Riku introduced three new patches:
* Add support for multiple chip selects. This allows you to
control multiple chips from the same clip, on systems with
dual flash setups, at least theoretically.
* Enable pull-up on unused chip selects - pull them high so
that chips you connect that to are deactivated while flashing
the target chip. This could be used on thinkpad W541 for
instance, where miso/mosi have 0ohm between them via the two
flash ICs. You could pull the other chip select high.
* Documentation for the above, in the pico-serprog readme.
This goes in tandem with a patch from Riku, present in the
recently integrated flashprog project, namely:
commit ddb6d926783d4f9cbee04c7392718ed8f89daa0e

serprog: Add support for multiple SPI chip selects
This functionality will therefore be present in the next
release of Libreboot.

Nico Huber is the rightful project lead. I do not support
the coup that occured within the flashrom project. Nico
has always been of great service to the Libreboot project,
by virtue of his work on both coreboot and flashrom.
Nico Huber was unfairly removed from the flashrom project
infrastructure, due to unfounded accusations hurled at him
by flashrom's new project lead. The accusations are unfounded
because no evidence was given.
Use Nico Huber's fork, named flashprog. We will work with
flashprog from now on.

in some cases, the build system was needlessly, and sometimes
erroneously, creating crossgcc symlinks, which then caused an
issue, namely:
in lbmk release builds, dell e6400 is build before fam15h boards,
and it sets xtree, but fam15h_rdimm doesn't, and later this would
cause fam15h_rdimm boards to use xtree="default" (because they don't
set xtree), causing the newer toolchain to be used on coreboot 4.11.
this patch fixes the issue. quite a simple problem, actually.

these should be using the rdimm tree for crossgcc,
so define it explicitly. the build system creates
a symlink too, but it's still best that we use it.

a tree can specify:

this will make the other tree be downloaded. this is
used for coreboot trees, to ensure that dependency
trees are downloaded, because trees can now re-use
crossgcc from other trees.

There is no need to add multiple keymap files, because
GRUB can load keymaps from CBFS. The current build logic
is designed to avoid building multiple GRUB binaries,
which are expensive computationally because each one
would then have to be compressed for each board.
This patch provides the best of both worlds: less space
used in flash like in the old lbmk design (1 keymap per
board), but retaining the current build speeds and therefore
not re-introducing the slowness of lbmk's previous GRUB
build logic.
The grub.cfg file has been modified, accordingly. It now
only loads a keymap.gkb file from CBFS, by default. It does
this, only if that file exists; if not, GRUB already defaults
to US Qwerty layout anyway.
ALSO: compress all keymap gkb files with xz -6
GRUB automatically decompresses files when accessed.
This results in about 2KB of flash space saved in CBFS.
Here is real-world data, showing the increased flash space:
< fallback/payload 0x3eb80 simple elf 548821 none
< keymap.cfg 0xc4bc0 raw 16 none
< (empty) 0xc4c00 null 11633316 none
---
> fallback/payload 0x3eb80 simple elf 546787 none
> keymap.gkb 0xc43c0 raw 344 none
> (empty) 0xc4540 null 11635044 none
This was taken by diffing the cbfstool "print" output,
both before and after. The *after* result is with this change.
11633316. In this example, 1728 bytes have been saved. Therefore,
with compression taken into account, this patch saves about 1.7KB
of space in CBFS.
This change means that lbmk can now scale to support hundreds
of keymaps, without increasing the amount of flash space used,
in each given image. Since the keymap files are compressed in
lbmk.git, in advance, we spend no additional time on compression
at build time. The resulting change in build speed in negligible.
Adding your own keymap.gkb file was already possible, for changing
the keymap in libreboot images, if you didn't want to change the
memdisk (and thus re-compile grub.elf). Now, this is the default
behaviour, and the only way to do it. It's much more efficient.
The original keymap files can be restored, by running unxz.

the "kmapdir" variable was removed in an earlier audit,
but was overlooked for -k because that option was untested.
rather than initialise the variable, re-use grubcfgsdir.
this fix enables e.g. "-k usdvorak" to work again.

