2023-06-19build/boot/roms: Support removing microcodeLeah Rowe
From now on, the following rules are available for all mainboards, in resources/coreboot/boardname/board.cfg: * blobs_required="n" or "y" * microcode_required="n" or "y" The blobs setting, if set to "n", simply renames filename.rom to filename_noblobs.rom. The microcode setting, if set to "n", copies the ROM (with or without _noblobs) to filename_nomicrocode.rom (if blobs="n", it would be filename_noblobs_nomicrocode.rom). Where "nomicrocode" is set, ROMs with microcode will still be provided by lbmk and in relesase, but ROMs will also be provided alongside it that lacks any microcode updates. If the *original* ROM already lacks microcode updates, then the original ROM will be *renamed* to include "nomicrocode" in the name. This is done on images for ARM platforms, for instance, where microcode is never used whatsoever. Example filenames now generated: seabios_e6400_4mb_libgfxinit_corebootfb_noblobs_nomicrocode.rom seabios_e6400_4mb_libgfxinit_corebootfb_noblobs.rom seabios_withgrub_hp8300usdt_16mb_libgfxinit_corebootfb_colemak_nomicrocode.rom seabios_withgrub_hp8300usdt_16mb_libgfxinit_corebootfb_colemak.rom uboot_payload_gru_kevin_libgfxinit_corebootfb_noblobs_nomicrocode.rom A vocal minority of people were not happy with some of the changes made in Libreboot last year, including on existing supported hardware from before those changes were made. I did this before the last release, out of respect: https://libreboot.org/news/gm45microcode.html (re-add mitigations for no-microcode setup on GM45) This new change is done as an further, extended courtesy. Tested and works fine. (testing using cbfstool-print) Actual Libreboot policy about binary blobs is nuanced. See: https://libreboot.org/news/policy.html (reduction policy) and: https://libreboot.org/freedom-status.html (implementation) Well, the status page talks about descriptor vs non-descriptor on Intel platforms, and where me_cleaner is used (on platforms that need Intel ME firmware), it regards the descriptored setups to be blob-free if coreboot does not require binary blobs. In this paradigm, microcode updates are not considered to be binary blobs, because they aren't technically software, they're more like config files that just turn certain features on or off within the CPU. However, for lbmk purposes, "noblobs" means that, after the ROM is fully ready to flash on the chip, there will be no blobs in it (except microcode). So for example, an X200 that does not require ME firmware is considered blob-free under this paradigm, even though Libreboot policy regards X230 as equally libre when me_cleaner is used; in this setup, ROMs will not contain "blobfree" in the filename, for X230 (as one example).

Still on Gerrit. ME downloader failed with HP update file, so let's just use Lenovo's instead. Both contain identical ME8_5M_Production.bin files. Tested and working: * Native raminit with both DIMMs * Libgfxinit textmode and framebuffer on both DisplayPorts and VGA * External USB2 and USB3 ports: they all work * USB 3.0 SuperSpeed (rear, 4 ports) * Ethernet * Mini-PCIe WLAN * SATA: 2.5" SSD and optical drive bay * SeaBIOS and GRUB (boot to linux) * PS/2 keyboard and mouse * S3 suspend and resume, wake using USB keyboard * Headphone output, line out, internal speaker * Wake on LAN * Rebooting * CMOS options & nvramcui Untested: * Line in, mic input * MXM graphics card * EHCI debug Not working: * Mini-PCIe USB: I couldn't get it working on vendor BIOS either, so maybe it just isn't present * PS/2 keyboard wake from S3 * mSATA (I have no mSATA drives)

2023-06-13util/spkmodem-recv: remove unnecessary error checkLeah Rowe
the loop in main() already checks EOF, and errno is properly handled at the end of main() we only need to call ferror(), to check error state this fixes a bogus error message when pressing ctrl+D to terminate the program, *which is the intended way to terminate this program* (that, or EOF is reached in any other another way) do not treat intended behaviour as an error condition!

2023-06-13Revert "Remove most of Ferass's lbmk contributions"Leah Rowe
This reverts commit a4ea2867319471d9fe7d4ee540881e0286b4d3cf. The licensing audit has been abandoned. I will not be re-licensing in bulk to MIT. I can still use MIT license on new works, e.g. utilities, but there's really no pressing need to re-license lbmk. It's just shell scripts, and most of what it interacts with (coreboot, grub, seabios) is GPL anyway. So who cares? Ferass's patch was removed due to refusal to re-license, but the decision to re-license has been canceled. I'm now aiming for a quick stable release.

2023-06-12lbmk: Fix regressionsNicholas Chin
- A spurious semicolon caused the arguments to printf in die() to be executed instead of printed - ${@} in die() needs to be in quotes or else printf prints each word on a separate line - The number of arguments to main() does not include main itself so it should be comparing against 1 instead of 2 to determine if enough arguments were supplied.
2023-06-12util/spkmodem-recv: re-add full license headerLeah Rowe
i forked spkmodem-recv from coreboot, who forked it from gnu grub. gnu grub's version has the full header, with copyright declared as belonging to the fsf coreboot made changes after forking it, and later replaced the license declaration with an equivalent SPDX header, but they also removed the FSF's copyright declaration, which by itself does not void the declaration anyway, i just feel better re-adding the full declaration. make it so!

2023-06-04util/spkmodem-recv: warn on unhandled exit errorLeah Rowe
my style of C programming is this: always return errno upon exit from the program, or from a thread. handle errno in the calling/forking function. returning errno at the end of main has this intention: if an unhandled error occured, the program exits with non-zero status. a correctly written program should *never* return non-zero at the end of main, and if it does, this indicates a bug in the code (per my code style / philosophy). so, warn the user with a message if this occurs. the intention is that this message should never be printed. do not use assert() for this. i don't believe in that. such a test should always be present, for everyone.

when calling fread(), errno may be set to EOVEFLOW if the range being read will cause an integer overflow if end-of-file is reached, errno may not be set. when calling this function, you must check errno or check feof() - ferror() should also be checked, so this check is added immediately afterwards in the code ferror() does not set errno, so ERR() is used to set errno to ECANCELED as program exit status further separate reading of frames into a new function Signed-off-by: Leah Rowe <leah@libreboot.org>
