The padconf library runs in user mode, but to actually affect the
padconf register contents, the processor has to be in privileged
mode. A full server based solution will be developed, but for now
just set the pinmux in the kernel at boot.

- use the proper make variable to ignore file lists
SLOPPY_FLIST instead of CHECKFLIST, which was a minix hack.
- Add BUILDOPTIONS such that the users can activate optional
features without editing the script.

-By adding MKGCC=yes and MKGCCCMDS=yes on the make commandline
it is now possible to compile and install GCC on the system.
Before doing this, if you are not using the build.sh script,
you will need to call the fetch scripts in order to retrieve
the sources of GCC and its dependencies.
-Reduce difference with NetBSD share/mk
Move Minix-specific parameters from bsd.gcc.mk to bsd.own.mk,
which is anyway patched, so that bsd.gcc.mk is now aligned
on the NetBSD version.
-Clean libraries dependencies, compiles stdc++ only if gcc is
also compiled (it is part of the gcc sources)
-Correct minix.h header sequence, cleanup spec headers.
-Fix cross-compilation from a 32bit host targeting MINIX/arm

- Enable installing binutils from the base system.
- Import texinfo which is required for the binutils tools
to be compiled.
- Also adapted the fetch rules to correctly generate the
gitignore files for gcc, and allow the case of multiple
modules in the same directory, as found in gnu/dist.

. with hz=1000, clock_t only lasts a few years.
whenever we can't express the desired realtime
in ticks because the distance with boottime is
too high, simply adjust bootime like we do for
otherwise negative values.

kernel:
. modules can be as big as the space (8MB) between them
instead of 4MB; memory is slightly bigger with DBG=-g
arm ucontext:
. r4 is clobbered by the restore function, as it's
used as a scratch register, causing problems for the
DBG=-g build
. r1-r3 are safe for scratch registers, as they are
caller-save, so use r3 instead; and don't bother
restoring r1-r3, but preserve r4
vfs:
. improve TLL pointer sanity check a bit

Increase driver process priority to prevent starvation. Without
special attribute drivers will have the same priority as other
userland processes this. Posix test 1 was taking so much resources
that it triggered alarms in the MMC driver.

When we send MMC commads that contain data the controller provides no
description of the order of events and we need to be able to send data
from and to the controller "when needed". Changed the code to react
on buffer read and buffer write ready based on interrupts.

Clock configuration will be needed by other/future subsystems such as i2c.
Extract the functionality from libgpio and put it into it's own library.

- setlogin() not available
- softfloat needed in -lminc for arm
- libminc: we have to set LIBCDIR for the included files,
so use that instead of LIBCSRCDIR

. always keep reading data from uart so the interrupt is
not continually asserted if data is sent but no process
reads it
. increase tx & rx fifo trigger levels -> reduces the number
of interrupts necessary
. bigger rx/tx buffers

. unpause() and revive() can race - revive() can run during
a device i/o unblock, causing two sendnb()s to occur, and the
2nd one to fail
. this can easily happen when a process is blocking on tty and
is then killed by a signal - tty cancels the i/o and then
kills the process by a signal

. the default entry for disabled ttys for getty
in /etc/ttys is "", but init crashed on handling that
string.

. ignore interrupt (stop interrupt check loop) if
interrupt bit not set; limit loop too
. mask off other bits when testing bits in the status register
. this fixes rs232 output that would otherwise never get re-triggered
as too many bits were set in the status byte to match the
possibilities.
