5acaa0814f kernel, ramdisk: some boot unification
To use the new SD building script, Linux has to be configured with
loop.max_part=15 on the command line (or set at module load time)
to make the loopback device see the partitions.

This commit removes a lot of differences between the ARM and x86
boot ramdisk and rc scripts. It changes the ARM build from running
from ramdisk to requiring a full filesystem on the SD image and
booting into it.

	. ramdisk: remove some arm-only utilities only used for running
	  from the shell
	. remove ARM-only rc.arm, proto.arm.small, ttys and mylogin.sh
	  boot-time ramdisk files
	. change kernel to add "arch" variable so userland knows what
	  we're running on from sysenv
	. make ARM use the regular ramdisk rc file, changed to distinguish
	  i386-only and ARM-only drivers; requires rootdevname to be set
	. change /etc/rc and /usr/etc/rc to start i386-only drivers only on
	  i386 systems
	. change the kernel/arm to have a special case for the memory
	  driver to load it higher so it can be bigger
	. add uEnv.txt, cmdline.txt and a for now highly linux-dependent
	  SD preparation script arm_sdimage.sh to the git repository in
	  releasetools/

aacce8f40c ramdisk:replace proto.sh by the c processor.
Replace proto.sh by the c processor to generate proto.gen in order
for us to have a more flexible way of selecting the files we want
in the ramdisk.

acac1f2fda Cross-compilation fixes
. Some Makefile fixes to automatically differentiate between a normal
  compilation and cross-compilation. Also, build compressed images.
. Harmonize ramdisk rc scripts for normal use case and ext2 ramdisk.
. ext2_ramdisk filesystem prototype fixes.

53f94f8ed4 dynamic executables on ramdisk support
See UPDATING about upgrading clang for dynamic linking.

	. allow executables on ramdisk to be dynamically linked; this means
	  putting a few required shared libraries and ld.elf_so on the ramdisk.
	. this makes the ramdisk (usage) smaller when they are dynamic, but
	  bigger when they're not.
	. also we can safely ditch newroot and call mount directly as that is
	  all newroot does.
	. create proto.common to share a bunch of entries between
	  small/nonsmall cases

59ff5cbd87 mfs: clean flag
. also implement now-possible fsck -p option
    	. allows unconditional fsck -p invocation at startup,
    	  only checking each filesystem if not marked clean
    	. mounting unclean is allowed but is forced readonly
    	. updating the superblock while mounted is now not
    	  allowed by mfs - must be done (e.g. by fsck.mfs)
    	  on an unmounted fs
	. clean flag is unset by mfs on mounting, and set by
	  mfs on clean unmounting (if clean flag was set at
	  mount time)

ebdac755af ramdisk: install all password-related files 2011-11-22 19:58:45 +01:00

cc17b27a2b Build NetBSD libc library in world in ELF mode.
3 sets of libraries are built now:
  . ack: all libraries that ack can compile (/usr/lib/i386/)
  . clang+elf: all libraries with minix headers (/usr/lib/)
  . clang+elf: all libraries with netbsd headers (/usr/netbsd/)

Once everything can be compiled with netbsd libraries and headers, the
/usr/netbsd hierarchy will be obsolete and its libraries compiled with
netbsd headers will be installed in /usr/lib, and its headers
in /usr/include. (i.e. minix libc and current minix headers set
will be gone.)

To use the NetBSD libc system (libraries + headers) before
it is the default libc, see:
   http://wiki.minix3.org/en/DevelopersGuide/UsingNetBSDCode
This wiki page also documents the maintenance of the patch
files of minix-specific changes to imported NetBSD code.

Changes in this commit:
  . libsys: Add NBSD compilation and create a safe NBSD-based libc.
  . Port rest of libraries (except libddekit) to new header system.
  . Enable compilation of libddekit with new headers.
  . Enable kernel compilation with new headers.
  . Enable drivers compilation with new headers.
  . Port legacy commands to new headers and libc.
  . Port servers to new headers.
  . Add <sys/sigcontext.h> in compat library.
  . Remove dependency file in tree.
  . Enable compilation of common/lib/libc/atomic in libsys
  . Do not generate RCSID strings in libc.
  . Temporarily disable zoneinfo as they are incompatible with NetBSD format
  . obj-nbsd for .gitignore
  . Procfs: use only integer arithmetic. (Antoine Leca)
  . Increase ramdisk size to create NBSD-based images.
  . Remove INCSYMLINKS handling hack.
  . Add nbsd_include/sys/exec_elf.h
  . Enable ELF compilation with NBSD libc.
  . Add 'make nbsdsrc' in tools to download reference NetBSD sources.
  . Automate minix-port.patch creation.
  . Avoid using fstavfs() as it is *extremely* slow and unneeded.
  . Set err() as PRIVATE to avoid name clash with libc.
  . [NBSD] servers/vm: remove compilation warnings.
  . u32 is not a long in NBSD headers.
  . UPDATING info on netbsd hierarchy
  . commands fixes for netbsd libc

7ae6f8740d ACPI driver loaded at boot time
- the acpi driver is part of the ramdisk and if present the rc script
  starts it before pci is started as pci needs if APIC mode is turned
  on.

b43f3b6bfc This patch copies the ext2 server onto the initial ramdisk, the final
patch to allow MINIX to boot from ext2.

To create a setup with MINIX on ext2, follow these steps:

- Assumptions:
  - there exists a primary partition c0dApB with a MINIX installation
    with GRUB support (/boot/image_latest exists on /dev/c0dApB)
  - there exists a free primary partition c0dCpD

- Create an ext2 filesystem on c0dApB (from Linux, until Tthom
  has ported mke2fs)

- Follow these steps (from a MINIX CD with ext2 support, another MINIX
  installation (not c0dApB) or Linux >= 2.6.35):

  mkdir /mnt/mfs /mnt/ext2
  mount /dev/c0dApBs0 /mnt/mfs
  mount /dev/c0dApBs1 /mnt/mfs/home
  mount /dev/c0dApBs2 /mnt/mfs/usr
  mount /dev/c0dCpD /mnt/ext2
  synctree  -f /mnt/mfs /mnt/ext2
  echo root=/dev/c0dCpD > /mnt/ext2/etc/fstab

  (note: no subpartitions used because that would confuse an unmodified
  bootloader)

- Add the new MINIX installation to GRUB according to steps 7&8 in
