      fel: Add FIT image parsing and loading · 14b3492e
      Andre Przywara authored 
      So far sunxi-fel expects a legacy U-Boot image after the SPL, when
called with the "uboot" command.
This only works for (current) 32-bit builds, which only need one image
to load (U-Boot proper).

64-bit builds also include at least a Trusted Firmware binary, and also
might contain a firmware image for the ARISC management processor. So
we use the more capable FIT image, which can contain multiple images
to load.

Introduce support for that, by adding code to parse a FIT image, find
the image files included, and load them to their respective load
addresses. On the way we keep track of the entry point, that only one of
those images provides, and also note the architecture of this image
(ARMv7 or AArch64).
On top of that we detect which of the images is the actual U-Boot proper
image, and append the chosen DTB to the end of it.

This all mimics the code U-Boot's SPL uses to achieve the same goal when
running from MMC or SPI flash, compare the implementation of
spl_load_simple_fit() in U-Boot's common/spl/spl_fit.c:
https://gitlab.denx.de/u-boot/u-boot/-/blob/master/common/spl/spl_fit.c



This requires the libfdt library for parsing the FIT image (which is in
fact a devicetree blob).

      fel: Check the U-Boot's CRC instead of its size · e753821e
      Maxime Ripard authored 
      

The current code checks that the transferred size is matching the size
reported in the image header.

Unfortunately, the transferred image might be padded, which doesn't change
anything at the functional level, but will make that check trigger since
the actual image will be smaller than the transferred data.

Change that logic to first check that the transferred size isn't less that
the header image size, which will still be an error, and then check for the
CRC of the image itself. This will prove to be an more robust integrity
check than what we have right now anyway.

The CRC used in the image header is the CRC32 algorithm, that is
implemented in the zlib, which is installed on most devices on the planet,
so we can just use that implementation instead of rolling our own.

      tests: Introduce a basic testing framework · 5cbb0c91
      Bernhard Nortmann authored 
      

All tests should go into the new "tests" subdirectory. The idea is
that the separate Makefile in that directory will get invoked via
a top-level "make check".

The tests/Makefile should then take care of running all available
tests, returning an appropriate exit status. Future tests may be
functional, examine code metrics (coverage analysis), or both.

For a start, I'd simply like to check that sunxi-fexc is able to
properly compile all the .fex files from linux-sunxi/sunxi-boards.

(Note: This currently FAILS and will probably require adjustments
to both sunxi-tools and the .fex repository. To work around this,
for now I'm applying patches to fix sunxi-boards.)

      Makefile: Revert sunxi-pio change from 209633ab · 6cd51fe5
      Bernhard Nortmann authored 
      

The previous commit had introduced a new build rule that made
sunxi-pio always (cross-)compile as part of TARGET_TOOLS. This
originated from a misunderstanding, and is wrong - sunxi-pio
should be part of TOOLS instead.

sunxi-pio is a "dual mode" utility. When run natively on a sunxi
SoC, it can mmap() and manipulate the PIO registers directly. But
it also supports file-based operation, to be used in conjunction
with sunxi-fel (after uploading fel-pio.bin thunk code). This
should work over USB from non-sunxi hosts, and thus puts sunxi-pio
in the TOOLS category. See the fel-gpio shell script for details.

      Makefile: Adjust default targets for "make" and "make install" · 5244e88f
      Bernhard Nortmann authored 
      

Fixing the (currently erroneous) compilation of sunxi-pio will
cause "make target-tools" to require a suitable cross-compiler
installed. Otherwise "make target-tools" fails to build.
As that is part of our default target ("make all"), we might
possibly introduce a build breakage on quite a few systems.

Avoid this situation by redefining "make tools" as the default,
and change "make install" to "make install-tools", i.e. limit
the standard targets to those builds that only rely on the host
toolchain. From now, if you actually want to include the cross-
compiling steps, use "make all" or "make install-all" instead.

      Add support for auto-updated version information · 57928140
      Bernhard Nortmann authored 
      

The Makefile will now use a script (autoversion.sh) to update
version.h, which in turn defines a VERSION string and gets
included from common.h.

The idea is that version.h normally receives a git-describe
based identifier that represents the current checkout. In
cases where git might not be available, e.g. for builds from
a tarball, the script will instead fall back to a predefined
version (that should reflect the most recent release tag).

      Add a tool to generate raw NAND images · e25f6e90
      Boris Brezillon authored 
      

Generating raw NAND images is particularly useful for boot0 images
creation since the mainline driver is not supporting the funky layout
used by Allwinner's ROM code to load the boot0 binary from NAND.

This tools also allows one to generate raw images for 'normal' partitions
so that they can be flashed before soldering on the NAND on the board
(using a regular NAND programmer).

The tool takes care of generating ECC bytes and randomizing data as
expected by the NAND controller, and re-arranging the ECC/data sections
correctly.

      Makefile: Add an install rule · 0f691878
      Ian Campbell authored 
      

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.

      Makefile: Split out target tools rules · bf4ec9a0
      Ian Campbell authored 
      

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.

      Makefile: Prefix most tools with sunxi- · f1cb74d8
      Ian Campbell authored 
      

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.

      Add copyright headers to various files. · 227c7e03
      Ian Campbell authored 
      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.
