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.

vendor.sh: don't use XBMK_CACHE for appdir

2024-07-18T23:48:09+00:00

the me_extract function prefixes it with PWD in
some cases, but we can't predict where appdir
will point to.

the "app" directory is not intended to be a cache
anyway, so it doesn't make sense to put it in
the cache directory.

it's essentially scratch memory.

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.

git.sh: fix typo in git command

2024-07-18T22:11:45+00:00

the || : condition should be used, whereas i just
wrote : by mistake. this was done in a previous change.

fix it now.

git.sh: fix lack of error exits on fault

2024-07-18T22:09:59+00:00

a previous change made it more redundant, falling back
on old behaviour (direct downloading, not cached), but
the way it's done means that the function never returns
an error condition in practise.

this patch fixes it.

build: remove tmp/ on release archives

2024-07-18T13:13:11+00:00

i overlooked this before. remove it. the directory
happened to be empty when i tested archives, but it's
still not a good thing that we have it. remove it!

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

allow using coreboot's build system to add payload

2024-07-17T18:06:53+00:00

lbmk must still define payloads, but specific configs
may use coreboot's build system instead.

you might use this to add your own config with, say,
tianocore payload, using coreboot.git to build it,
rather than using lbmk's choice of payloads.
