quackboot (same idea as klompboot), from audit6

2024-07-20T02:27:06+00:00

this is based directly on the audit6 final revision.

same idea as klompboot. remove u-boot and arm support,
remove pico-serprog, remove support for making release
archives, and basically see how small the build
system can possible get.

quackboot *beats* the very first klompboot, at 790 lines,
because klompboot 1 was just over 800 lines. klompboot 2
was 701 lines. vendor file logic is about 200 sloc so
the next klompboot will be about 600 lines.

this is the very first quackboot.

put cachedir in environmental variable

2024-07-18T23:37:11+00:00

XBMK_CACHE is now used, instead of hardcoding cache/

this is exported initialised to cache/, if unset.
this means you can set your own directory, and it means
./update release will use the same directory.

this means bandwidth wastage is further avoided.

trees: hardcode makeargs for xgcc

2024-07-17T22:25:44+00:00

if coreboot itself is being handled, crossgcc has the
correct makeargs, setting the number of build threads.

however, other projects can specify "xtree" pointing to
a given coreboot tree, and build crossgcc for it.

one workaround may be to use trees -d coreboot TREE,
but then extra code would have to be written to make
it avoid other things like building cbfstool, which is
not required for just building crossgcc.

the cleanest way to do it is to simply hardcode it. the
value is set exactly the same as regular coreboot makeargs.

this fixes a bug, where some builds of crossgcc are made
on a single thread, rather than using XBMK_THREADS. this
patch forces it to always use CPUS=$XBMK_THREADS

trees: remove unnecessary command

2024-07-17T17:55:18+00:00

we no longer need to remove cache/ per project, because
it's removed in bulk at the end, in the main build script,
when generating release archives.

repo/ becomes cache/repo/

trees: auto-delete+auto-rebuild if project changes

2024-07-17T15:34:34+00:00

actual source code is not scanned, but config directories are
scanned. simply get the checksum of each file under config/
pertaining to a given project/tree, and also for the given
target. coreboot utilities are also handled.

if it changes, in any way, delete and re-build automatically.

such deletions should probably still be done manually, as part
of understanding the build system, but this change should make
the build system much easier to use during development.

trees: also remove single-tree repo/p/

2024-07-17T12:27:50+00:00

single-tree repos were not previously cached, but now
they are and they have to be handled.

this, as also alluded to in the previous commit, is done
when preparing release archives (XBMK_RELEASE=y)

trees: remove repo/p, not src/p/p

2024-07-17T12:24:21+00:00

repo/p/ does not have its revision reset, so it
changes unpredictably, and it's not used in builds.

this used to be src/p/p/ - the context here is multi-tree
projects, in source archives.

remove util/autoport

2024-07-16T02:57:08+00:00

upstream has merged all of the changes that it contained,
so we don't need this anymore. we'll have the newer upstream
changes on the next general revision updates for coreboot,
within config/coreboot/

trees: move dependency building to new function

2024-07-13T22:07:45+00:00

configure_project is a bit big. move the dependencies
build logic to a new function.

it may be desirable in future to make the way that
function works the way all build commands are done.

for example:

./update trees -b coreboot x230_12mb

would become:

./update trees -b coreboot/x230_12mb

this would enable to mix and match multi/single tree
projects. for now, leave things as they are.
