When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.Signed-off-by: Tom Rini

For debugging efi_loader we need the capability to print EFI
device paths. With this patch we can write:debug("device path: %pD", dp);
A possible output would be
device path: /MemoryMapped(0x0,0x3ff93a82,0x3ff93a82)
This enhancement is not available when building without EFI support
and neither in the SPL nor in the API example.A test is provided. It can be executed in the sandbox with command
ut_print.The development for EFI support in the sandbox is currently in
branch u-boot-dm/efi-working. The branch currently lacks
commit 6ea8b580f06b ("efi_loader: correct DeviceNodeToText
for media types"). Ater rebasing the aforementioned branch on
U-Boot v2018.01 the test is executed successfully.Without EFI support in the sandbox the test is simply skipped.

This works (roughly) the same way as linux's, but we currently always
print lower-case (ie. we just keep %pUB and %pUL for compat with linux),
mostly just because that is what uuid_bin_to_str() supports.%pUb: 01020304-0506-0708-090a-0b0c0d0e0f10
%pUl: 04030201-0605-0807-090a-0b0c0d0e0f10It will be used by a later efi_loader paths for efi variables and for
device-path-to-text protocol, and also quite useful for debug prints
of protocol GUIDs.Signed-off-by: Rob Clark

AVR32 is gone. It's already more than two years for no support in Buildroot,
even longer there is no support in GCC (last version is heavily patched 4.2.4).Linux kernel v4.12 got rid of it (and v4.11 didn't build successfully).
There is no good point to keep this support in U-Boot either.

We have long had available optimized versions of the memset and memcpy
functions that are borrowed from the Linux kernel. We should use these
in normal conditions as the speed wins in many workflows outweigh the
relatively minor size increase. However, we have a number of places
where we're simply too close to size limits in SPL and must be able to
make the size vs performance trade-off in those cases.Cc: Philippe Reynes

This patch adds a small printf() version that supports all basic formats.
Its intented to be used in U-Boot SPL versions on platforms with very
limited internal RAM sizes.To enable it, just define CONFIG_USE_TINY_PRINTF in your defconfig. This
will result in the SPL using this tiny function and the main U-Boot
still using the full-blown printf() function.This code was copied from:
http://www.sparetimelabs.com/printfrevisited
With mostly only coding style related changes so that its checkpatch
clean.The size reduction is about 2.5KiB. Here a comparison for the db-mv784mp-gp

After consulting with some of the SPDX team, the conclusion is that
Makefiles are worth adding SPDX-License-Identifier tags too, and most of
ours have one. This adds tags to ones that lack them and converts a few

equivalent tag.Cc: Kate Stewart
