When TPL is used on x86 we may want to program the microcode (at least for
the first CPU) early in boot. Add support for this by refactoring the
existing code to be more generic.

In some cases it is useful to add a group of files to the image and be
able to access them at run-time. Of course it is possible to generate
the binman config file with a set of blobs each with a filename. But for
convenience, add an entry type which can do this.

At present if there is only a zero-size entry in a section this is

Add support for compressing blob entries. This can help reduce image sizes

When tools are needed but not present, at present we just get an error

Binman currently supports updating the main device tree with things like
the position of each entry. Extend this support to SPL and TPL as well,
since they may need (a subset of) this information.

Also adjust DTB output files to have a .out extension since this seems
clearer than having a .dtb extension with 'out' in the name somwhere.

Also add a few missing comments and update the DT setup code to use
ReadFile and WriteFile().
Signed-off-by: NSimon Glass <sjg@chromium.org>

We use a fake device tree in tests most of the time since tests don't
normally care about the actual data. For example, for U-Boot proper we use
U_BOOT_DTB_DATA which is just a four-character string. This makes testing
the image output against an expected value very easy.

However in some cases, such as when the test wants to check that the DT
output containing particular nodes, we do actually need the real DT. Add
support for this, along with a command-line option to select 'test mode'.
Signed-off-by: NSimon Glass <sjg@chromium.org>

We always have a device tree for U-Boot proper. But we may also have one
for SPL and TPL. Add a new Entry method to find out what DTs an entry
has, and use that list when updating DTs.
Signed-off-by: NSimon Glass <sjg@chromium.org>

At present we have a few calls to device-tree functions in binman and plan
to add more as we add new entry types which need to report their results.

It makes sense to put this code in a central place so that we can make
sure all device trees are updated. At present we only have U-Boot proper,
but plan to add SPL and TPL too.

Rather than reaching into this module from control, move the code that
needs this info into state.
Signed-off-by: NSimon Glass <sjg@chromium.org>

At present the control module has state information in it, since it is the
primary user of this. But it is a bit odd to have entries and other
modules importing control to obtain this information.

It seems better to have a dedicated state module, which control can use as
well. Create a new module using code from control and update other modules
to use it.

This should be big endian, since that is what device tree uses. Fix it.
Signed-off-by: NSimon Glass <sjg@chromium.org>

At present we require the caller to manually update the device tree using
individual calls to libfdt functions. This is not ideal. It would be
better if we could make changes using the Python structure and then call a
Sync() function to write them back.

Add this feature to the Fdt class. Update binman and the tests to match.

Sometimes it is useful to build only a subset of the images provided by

At present if there are two vblock entries an image their contents are
written to the same file in the output directory. This prevents checking

Xilinx changes for v2018.11

- Handle BOARD_LATE_INIT via Kconfig

SPL:
- Enable GZIP for all partitions types(not only for kernel)

ZynqMP:
- Rearrange pmufw version handling
- Support newer PMUFW with improved fpga load sequence

Zynq:
- Cleanup config file
- Simplify zybo config by enabling option via Kconfig

net:
- Fix gems max-speed property reading
- Enable support for fixed-link phys

Based on dt-specs fixed-link doesn't require phy-handle to be used.
Fix driver to only read phy related setting when phy-handle is found.

Patch queue for efi - 2018-09-26

A lot of goodness in this release. We're *very* close to running the
UEFI Shell and SCT natively. The only missing piece are HII protocols.

  - FAT write support (needed for SCT)
  - improved FAT directory support (needed for SCT)
  - RTC support with QEMU -M virt
  - Sandbox support (run UEFI binaries in Linux - yay)
  - Proper UTF-16 support
  - EFI_UNICODE_COLLATION_PROTOCOL support (for UEFI Shell)
  - EFI_SIMPLE_TEXT_INPUT_EX_PROTOCOL support (for UEFI Shell)
  - Fix window size determination
  - Fix Tegra by explicitly unmapping RAM
  - Clean up handle entanglement
  - Lots of generic code cleanup

When running sandbox with the new pointer sanitization we just recently
introduced, we're running into a case with FIT images where we end up
interpreting pointers as addresses.

What happened is that most callers of set_working_fdt_addr() simply
convert pointers into addresses without taking into account that they
might be 2 separate address spaces. Fix the callers up to map their
pointers into addresses.

This makes sandbox tests pass for me again.

This patch modifies PL bitstream loading sequence as per
latest Xilfpga which supports all variants of bitstream images
generated from vivado and from bootgen. With this new change in
Xilfpga, uboot doesn't need to validate and swap bitstream as it will
be taken care inside Xilfpga. ZynqMP PL driver now checks for supporting
PMUFW version before skipping the validation and swap sequence as there
can be old PMUFW which doesn't supports this feature. In this case, driver
uses old way of PL bitstream loading sequence.
