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/

The build system distinction between "bootprog" and "service" is
meaningless as boot programs are standard services.
As minix.service.mk simply imports minix.bootprog.mk, reduce confusion
by removing minix.bootprog.mk and placing the rules in minix.service.mk.

Periods are allowed in Make variable names, which let us simplify
a bit the Makefile.

This patch introduces a framebuffer to Minix. It's written for the ARM
port of Minix, but has an architectural split that separates the
hardware dependent part from the non-hardware dependent part. Futhermore,
this driver was developed using a screen that has a native resolution of
1024x600 pixels and having lack of support for obtaining EDID from the
screen. Consequently, it uses a hardcoded resolution of 1024x600.
The driver uses an interface based on the Linux ioctl API, but supports
only a very limited subset.
All cards in this family (RTL8101E, RTL8102E, RTL8103E, RTL8105E,
possibly others) should be recognized based on the added PCI ID.
The hardware version number of the RTL8105E has been added only to
serve as an example of a card that does not require modification of
certain undocumented registers.
- if supported, override BSY/DRQ flags and start the port anyway if it
times out with DET=3h status during device detection;
- no longer rely on the device signature to be set; unless a valid
signature is obtained, try both ATA and ATAPI device identification.
- do not start a port before the BSY and DRQ flags have been cleared;
as such, poll on device status rather than signature availability.
- change "ahci_sig_timeout" to "ahci_device_timeout" variable setting
accordingly; this variable determines the polling duration before a
newly attached device is given up on, and uses 30 seconds as default;
- use port connect changes (PCS/X/DET->1h) to kick off polling for an
attached device; detachment is still detected by means of PhyRdy
status changes (PRCS/N/DET<->3h).
- the "ahci_sig_timeout" variable now denotes the entire checking
period, and the delay between checks has been hardcoded; what was
previously "ahci_sig_checks" is now computed from those two;
- timeout values are no longer used for both millisecond and clock
tick values, and better typed;
- the computation of timeouts is no longer off by half a second.
There is no need to set/clear PxCMD.FRE on every port start/stop.
Also remove some already useless and now also incomplete port
reinitialization at startup.
* Generalize GPIO handling.
* Add libs to configure gpio's clocks and pads
* Add Interrupt handling.
* Introduce mmio.h and log.h
Change-Id: I928e4c807d15031de2eede4b3ecff62df795f8ac
* let busy loops timeout.
* Start using interrupt handlers.
* Allocate the ramdisk only when used.

Small GPIO driver that exports a few pins using a virtual file
system. Currently the two user leds and the user button are exported.

Due to the ABI we are using we have to use the earm architecture
moniker for the build system to behave correctly. This involves
then some headers to move around.
There is also a few related Makefile updates as well as minor
source code corrections.
* Updating common/lib
* Updating lib/csu
* Updating lib/libc
* Updating libexec/ld.elf_so
* Corrected test on __minix in featuretest to actually follow the
meaning of the comment.
* Cleaned up _REENTRANT-related defintions.
* Disabled -D_REENTRANT for libfetch
* Removing some unneeded __NBSD_LIBC defines and tests

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.

Also fix a potential issue where host tools would be compiled
dynamically under MINIX.
This also updates proto.common.dynamic to use the new placement
of the dynamic libraries (/usr/lib)
upgrade to NetBSD CVS release from 2012/10/17 12:00:00 UTC
Makefiles updates to imporve portability
Made sure to be consistent in the usage of braces/parenthesis at
least on a per file basis. For variables, it is recommended to
continue to use braces.
The tested targets are the followgin ones:
* tools
* distribution
* sets
* release
The remaining NetBSD targets have not been disabled nor tested
*at all*. Try them at your own risk, they may reboot the earth.
For all compliant Makefiles, objects and generated files are put in
MAKEOBJDIR, which means you can now keep objects between two branch
switching. Same for DESTDIR, please refer to build.sh options.
Regarding new or modifications of Makefiles a few things:
* Read share/mk/bsd.README
* If you add a subdirectory, add a Makefile in it, and have it called
by the parent through the SUBDIR variable.
* Do not add arbitrary inclusion which crosses to another branch of
the hierarchy; If you can't do without it, put a comment on why.
If possible, do not use inclusion at all.
* Use as much as possible the infrastructure, it is here to make
life easier, do not fight it.
Sets and package are now used to track files.
We have one set called "minix", composed of one package called "minix-sys"
.Split TTY in order to support both x86 and ARM.
.Add support for the TI 16750 UARTs on OMAP35x.
.Various other improvements:
.Kernel messages are printed using generic terminal write
functions. That is, they are no longer directly displayed
on the console.
.The console can now be displayed on any terminal. This
is configured by the "console={tty00,tty01,ttyc2,ttyc3,ttyc4}"
boot variable -- basically any valid /dev/tty* terminal.
.Cutify kernel messages with colors. Configured by
"kernelclr={1,2,3,4,5,6,7}" boot variable.
