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.

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

bootstage: Provide a separate record count setting for SPL

2017-09-16T06:57:44+00:00

With SPL we often have limited memory and do not need very many bootstage
records. Add a separate Kconfig option for SPL.

bootstage: Drop unused options

2017-09-16T06:57:44+00:00

The CONFIG_BOOTSTAGE_USER_COUNT option is no-longer needed since we can now
support any number of user IDs. Also BOOTSTAGE_ID_COUNT is not needed now.

Drop these unused options.

bootstage: Adjust to use const * where possible

2017-06-05T18:13:08+00:00

There are a few places that should use const *, such as
bootstage_unstash(). Update these to make it clearer when parameters are
changed.

bootstage: Tidy up error return values

2017-06-05T18:13:08+00:00

We should return a proper error number instead of just -1. This helps the
caller to determine what when wrong. Update a few functions to fix this.

bootstage: Support relocating boostage data

2017-06-05T18:13:06+00:00

Some boards cannot access pre-relocation data after relocation. Reserve
space for this and copy it during preparation for relocation.

bootstage: Use rec_count as the array index

2017-06-05T18:13:05+00:00

At present bootstage has a large array with all possible bootstage IDs
recorded. It adds times to the array element indexed by the ID. This is
inefficient because many IDs are not used during boot. We can save space
by only recording those IDs which actually have timestamps.

Update the array to use a record count, which increments with each
addition of a new timestamp. This takes longer to record a time, since it
may involve an array search. Such a search may be particularly expensive
before relocation when the CPU is running slowly or the cache is off. But
at that stage there should be very few records.
