haswell: only provide NRI-based ROMs in releases release="n" is set in target.cfg on haswell build targets that use mrc.bin script/update/release exports LBMK_RELEASE="y" script/build/roms skips building a given target if release="n" in target.cfg *and* LBMK_RELEASE="y" you could also do the export yourself before running ./build roms, for example: export LBMK_RELEASE="y" ./build roms all This would skip these ROM images. The native haswell raminit is now stable enough in my testing, that I wish to delete the MRC-based targets. This is in line with Libreboot's Binary Blob Reduction Policy, which states: if a blob can be avoided, it should be avoided. The problem is that users often run the inject script in *lbmk* from Git, instead of from the src release archive. I forsee some users running this on modern lbmk with older release images. If the mrc-based target isn't there, the user may use an NRI-based target name, and think it works; they will insert without MRC. I foresaw this ages ago, which is why Caleb and I ensured that the script checks hashes, and hashes are included in releases. Therefore: for the time being, keep the MRC-based configs in lbmk but do not include images for them in releases. This can be done indefinitely, but I'll probably remove those configs entirely at some point. On the following boards, Libreboot now will *only* provide NRI-based ROM images for the following machines: * Dell OptiPlex 9020 SFF * Dell OptiPlex 9020 MT * Lenovo ThinkPad T440p * Lenovo ThinkPad W541/W540 I now recommend exclusive use of NRI-based images, on Haswell hardware. It's stable enough in my testing, and now supports S3. Signed-off-by: Leah Rowe <leah@libreboot.org>

safer, simpler error handling in lbmk in shell scripts, a function named the same as a program included in the $PATH will override that program. for example, you could make a function called ls() and this would override the standand "ls". in lbmk, a part of it was first trying to run the "fail" command, deferring to "err", because some scripts call fail() which does some minor cleanup before calling err. in most cases, fail() is not defined, and it's possible that the user could have a program called "fail" in their $PATH, the behaviour of which we could not determine, and it could have disastrous effects. lbmk error handling has been re-engineered in such a way that the err function is defined in a variable, which defaults to err_ which calls err_, so defined under include/err.sh. in functions that require cleanup prior to error handling, a fail() function is still defined, and err is overridden, thus: err="fail" this change has made xx_() obsolete, so now only x_ is used. the x_ function is a wrapper that can be used to run a command and exit with non-zero status (from lbmk) if the command fails. the xx_ command did the same thing, but called fail() which would have called err(); now everything is $err example: rm -f "$filename" || err "could not delete file" this would now be: rm -f "$filename" || $err "could not delete file" overriding of err= must be done *after* including err.sh. for example: err="fail" . "include/err.sh" ^ this is wrong. instead, one must do: . "include/err.sh" err="fail" this is because err is set as a global variable under err.sh the new error handling is much cleaner, and safer. it also reduces the chance of mistakes such as: calling err when you meant to call fail. this is because the standard way is now to call $err, so you set err="fail" at the top of the script and all is well.
