9b1cba84ac Move the GPIO bank initialization to a new function to make easier to detect
errors.

Reset the GPIO module during the initialization.  This is guaranteed to be
the same as a hardware reset.  Tested on AM335x (BBB) and checked against
the omap3 and omap4 TRM.

Do a better job freeing resources when there are errors and on
ti_gpio_detach().

cf44c89bba Some xdev fixes:
- if TARGET_ARCH is not defined and XDEV_ARCH is defined then early define
  TARGET_ARCH to the valud of XDEV_ARCH: This allow the xdev-build target
  to be able to correctly chose the compiler it needs to build
- Allow overwriting XDTP to allow a user to not chose where the xdev env will
  live in
- Fix build for gcc only xdev (like ia64) by providing the proper -B to the
  toolchain and not relying on gcc being installed already in base
- Fix TOOLS_PREFIX so the generated toolchain has the right default sysroot when
  installed intead of getting the DESTDIR one
- Fix supporting DESTDIR
- Also overwrite CXX (needed for cross building c++ libraries with clang) and
  CPP (needed to cross build some libraries when gcc is the target default
  compiler but gcc is not installed on the building host)

3651faa511 Make -f set -a, as required by the standard.
From the original OpenBSD commit message:

  restore the traditional behavior of -f implying -a; apparently Keith
  Bostic forgot to restore it when the -f flag was put back on 2nd of
  September 1989, after being removed on 16th of August as a
  consequence of issues getting it working over NFS, so deviation from
  traditional UNIX behavior in all BSDs looks like an historical
  accident; as a side effect, this change accommodates behavior of
  this option to IEEE Std 1003.1-2008 (``POSIX.1'').

  joint work with jmc@ (who found the inaccuracy in our
  implementation), schwarze@ (who provided a detailed tracking of
  historical facts) and millert@

c3f5e9c515 Implement GNU's extension of 'status' operand. The GNU syntax is
borrowed where syntax status=noxfer means no transfer statistics
and status=none means no status information at all.

This feature is useful because the statistics information can
sometimes be annoying, and redirecting stderr to /dev/null would
mean error messages also gets silenced.

0140748043 Rework the cpu frequency management code for imx6.
This adds the concept of "operating points," combinations of frequency
and voltage at which the cpu is known to work correctly.  Some day these
should come from FDT data, but for now the table is hard-coded.

This also allows tuning the min and max operating frequencies.  The min
frequency is what the thermal management code will slow down to if the
core temperature gets too high.  The max frequency is what gets used if
the temperature is okay.

Normally the max cannot be set higher than the value burned into the
ocotp fuses as the chip's rated max, but there is now a new sysctl+tunable
cpu_overclock_enable; when set to non-zero it allows raising the frequency
above the ocotp value: USE WITH CARE!  (At least one of my imx6 boards
has a cpu whose ocotp values never got set correctly; they claim a max
of 792mhz, but the physical markings on the chip say it's good to 1ghz.)

Because all these values affect the entire SoC, there is a new sysctl
node, hw.imx6, where all these values live.  The values that are currently
under dev.imx6_anatop.0 should probably move to hw.imx6 too, because
"anatop" doesn't even mean anything to me, let alone to an end user.

2a4eeaa4d2 Change NO_EVENTTIMERS from an arm-specific to an MI option, so that it can
be used in MI code.

This is intended as a temporary measure to unbreak the build.  The real fix
is to write event timer drivers for legacy arm hardware, then get rid of
this option completely.  That's going to take a few days.

5b9b849b45 Trivial changes/forced-commit to document previous change r264050 whose
description was eaten by the dog (or an editor crash or something).

Add variable-frequency support to the arm mpcore eventtimer driver.

This allows a platform's early init code to tell the mpcore driver that the
clock frequency can vary.  That causes the mpcore driver to register an
eventtimer, but not a timecounter.  The platform has to provide a time
counter using some other fixed-frequency clock, but can still use the
per-cpu goodness of the mpcore hardware for event timers.

When the platform support code does something to change the frequency of
the CPU clocks (power saving, thermal management) it must tell the mpcore
driver code about it using arm_tmr_change_frequency().

c878f70aae Disable the timer and clear any pending bit, then setup the new counter
register values, then restart the timer.  This prevents a situation where
an old event fires just as we're about to load a new value into the timer,
when the start routine is called to change the time of the current event.

Also re-nest the parens properly for casting the result of converting
time and frequency to a count.  This doesn't actually change the result of
the calcs, but will some day prevent a loss-of-precision warning on the
assignment, if that warning gets enabled.

9e24f23880 Fix build breakage. Apparently all ARM configs build kern_et.c, but only a
few of them also build kern_clocksource.c.  That strikes me as insane, but
maybe there's a good reason for it.  Until I figure that out, un-break
the build by not referencing functions in kern_clocksource if NO_EVENTTIMERS
is defined.

07a5254736 Use 2K buffers for IO to help achieve full device speed, rather than the
default wMaxPacketSize (64 or 512 bytes).  This actually helps older FTDI
devices (which were USB 1/full speed) more than the new H-series high
speed, but even for the new chips it helps cut the number of interrupts
when doing very high speed (3-12mbaud).

cbc0e08a7b Add a new release build variable, WITH_COMPRESSED_IMAGES.
When set to a non-empty value, the installation medium is
compressed with gzip(1) as part of the 'install' target in
the release/ directory.

With gzip(1) compression, downloadable image are reduced in
size quite significantly.  Build test against head@263927
shows the following:

 bootonly.iso:		64% smaller
 disc1.iso:		44% smaller
 memstick.img:		47% smaller
 mini-memstick.img:	65% smaller
 dvd1.iso:		untested

This option is off by default, I would eventually like to
turn it on by default, and remove the '-k' flag to gzip(1)
so only compressed images are published on FTP.
