The nand-part.c code tries to re-read the partition tables
by issuing an ioctl(fd, BLKRRPART, NULL). This isn't available
on non-Linux platforms, e.g. Mac OS X.

Add preprocessor conditionals to prevent this from breaking
the build.

For Linux, this requires additional #defines, see
https://gist.github.com/panzi/6856583#gistcomment-1656524



Placing those #defines into portable_endian.h would mean we
depend on the specific order of #includes (whatever pulls
in endian.h first, including other system includes). Avoid
this by using symbols provided "globally" via the Makefile.

Also nuke the _NETBSD_SOURCE definition in fel.c

Our previous include file only supplied a very limited set of
wrapper redefinitions for platforms that define __APPLE__ (i.e.
Mac OS). In particular, some needed big endian conversions were
missing, causing "symbol(s) not found" errors when linking.

Instead of patching the existing file, let's do away with it
completely and replace it by something more sophisticated.
The portable_endian.h used is in the public domain, and was
taken from https://gist.github.com/panzi/6856583

Commit 472ac475

 introduced
a possible regression by relying on the availability of
libusb_strerror(). There are libusb versions out there _not_
offering this function, which breaks compilation.

Introducing a separate helper function allows us to work around
this, refactor existing code and have more streamlined error
reporting - avoiding the message string retrieval where needed.
The usb_error() function can also optionally abort execution
with a given exit code.

When declaring 'signed' values for section count and version
information in the script_bin_head structure, testing them to be

as 'negative' values like in "fexc-bin: script.bin: version:

Commit d99d59c0

 introduces a bug when the "spl" command is used with a
file that contains a U-Boot binary. "spl" will now try to execute it,
while it's not supposed to. (The command should only start the SPL.)

This patch brings back the `uboot_autostart` flag, which is meant to
remain `false` for the "spl" command, and gets set by "uboot" only.

This patch adds an "echo-gauge" command that is intended for use with
sunxi-fel's output piped into the dialog utility. "echo-gauge" will
output its string argument in a way that updates (i.e. overwrites)
the prompt text that dialog displays, so it's possible to change that
inbetween file transfers from sunxi-fel.

Example:
	sunxi-fel uboot ${UBOOT} \
		echo-gauge "Uploading kernel (1/2)" \
		write-with-gauge 0x42000000 ${KERNEL} \
		write 0x43100000 ${SCRIPT} \

This patch moves some code out of the "write" handler, with the intention
to reuse it later for similar commands.

At the same time, it also discards the previous transfer rate output when
using "-v", as that has become redundant with the 'progress bar' display

This patch adds a boolean parameter "progress" to several functions.
When set (true), it will cause usb_bulk_send() to notify the progress
framework, using progress_update() to convey the current transfer
status.

The feature gets enabled for the "write" command, and is forced
inactive in most other places, e.g. aw_fel_write_uboot_image().
Also, we specifically want the internal use of aw_fel_write() to
never use it.

This patch introduces a new function aw_write_buffer() to
allow a better distinction between FEL write operations.

aw_fel_write() is meant for "privileged" internal use, while
aw_write_buffer() now represents the preferred entry point
for user code like the "write", "fill" or "clear" commands.

There is some deliberate code duplication here that makes sense
when combined with the next patch, where the aw_usb_write()
call will differ. We want aw_fel_write() to enforce no progress
update/callback, while aw_write_buffer() will (optionally)
support it.

When the CPU clock speed is set to 480 MHz by the U-Boot SPL,
the performance of 'sunxi-fel write' transfers to DRAM improves
from ~95 KB/s to ~510 KB/s.

When the CPU clock speed is set to 1008 MHz by the U-Boot SPL,
the performance of 'sunxi-fel write' transfers to DRAM improves
from ~180 KB/s to ~510 KB/s.

This means that the CPU is not a bottleneck for FEL transfers
anymore. Further performance improvements are possible by
increasing the AHB1 clock speed in the U-Boot SPL (up to
something like ~900 KB/s).

The BROM in newer SoC variants doesn't enable MMU by default anymore.
So in order to benefit from e4b3da2b


("fel: Faster USB transfers via 'fel write' to DRAM"), we need to
be able to enable it from the 'sunxi-fel' tool.

This patch can be interpreted as simply reverting the changes done
by Allwinner and bringing back the MMU support in roughly the same
way as it was before. That's why the values in the hardware
registers and the translation table entries replicate the A20 setup.

Additionally, the code is now more defensive and introduces new
"canary" checks for certain known magic values in the coprocessor
registers in order to safeguard against any unpleasant surprises.

MMU tuning for A80 and A64 will probably need a more sophisticated
setup with a second level page table. Because both the SRAM and
the BROM reside in the same 1MB section there and we need finer
granularity. In other words, enabling the MMU on A80 and A64 is
not supported yet.

Allow for separate installation of tools and target-tools, to aid in packaging.

By default everything the tools are installed into /usr/local/bin but this can
be overridden using PREFIX= or BINDIR= on the make invocation.

To enable this it was necessary to split fex2bin and bin2fex out from $(TOOLS)
into $(FEXC_LINKS), because install(1) does not seem to have a mode which
preserves symlinks so it needs to be done separately.

Target tools are those which are only useful on a target sunxi system (i.e.
which probe hardware etc).

Currently this is only sunxi-pio. At first I thought sunxi-nand-part might be
included, but I think that is useful on NAND images as well as actual devices.

This will allow for easier packaging, by letting packagers only include the
target tools when building for a suitable ARM architecture.
