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.

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.

net: Move enetaddr env access code to env config instead of net config

2018-04-09T03:00:58+00:00

In order that we can use eth_env_* even when CONFIG_NET isn't set, move
these functions to environment code from net code.

This fixes failures such as:

  board/ti/am335x/built-in.o: In function `board_late_init':
  board/ti/am335x/board.c:752: undefined reference to `eth_env_set_enetaddr'
  u-boot/board/ti/am335x/board.c:766: undefined reference to `eth_env_set_enetaddr'

which caters for use cases such as:

commit f411b5cca48f ("board: am335x: Always set eth/eth1addr environment
variable")

when Ethernet is required in Linux, but not U-Boot.

powerpc: mpc8xx: cleaning up watchdog

2018-04-06T20:30:37+00:00

In preparation of migration to DM watchdog, clean up a bit.

The 8xx watchdog really is a HW watchdog, so declare it as is
then it goes through Kconfig

And the watchdog reset doesn't mind getting interrupted, so
no need to disable interrupts

powerpc: mpc8xx: refactorise reginfo

2018-04-06T20:30:37+00:00

reginfo is redundant with some of the commands in immap.c, so
move reginfo into that file and remove duplicated info.

powerpc: mpc8xx: initialisation of initial RAM

2018-04-06T20:30:37+00:00

u-boot requires some RAM at startup, to store global data structure.
RAM is also needed when we migrate to DM for some initial malloc

This patch implements the proper init of that RAM by calling
board_init_f_alloc_reserve() and board_init_f_init_reserve()

powercp: mpc8xx: move commproc.h

2018-04-06T20:30:37+00:00

powerpc: mpc8xx: Change CONFIG_8xx to CONFIG_MPC8xx

2018-04-06T20:30:37+00:00

CONFIG_8xx doesn't mean much outside of arch/powerpc/
This patch renames it CONFIG_MPC8xx just like CONFIG_MPC85xx etc ...
It also renames 8xx_immap.h to immap_8xx.h to be consistent with
other file names.

powerpc: mpc8xx: remove get_immr() argument

2018-04-06T20:30:37+00:00

get_immr() is always called with 0 as an argument, so it is useless.
