
However, we want to be pedantic about this, since
the safety of lbmk relies entirely on this function
NOT misbehaving.

we know that _dest is always what's set in the coreboot config,
without the ../../../ in it, so just copy both files in a single
function, and call the function twice.
if both files are done on the first call, the second call will
be skipped. if only the first file was done on the first call,
running the download script again will skip the first one, and
grab the second one.
this also avoids having to run the decat function twice, in most
cases, so it's a tiny optimisation.
this optimisation only works if both fsp files (s and m) are to
be extracted into the same directory, which is the case anyway,
and this will always be the case.

Don't copy it until it has been padded properly.
Otherwise, erroneous padding would result in an error,
and who knows what would be left in vendorfiles/ ?

If we're in a release work directory, TMPDIR is already
set, so the local ./tmp won't be created, which would
lead to an error.
Fix it by creating xbmklocal before checking TMPDIR.

this silences confusing error messages that the user
sees on the screen, that are actually benign, and it
will thus reduce the number of people who ask questions

it's not a lot of code, and takes less than a second.
the previous change uses x instead of ?, but this would
cause an error if the nvmutil was already built, because
the makefile might cause a build to be skipped.
therefore, force a re-build to mitigate the error.

A user reported that '?' causes an error on zsh. See:
https://codeberg.org/libreboot/lbmk/issues/261
For example:
./mk inject libreboot-XXXXXX.tar.xz setmac ??:??:??:??:??:??
The user got:
zsh: no matches found: ??:??:??:??:??:??
The mitigation here is to double-quote, e.g.:
./mk inject libreboot-XXXXXX.tar.xz setmac "??:??:??:??:??:??"
However, a lot of people won't do that. Therefore, I will
retain the current behaviour but support x/X for randomness.
Now lbmk uses x by default, instead. I will now update the
documentation, accordingly.

not to be confused with /tmp
we use ./tmp inside the lbmk work directory, for large files,
because /tmp might not be very big, or might be a tmpfs

In the mk script, we need fx_ to not return errors on the
find command, since it's searching a bunch of directories
where some of them may not exist.
All other instances where fx_ is used, must return an error
if the directory being searched doesn't exist.
For this, fe_() is introduced, which does the same as fx_
but with this much stricter check.
Signed-off-by: Leah Rowe <leah@libreboot.org>
We have a lot of places in lbmk where the output of find is
used, and then some function is executed on the result.
This is messy, and bloats several of these functions.
Now this is unified, into a new function: fx_
What fx_ does is execute a given function, for each result
found, with the arguments for a find command appended.
For example:
find -name ".git"
If you wanted to do: foo "$arg"
Where "arg" is a search result from find, and you wanted
to execute "foo" on each one, you would do:
fx_ foo -name ".git"
The find utility does have an -exec feature, but I've found
that it only works for executables, not functions.
fx_ does not return errors, so "foo" in this example
would have to do its own error handling.

This is similar to the 9020SFF, but this board has ECC support.
However, the native raminit isn't used here, even though it is
otherwise compatible, because the native init doesn't do ECC yet.
The broadwell mrc.bin has ECC support, which is also used on the
HP EliteBook 820 G2. The MRC for broadwell can be used on haswell
boards such as the T1700.
Add both the SFF and MT variants. Since these are identical to the
9020 variants, except for slightly different PCH enabling ECC, we
can just re-use the 9020 port without issue.
We *could* add a variant to coreboot, for T1700, but there is not
really any pressing need. It is simply the 9020sff/mt with mrc.bin
