This extends make_fiwix_initrd and kexec-fiwix to support command
line parameters, instead of hardcoding relevant values within the
C sources. This way, it becomes possible to alter e.g. ramdisk size
without affecting checksums.
While we're at it, also support loading a memory map from file.
And while we're at it, use a more sustainable way of getting the
address of the next file to be written to.
Since builder-hex0 doesn't distinguish directories from zero-length
files, this has a limitation that it won't copy any zero-length
files or empty directories. Only one such file is important for the
bootstrap process (mes/config.h), which is recreated using an
improve step.
* Enable additional hardware drivers in Linux for better bare metal
display, network & input device compatibility
* Disable ATA-over-Ethernet support, because it spams the network
with unnecessary packets, is basically useless for bootstrapping,
and may even be a security risk
* Increase Fiwix initrd size to 1280MB to fit a larger Linux build
* Make the Fiwix kexec size configurable the same way as initrd
(and reduce from 280MB to 256MB which is sufficient in my testing)
* Use a more conservative memory map for Fiwix & Linux
* Boot Linux with consoleblank=0 on bare metal, so the build won't
go blind after 5 minutes
* Support kexec-fiwix with interrupts disabled (will be useful later
when builder-hex0 is updated)
- This idea originates from very early in the project and was, at the
time, a very easy way to categorise things.
- Now, it doesn't really make much sense - it is fairly arbitary, often
occuring when there is a change in kernel, but not from builder-hex0
to fiwix, and sysb is in reality completely unnecessary.
- In short, the sys* stuff is a bit of a mess that makes the project
more difficult to understand.
- This puts everything down into one folder and has a manifest file that
is used to generate the build scripts on the fly rather than using
coded scripts.
- This is created in the "seed" stage.
stage0-posix -- (calls) --> seed -- (generates) --> main steps
Alongside this change there are a variety of other smaller fixups to the
general structure of the live-bootstrap rootfs.
- Creating a rootfs has become much simpler and is defined as code in
go.sh. The new structure, for an about-to-be booted system, is
/
-- /steps (direct copy of steps/)
-- /distfiles (direct copy of distfiles/)
-- all files from seed/*
-- all files from seed/stage0-posix/*
- There is no longer such a thing as /usr/include/musl, this didn't
really make any sense, as musl is the final libc used. Rather, to
separate musl and mes, we have /usr/include/mes, which is much easier
to work with.
- This also makes mes easier to blow away later.
- A few things that weren't properly in packages have been changed;
checksum-transcriber, simple-patch, kexec-fiwix have all been given
fully qualified package names.
- Highly breaking change, scripts now exist in their package directory
but NOT WITH THE packagename.sh. Rather, they use pass1.sh, pass2.sh,
etc. This avoids manual definition of passes.
- Ditto with patches; default directory is patches, but then any patch
series specific to a pass are named patches-passX.
