bootm: fix 'memory-fixup' for vxWorks boot

The check for having a memory node within the fdt blob is made wrong, we
fix this here.

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
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.

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.

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

ARM: bootm: don't assume sp is in DRAM bank 0

2018-01-12T17:12:31+00:00

arch_lmb_reserve() currently assumes that the stack pointer is within DRAM
bank 0. This is not necessarily true. Enhance the code to search through
DRAM banks until the bank that does contain SP is found, and then reserve
the tail of that bank.

env: Rename getenv/_f() to env_get()

2017-08-16T12:30:24+00:00

We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.

Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

The author of the commit discovered later on that this was already being
done in cleanup_before_linux() on arch/arm/cpu/armv7m/cpu.c.

armv7m: Disable D-cache when booting nommu(ARMv7M) Linux kernel

2017-06-10T00:34:54+00:00

Disable D-Cache is required when booting nommu Linux kernel.
(please see Linux kernel source "arch/arm/kernel/head-nommu.S")

U-Boot is enabled D-cache and I-Cache at startup.
However, it does not disable D-Cache before
booting nommu Linux kernel.
Therefore, I call dcache_disable()
when the CPU is ARMv7M to fix this problem.

arm: Add declarations to avoid needing to include headers
