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.

sh: Do not provide strncmp

2018-02-22T23:06:05+00:00

With modern GCC, we get warnings such as:
cmd/jffs2.c: In function 'mtdparts_init':
arch/sh/include/asm/string.h:110:38:
warning: array subscript is above array bounds [-Warray-bounds]
   : "0" (__cs), "1" (__ct), "r" (__cs+__n)
                                  ~~~~^~~~

This results in a small size reduction as well.

sh: Use asm-generic/io.h

2017-10-03T01:52:21+00:00

Convert the sh architecture to make use of the new asm-generic/io.h to
provide address mapping functions. As the generic implementations are
suitable for sh this is primarily a matter of moving code.

Feedback from architecture maintainers is welcome.

sh4: remove __io config options from r2dplus and r7780mp boards

2016-12-03T02:32:44+00:00

Defined __io is no-op for the SH architecture and it can be removed
from board files without any functional change.

sh4: cache: move exported cache manipulation functions into cache.c

2016-12-03T02:32:42+00:00

No functional change, moving cache manipulation functions into cache.c
allows to collect all of them in a single location and as a pleasant
side effect cache_control() function can be unexported now.

efi: Use asmlinkage for EFIAPI

This is required for x86 and is also correct for ARM (since it is empty).

Remove arch/${ARCH}/include/asm/errno.h

2016-09-23T21:56:18+00:00

Unlike Linux, nothing about errno.h is arch-specific in U-Boot.
As you see, all of arch/${ARCH}/include/asm/errno.h is just a
wrapper of .  Actually, U-Boot does not
export headers to user-space, so we just have to care about the
consistency in the U-Boot tree.

Now all of include directives for  are gone.
Deprecate .

These defines are valid only when iomem_valid_addr is defined,

sh: Drop the arch-specific board init

It is well past the deadline for conversion to generic board init. Remove
the old code.

Please test this and perhaps send a follow-up patch if needed.
