This is a universal bootable image, which just prints a hello
message on UART0. For example, it is useful as a test payload
when debugging the SPI boot functionality:
   https://linux-sunxi.org/Bootable_SPI_flash

Changes in v2:
 - A workaround for https://patchwork.ozlabs.org/patch/622173
 - Also print the type of the used bootable media

Changes in v3:
 - Bernhard Nortmann's workaround for
   https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63803

Add DISCARD directives to the linker scripts and also -marm option
to GCC command line. Without this, certain toolchains may build
Thumb2 code by default. Also junk sections may be present in the
final binary and they need to be removed.

This helps at least when using the following Linaro toolchain:
gcc-linaro-5.1-2015.08-x86_64_arm-linux-gnueabihf.tar.xz

"make binfiles" should allow building ARM binaries more easily.

Factor out common $(ARM_ELF_FLAGS).

Also rewrite some rules using $< and $@, to avoid repeating
filenames. And trim down on the number of rules using patterns
for objcopy (%.elf -> %.bin) and mksunxiboot (%.bin -> %.sunxi).

After eliminating all warnings, we can disallow them for future
builds. This is done by passing an additional "-Werror" flag
from the Travis build step. Introducing new warnings will cause
a (CI) build failure from now on.

Commit 73c20eea

 removed that symbol
from fel.c - this adds it back (in the Makefile) to address #22.

Caveat: This probably requires you to use "make OS=NetBSD". I have
currently no way of testing it; we're only checking Linux and OSX
builds.

We'll be testing both gcc and clang builds on Linux. As for now,
Travis CI only supports clang for OSX - so exclude gcc currently.

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

This patch adds two new source files that will deal with code
related to progress callbacks and display. I have decided to
keep this separate, as there will be many smaller routines
involved, which otherwise would bloat fel.c unnecessarily.

For starters, let's also move the gettime() function there.

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.

Supports DESTDIR to allow for convenient installation into a staging dir for
distro packaging convenience.

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.

Several of the tools here are too generic and/or short for distro packaging
purposes (which like to try and avoid naming clashes in $PATH). Prefix the
following with "sunxi-":
  - fexc
  - bootinfo
  - fel
  - pio
  - meminfo

Do not prefix any of the fel "payloads" or raw binaries since they would not
normally be installed in $PATH.

Do not prefix "phoenix_info", since "phoenix" already seems like an appropriate
prefix for this particular tool.

Update in-tree callers, README and .gitignore accordingly.

I'd like to package sunxi-tools for Debian and therefore it is important for
the licensing information to be complete/accurate. I believe the intention was
for everything here to be GPL2+ by default, since that is the license on every
file which has one and COPYING contains GPL2.

Early on the license applied to this repo was GPLv3 however this was changed to
GPL2+ by Alejandro in 79ea14d4 at which point he had been the only
contributor.

This patch adds the standard GPL2+ stanza used already in sunxi-tools.git or
the MIT license stanza when requested by the copyright holder to various files
which were missing one as follows:

adb-devprobe.sh
fel-gpio
    According to git all of these were written by Henrik. Copyright years
    according to git. Henrik requested that these be put under an MIT license,
    so that is what has been done.

boot_head.lds
fel-pio.lds
fel-sdboot.lds
jtag-loop.lds
    According to git all of these were written by Henrik. Copyright years
    according to git. According to Henrik "These linker scripts are all GPLv2+
    as the C / ASM sources they refer to".

include/endian_compat.h
    The content of this file was originally added to fel.c (commit
    c71ff92c), which had a GPL2+ stanza at the time, by Eric Molitor and later
    those lines were moved by Alejandro (commit bcde0fc7) into this file.
    I originally added GPL2+ from fel.c and added Eric's copyright with the
    correct year according to git but Eric said "Ack but also would prefer
    MIT/Dual :)", so it has now been changed to MIT.

include/types.h:
    Henrik originally added some of these lines to bootinfo.c, along with a
    GPL2+ stanza, in the original version (commit c26e5ff8). Later on
    Alejandro moved them into this file (commit 329a13ed

) and added more.
    I've copied the stanza from bootinfo.c and added both copyrights with the
    years according to git. Authors:
      Henrik, who says "OK".
      Alejandro Mery

Makefile:
    GPL2+ with copyrights and years according to git. Authors are:
      Alejandro Mery
      Henrik Nordstrom, who says "Yes"
      Pat Wood, who says "Fine with me"

usb-boot:
    Henrik is the primary author, added MIT license on Henrik's request with
    his copyright and years according to git. Authors are:
      Henrik Nordstrom, who says "Yes, that too should be MIT"
      Alejandro Mery (typo fix)
      Michal Suchanek (typo fix)

Everyone affected by the above is CCd.

This probably seems pretty obvious to most people, sorry for being so pedantic
about it. It will save hassel when it comes to getting it into Debian though.

v2: Gathered feedback from the authors
 - Pat said "Fine with me"
 - Henrik asked that adb-devprobe.sh, fel-gpio and usb-boot be MIT, acked
   *.lds, types.h and Makefile
 - Explicitly listed authors of Makefile and usb-boot
 - Michal Suchanek make a typo fix to usb-boot but wasn't CCd, sorry.
 - Reworded commit message due to some bits now being MIT on request of the
   author.
