73d7aec0b1 net: smc911x: Drop the standalone EEPROM example
Drop the example, for two reasons. First, it is tapping directly into
the IO accessors of the SMC911x, while it should instead go through
the net device API. Second, this makes conversion of the SMC911x driver
to DM real hard.

0914011310 command: Remove the cmd_tbl_t typedef
We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.

90526e9fba common: Drop net.h from common header
Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.

Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.

f0d73f5cd0 net: smc911x: Drop weak alias from 32bit accessors
These accessors are not overridden by any board, and even if they were,
this is something which should be handled via DM now, so remove the
weak alias option. Moreover, drop the inline keyword, as the compiler

eb46efa381 net: smc911x: Inline all functions from header file
Inline all the functions from the header file, as they are not used
outside of the driver or the standalone EEPROM example.

Note that this does introduce considerable amount of duplication in
the standalone EEPROM example, however that one has to be rewritten
anyway, roughly such that the SMC911x driver would expose DM EEPROM
interface and the standalone example would use that.

587e4a4296 kconfig / kbuild: Re-sync with Linux 4.19

c16b137e49 kbuild: add .SECONDARY special target to scripts/Kbuild.include
Based on the following Linux commits:

 - 54a702f70589 ("kbuild: mark $(targets) as .SECONDARY and remove
   .PRECIOUS markers")

 - 8e9b61b293d9 ("kbuild: move .SECONDARY special target to
   Kbuild.include")

GNU Make automatically deletes intermediate files that are updated
in a chain of pattern rules.

Example 1) %.dtb.o <- %.dtb.S <- %.dtb <- %.dts
Example 2) %.o <- %.c <- %.c_shipped

A couple of makefiles mark such targets as .PRECIOUS to prevent Make
from deleting them, but the correct way is to use .SECONDARY.

  .SECONDARY
    Prerequisites of this special target are treated as intermediate
    files but are never automatically deleted.

  .PRECIOUS
    When make is interrupted during execution, it may delete the target
    file it is updating if the file was modified since make started.
    If you mark the file as precious, make will never delete the file
    if interrupted.

Both can avoid deletion of intermediate files, but the difference is
the behavior when Make is interrupted; .SECONDARY deletes the target,
but .PRECIOUS does not.

The use of .PRECIOUS is relatively rare since we do not want to keep
partially constructed (possibly corrupted) targets.

.SECONDARY with no prerequisites causes all targets to be treated as
secondary. This agrees the policy of Kbuild.

scripts/Kbuild.include seems a suitable place to add it because it is
included from almost all sub-makes.

f8c987f8f1 lib: Add hexdump

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

256060e425 vsprintf.c: add EFI device path printing
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 6ea8b580f0 ("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.

22ada0c8e6 vsprintf.c: add GUID printing
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-0b0c0d0e0f10

It 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.

We need to go further and convert to Kconfig, but it
turned out, nobody is interested anymore in mpc5xxx,
so remove it.

40d5534cff ARM: Default to using optimized memset and memcpy routines
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.

7d9cde1031 lib/tiny-printf.c: Add tiny printf function for space limited environments
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
(Marvell AXP) SPL:

Without this patch:
  58963   18536    1928   79427   13643 ./spl/u-boot-spl

With this patch:
  56542   18536    1956   77034   12cea ./spl/u-boot-spl

Note:
To make it possible to compile tiny-printf.c instead of vsprintf.c when
CONFIG_USE_TINY_PRINTF is defined, the functions printf() and vprintf() are
moved from common/console.c into vsprintf.c in this patch.

da58dec866 Various Makefiles: Add SPDX-License-Identifier tags
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
that had full (or in one case, very partial) license blobs into the
equivalent tag.

When building a Thumb-1-only target with CONFIG_SYS_THUMB_BUILD,
some files fail to build, most of the time because they include
mcr instructions, which only exist for Thumb-2.

This patch introduces a Kconfig option CONFIG_THUMB2 and uses
it to select between Thumb-2 and ARM mode for the aforementioned
files.

49cad54788 Export redesign
this is an atempt to make the export of functions typesafe.
I replaced the jumptable void ** by a struct (jt_funcs) with function pointers.
The EXPORT_FUNC macro now has 3 fixed parameters and one
variadic parameter
The first is the name of the exported function,
the rest of the parameters are used to format a functionpointer
in the jumptable,

the EXPORT_FUNC macros are expanded three times,
1. to declare the members of the struct
2. to initialize the structmember pointers
3. to call the functions in stubs.c
