2023-05-16util/spkmodem_recv: Return errno in mainLeah Rowe
This is a good general practise, to catch errors. Any errors found can then be handled in code. Signed-off-by: Leah Rowe <leah@libreboot.org>

There was literally no error handling before. Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-05-16util/spkmodem_recv: Move logic out of mainLeah Rowe
Main should only be a skeletal structure. Actual logic should always be handled externally. Signed-off-by: Leah Rowe <leah@libreboot.org>

2023-05-16util/spkmodem_recv: Import from corebootLeah Rowe
Imported from util/spkmodem_recv at coreboot revision: e70bc423f9a2e1d13827f2703efe1f9c72549f20 This is a client for spkmodem, to allow serial console via PC speaker. I've decided to import it in lbmk, because I heavily modified it. The patches will be applied next. Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-04-30util/e6400-flash-unlock: do void on ec_fdo_commandLeah Rowe
the return value was never used
2023-04-24don't force console mode in grubLeah Rowe
the deleted patch (in this commit) was written to fix an issue theoretically; it hasn't been fully tested, and some people have reported strange issues since this patch was merged - there is no proof that this patch causes them, but removing this patch is the correct thing to do regardless
2023-04-19util/e6400-flash-unlock: restore READMENicholas Chin
when nicholas added this, he removed the README because it's going on libreboot.org instead. however, i merged a WIP version of his page for now because i want to get the e6400 going in libreboot sooner. so, temp-readding this README. will just link to this on codeberg or something, from the lb docs NOTE: I didn't write this README, hence author field set in the commit. Nicholas wrote it, but I (Leah Rowe) am just adding it. so, git author set to nicholas, not me
2023-04-19Add E6400 flash unlock utilityNicholas Chin
Adding it to lbmk for now as it is not yet in coreboot. If it is merged into coreboot we can just reference the one there. The original README will be incorporated into a new page on lbwww, so README.md just points to a placeholder URL that should match the new page.
2023-04-15util/nvmutil: sort includes alphabeticallyLeah Rowe
small nitpick, but i try to use openbsd style since i like that style. upon further reading of their style guidelines today, it was revealed to me that for includes, they: * sort sys/ includes alphabetically, at the top * after sys/ includes, have an empty line * includes for networking-related headers below that * empty space below networking headers if there * after that, have the rest of the includes, sorted alphabetically at least, that is my understanding. i have to admit, it does look cleaner not really that critical but why not do it?
2023-04-11util/nvmutil: don't display errant whitespaceLeah Rowe
At the end of each line is an errant space. Fix that.
2023-04-08add ich9utils back to utilsLeah Rowe
don't download it. keep it in lbmk. libreboot moved to codeberg for git hosting, and i didn't want to keep lugging around an extra git repo just for one tiny project.
2023-04-07util/nvmutil: even crazier code size reductionLeah Rowe
2023-04-07util/nvmutil: yet more code size optimisationLeah Rowe
2023-04-07util/nvmutil: more code size optimisationsLeah Rowe
2023-04-07util/nvmutil: minor code size optimisationLeah Rowe
not just sloccount, but compiled binary size as tested with tcc on an x86_64 host
2023-04-07util/nvmutil: fix possible regressionLeah Rowe
i went too hard on the sloc reductions a check inside a for loop could cause incomplete reading of gbe images revert that
2023-04-06util/nvmutil: minor code cleanupLeah Rowe
also removed some unnecessary checks fixed the check of pwrite's return value (it should check for -1)
2023-04-06util/nvmutil: remove unnecessary else statementLeah Rowe
2023-04-06util/nvmutil: less annoying commentsLeah Rowe
added a few that were more useful deleted a few obnoxious ones
2023-04-06util/nvmutil: remove duplicated logicLeah Rowe
the byteswap() function is used for big endian host compatibility, but it can also be used to swap words in the stored mac address
2023-04-06util/nvmutil: one more commentLeah Rowe
2023-04-06util/nvmutil: add useful code commentsLeah Rowe
2023-04-06util/nvmutil: remove unnecessary debug messagesLeah Rowe
these were put in when i was testing the feature to limit read/written bytes in loading/saving of files
2023-04-06util/nvmutil: serious re-factoring, part 2Leah Rowe
the code is smaller
2023-04-06util/nvmutil: consolidated error messageLeah Rowe
2023-04-06util/nvmutil: serious re-factoring (speed boost!)Leah Rowe
word/setWord no longer mitigates endianness. instead, all bytes are swapped after reading and before writing the file, and only if the host is big endian this improves performance on little endian hosts, which is most machines, and the code is much simpler, so it's more robust and less likely to break mac address endianness made more clear in code, including with a comment that explains it (the nvm section contains little endian words, *except* the mac address whose words are stored big endian)
2023-04-05util/nvmutil: fix faulty zeroes-mac-address checkLeah Rowe
it was resetting the total for each nibble. absolute epic fail on my part. fixed now.
2023-04-05util/nvmutil: minor code cleanupLeah Rowe
2023-04-05util/nvmutil: move mac address parsing to functionLeah Rowe
2023-03-06util/nvmutil: optimise rhex() furtherLeah Rowe
reduce the number of calls to read() by using bit shifts. when rnum is zero, read again. in most cases, a nibble will not be zero, so this will usually result in about 13-15 of of 16 nibbles being used. this is in comparison to 8 nibbles being used before, which means that the number of calls to read() are roughly halved. at the same time, the extra amount of logic is minimal (and probably less) when compiled, outside of calls to read(), because shifting is better optimised (on 64-bit machines, the uint64_t will be shifted with just a single instruction, if the compiler is decent), whereas the alternative would be to always precisely use exactly 16 nibbles by counting up to 16, which would involve the use of an and mask and still need a shift, plus... you get the point. this is probably the most efficient code ever written, for generating random numbers between the value of 0 and 15
