treewide: fix up files incorrectly marked executable

Inspired by the following kernel commit:

"commit 90fda63fa1156ec1bcfd7f9ca384cec221f70a21

treewide: fix up files incorrectly marked executable

Joe Perches noted that we have a few source files that for some
inexplicable reason (read: I'm too lazy to even go look at the history)
are marked executable:

drivers/gpu/drm/amd/amdgpu/vce_v4_0.c
drivers/net/ethernet/cadence/macb_ptp.c

A simple git command line to show executable C/asm/header files is this:

   git ls-files -s '*.[chsS]' | grep '^100755'

and then you can fix them up with scripting by just feeding that output
into:

  | cut -f2 | xargs chmod -x

and commit it.

Which is exactly what this commit does.

Christophe Leroy [Fri, 16 Mar 2018 16:20:53 +0000 (17:20 +0100)]
common: env_embedded: allow fine placement of environment object

Commit 7653942b10e9e ("common/env_embedded.c: drop support for
CONFIG_SYS_USE_PPCENV") dropped the .ppcenv section which was
used in linking scripts to allow fine placement of embedded
environment sections.

This implies that GCC randomly places objects from env/embedded.o
and environment is not guaranteed to be located at the correct address:

04003df8 g     F .text  00000038 mii_init
04004000 g     O .text  00000004 env_size
04004004 g     O .text  00002000 environment
04006004 g     F .text  00000040 .hidden __lshrdi3

This patch restores this capability by allocating each object marked
with __UBOOT_ENV_SECTION__ into a different section. Hence
'environment' will be alone in .text.environment, allowing a
fine placement in u-boot.lds with:

. = DEFINED(env_offset) ? env_offset : .;
env/embedded.o (.text.environment)
