Basically, I really like OpenBSD coding style, and I want to
replicate this, somewhat, in shell scripts.

Top-down order is easier to read, for greater understanding.
What's moved is initialisation. The glue that calls Build_deps
and Download_needed still need to be at the bottom.
|
|
It's called first, so declare it first!
|
|
|
|
for example, files being downloaded have nothing to do
with the ME; they are merely compressed, and contain many
files in addition to it
|
|
When using e.g. -p grub in build/boot/roms, it will
error out. This patch fixes that.
E.g.
./build boot roms t440pmrc_12mb -p grub
Seldom used feature and it was overlooked. Most people
won't use the option that triggered the error.

these boards are almost impossible to find, and have always been
buggy, it doesn't look like there will be any viable testing or
development on it
it's currently broken in master, on coreboot. if someone wants to
fix and re-add to lbmk, they can do that
use older libreboot releases to flash this board, if you wish
(i *am* adding te the issue tracker, a note about this commit,
with a view to re-adding it one day)

rename board configs, and add to sources file the
t530/w530 boards
in some situations, the files weren't being downloaded

MRC caches in a certain way, that Heads was able to work
around in their build system, for this board.
I've adapted the relevant config differences, from their project
as of heads revision 96440b928acb06de5b925ea12014c9c280b23165
The downside is that CBFS now has to be 8MB in size. The upside
is that the machine also boots much faster
See:

I have not adapted their IFD changes, versus Libreboot, because theirs
simply has a different version string, and uses different read/write
permission bits for regions as defined in the IFD.
This affects:
t440p_12mb_mrc
w541_12mb_mrc
S3 suspend/resume still broken on these targets which use the libre
MRC init (replacement code by Angel Pons, recently merged in lbmk):
t440p_12mb
w541_12mb
With clever use of FMAP, the rest of the BIOS region might still be
used. However, for our purposes, 8MB CBFS will do just fine.
Heads's changes configure MRC so that caching is handled properly,
for when the machine returns from sleep. Setting CBFS to be any
higher will result in slower boot times, and broken S3 resume, due
to MRC cache misalignment (this is based on my understanding, reading
through the Heads project looking at their research on this).
At some point in the future, Angel's libre MRC code will probably
be finished, and merged, with more fine tuning possible to allow
bigger CBFS sizes.

libre mrc on haswell is quite buggy for now, but works in
a limited fashion
this patch re-adds the old configs, but as _mrc for example
t440p_12mb_mrc instead of t440p_12mb
and t440p_12mb (without _mrc) still uses the libre mrc code
|
|
i found that with libre mrc, usb was broken in grub
however, it worked nicely in seabios
for our purposes, doing seabios-only roms in text mode
is best for now
i'm going to re-add mrc.bin, but for t440p_12mb_mrc
and w541_12mb_mrc, as new config names. the regular
t440p_12mb and w541_12mb will continue to use libre
mrc, but the _mrc ones will use mrc.bin and retain the
grub payload in board.cfg

courtesy of Angel Pons from the coreboot project
this uses the following patch set from gerrit, as yet
unmerged (in coreboot master) on this date:
https://review.coreboot.org/c/coreboot/+/64198/5
logic for downloading mrc blobs has been deleted from
lbmk, as this is now completely obsolete (for haswell
boards)
if other platforms are added later that need mrc.bin,
then logic will be re-added again for that

this fixes the build error:
Error: name not set
Usage: ./download gitmodule [name]
when running:
./download all
running "all" runs all scripts under downloads,
one of which was the gitmodule script itself, therefore
being run without argument
|

they don't even boot in pcbox properly, and the real
hardware is not much to talk about
useless port

some checks check for specific utils, which are
then used to indicate the existence of other utils,
which means that building them singularly, as is
currently done, may result in errors later if another
tool doesn't exist compiled yet
this is an obscure bug, fixed by this patch. more of a
workaround really. a dirty hack. when checking for any
of the coreboot utilities required, build all coreboot
utilities that are possibly required
the utilities are small enough that this does not add
much extra time to build, and in most cases, all of them
will be needed anyway

352MB VRAM causes stability issues, according to some reports
users can still set it to the higher level when building, if

U-Boot can be configured via environment variables which can be saved to
various storage devices. This usually defaults to MMC or SPI depending
on where it boots from, but assumes the device's layout is controlled by
U-Boot.
We should store the environment in SPI flash, but we also need to
configure coreboot FMAPs to reserve the area U-Boot would use as its
environment storage. For now, disable environment storage by setting
ENV_IS_NOWHERE=y to avoid overwriting random regions of SPI or MMC if
someone tries to save the variables.

Set default U-Boot revision to v2023.01 and rebase patches on top of
that. Upstream kconfig status is a bit unstable, so updating configs
with `make oldconfig` would miss important upstream changes.
For each board, run `make savedefconfig` and `diffconfig -m` at the old
version to get a diff from upstream defconfigs. Fix those affected by
upstream changes, like SYS_TEXT_BASE being renamed to TEXT_BASE. Then
append those to the new version's defconfigs and run `make olddefconfig`
to get updated configs.

The USB 2.0 ports on Exynos boards need the relevant driver enabled by
USB_EHCI_EXYNOS. This is enabled by default depending on USB_EHCI_HCD.
It's already enabled on snow and spring, but apparently not on peach
boards, as discovered from other people's attempts to enable it [1][2].
Enable it also on the peach_pi and peach_pit.

The display driver on the veyron boards needs reset drivers, more
specifically RESET_ROCKCHIP. This is enabled by default depending on
DM_RESET, which an upstream commit enables for veyron_jerry claiming it
fixes the display [1]. Enable it also in our configs, but for other
veyrons as well.

By making lbmk fully POSIX-compliant, it will be easier to port lbmk to
other systems implementing POSIX such as Alpine Linux and FreeBSD.

due to upstream bloat, these no longer fit. it will have to be
fixed in the next libreboot release
