SPDX: Convert all of our multiple license tags to Linux Kernel style

2018-05-07T14:24:31+00:00

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 multiple licenses (in
these cases, dual license) declared in the SPDX-License-Identifier tag.
In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
as per the Linux Kernel style document.  Note that parenthesis are
allowed so when they were used before we continue to use them.

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

2018-05-07T13:34:12+00:00

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

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.

Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR

2018-04-27T18:54:48+00:00

We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

vxworks: fixed cpu enable using PSCI on armv8

2018-04-13T21:06:05+00:00

Without armv8_setup_psci register VBAR_EL3 is not set up property which
makes SMC calls jump to invalid location.

smp_kick_all_cpus is required to make slave cpus leave gic_wait_for_interrupt.
Without this they will never pursue booting process.

Fix was applied to the two ways of booting VxWorks: bootvx and bootm commands.

This implementation is very similar to what is done in boot_jump_linux
in arch/arm/lib/bootm.c file.

Tested on VxWorks 7 release SR0520 2017-12-08 Intel Stratix 10 SX SoC
Development Kit board.

ARM: Fix Makefile during SPL and TPL build

2018-04-11T17:22:06+00:00

The tiny variants of memset and memcpy implementations can be
built for TPL as well, check whether a TPL build is in progress
and avoid including the default variants.

arm: print information about loaded UEFI images

2018-04-05T13:24:01+00:00

If an exception occurs in a UEFI loaded image we need the start address of
the image to determine the relocation offset.

This patch adds the necessary lines after the registers in the crash dump.
A possible output would be:

UEFI image [0xbffe6000:0xbffe631f] pc=0x138 '/\snp.efi'

With the offset 0x138 we can now find the relevant instruction in the
disassembled 'snp.efi' binary.

libfdt: move headers to and

2018-03-05T15:16:28+00:00

Thomas reported U-Boot failed to build host tools if libfdt-devel
package is installed because tools include libfdt headers from
/usr/include/ instead of using internal ones.

This commit moves the header code:
  include/libfdt.h         -> include/linux/libfdt.h
  include/libfdt_env.h     -> include/linux/libfdt_env.h

and replaces include directives:
  #include       -> #include 
  #include   -> #include

arm64: show_regs: Dump the LRs HW values

2018-02-23T15:40:51+00:00

These were dropped in [1], after relocation, for their values offset by
reloc_off.
Unconditionally show the HW values and add a '(reloc)' hint for the
offset values showed after relocation.
Also, the LRs' dumps are now formatted the same way the other regs' are.

arm/PSCI: support PSCI versions greater than 1.0

2018-02-14T17:14:15+00:00

ATF recently began announcing PSCI v1.1. Since that version is unknown
to u-boot, the PSCI device nodes were not updated.

Switch from the case statement to a greater/less-than comparison so that
v1.1, as well as future versions, get at least the compatible nodes of
known versions.

PSCI v1.1 doesn't seem to have introduced a new corresponding compatible.

ARM: image: indent with tab instead of 4 spaces

Commit 6808ef9ac2a6 ("move booti_setup to arch/arm/lig/image.c")
not only moved the code, but also replaced a tab with 4 spaces
to break the Linux coding style.

Restore tab indentation.