In order for the EC to maintain the state of whether or not to set the
flash descriptor override across a power cycle, the AC adapter must be
connected, as the system leaves the voltage rail that the EC uses
powered under this condition. Without this, the utility may fail,
continually asking the user to power off and on.
On Linux, CONFIG_X86_IOPL_IOPERM must be set for the kernel, or else the
iopl call will error with "Function not implemented". Make a note of
this in case a user runs into this issue.

cbmk 9429287 is the present canoeboot revision, on this day,
two commits after canoeboot 20231107
the cbmk revision was based on lbmk c4d90087, but lbmk
has developed a lot since, right up to f5b04fa5. lbmk
c4d90087 was four commits after libreboot 20231106
this patch brings cbmk up to date, versus lbmk f5b04fa5,
which is 135 commits after libreboot 20231106 (not 4)
therefore, the next canoeboot release shall import lbmk
changes made *after* lbmk revision f5b04fa5. good day!
In English (the above is for my reference, next time
I make a new canoeboot release):
This imports all of the numerous improvements from
Libreboot, sans the non-FSDG-compliant changes. You
can find a full list of such changes in the audit4 page:
https://libreboot.org/news/audit4.html
A full canoeboot-ised changelog will be available in
the next canoeboot release, with these and subsequent
changes. Most notable here is the update to the new
GRUB 2.12 release (instead of 2.12-rc1), and the
improvements Riku made to pico-serprog. And the build
system improvements from lbmk, such as improved, more
generic cmake and autoconf handling.
Canoeboot-specific changes: I also tweaked the deblob
logic, to make it less error-prone. The new design
changes imported into cbmk (based on latest lbmk) somewhat
broke the deblob logic; it was constantly reminding the
user that blobs.list was missing for coreboot,
at config/coreboot/blobs.list - coreboot is a multi-tree
project in both cbmk and lbmk, and the deblob logic was
tuned for single/multi, but was treating coreboot as both.
for simplicity, i removed the check for whether blobs.list
is present. this means that the operator must ensure that
these files are present, in any given revision, where they
are required on a given set of projects (and the files are
all present, in this update to cbmk)
Also of note: the grub.cfg improvements are included in this
cbmk update. The improved grub.cfg can find grub/syslinux
configs by default, not just grub anymore, also finds extlinux,
and will also find them on EFI System Partition - in addition,
UEFI-based install media is also more robust; although cbmk
doesn't provide UEFI configurations on x86, our GRUB palyoad
does still need to work with distro install media, and many
of them now use UEFI-based GRUB configurations in their
installation media, which just happen to work with our GRUB

we skip downloading blob repositories, and we delete errant
blobs in lbmk. the CONFIG_USE_BLOBS option, if enabled, can
make the coreboot build system download certain binary blobs,
which we are to avoid in the canoeboot project.
in practise, canoeboot releases are already deblobbed. this change
just makes it less likely that there will be rgressions in future.

changes after libreboot 20231101 were imported,
up to libreboot 20231106, and then to revision:
c4d90087535617d4fb31ca94803f9426010cfec5
i945 and gm45 configs were re-done, and dell e6400
was moved to its own tree with the ddr2 fix moved
there, to prevent breakage on ddr3-based gm45 boards
(look at libreboot 20231106 for more info)
several fixes are present in this canoeboot release,
that were only merged in libreboot *after* the
libreboot 20231106 release, and they are:
* c4d90087 add grub mods: diskfilter,hashsum,loadenv,setjmp
* d0d6decb re-add grub modules: f2fs, json, read, scsi, sleep
* 86608721 nvmutil: print usage
* f12f5c3a nvmutil: fix makefile
the release documentation has also been updated,
pulling down newer cbwww and cbwww-img based on
the new canoeboot 20231107 release announcement
