83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

Enable DM_SPI for atmel SPI driver on taurus board.

Kept few functions related to non-dm and gpio on board
files for reference and will be remove once code moved
to relevant drivers.

      mtd: nand: Rename nand.h into rawnand.h

      We are planning to share more code between different NAND based
      devices (SPI NAND, OneNAND and raw NANDs), but before doing that
      we need to move the existing include/linux/mtd/nand.h file into
      include/linux/mtd/rawnand.h so we can later create a nand.h header
      containing all common structure and function prototypes.

00caae6d47 env: Rename getenv/_f() to env_get()
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.

4614b89134 ARM: at91: move board select menu and common settings
The board select menu in arch/arm/Kconfig is still big.
To slim down it, this commit moves AT91 boards to
arch/arm/mach-at91/Kconfig.
Also, consolidate "config SYS_SOC" in each board Kconfig.

The Kconfig files under board/ directory were modified with the
following command:

    find board -name Kconfig | xargs sed -i -e '
    /config SYS_SOC/ {
        N
        /default "at91"/ {
            N
            d
        }
    }

2e07c249a6 kconfig: arm: introduce symbol for ARM CPUs
This commit introduces a Kconfig symbol for each ARM CPU:
CPU_ARM720T, CPU_ARM920T, CPU_ARM926EJS, CPU_ARM946ES, CPU_ARM1136,
CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100.
Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected
for CPU_ARM1176 and CPU_V7.

For each target, the corresponding CPU is selected and the definition of
SYS_CPU in the corresponding Kconfig file is removed.

Also, it removes redundant "string" type in some Kconfig files.

93d4334f7f Add board MAINTAINERS files
We have switched to Kconfig and the boards.cfg file is going to
be removed. We have to retrieve the board status and maintainers
information from it.

The MAINTAINERS format as in Linux Kernel would be nice
because we can crib the scripts/get_maintainer.pl script.

After some discussion, we chose to put a MAINTAINERS file under each
board directory, not the top-level one because we want to collect
relevant information for a board into a single place.

TODO:
Modify get_maintainer.pl to scan multiple MAINTAINERS files.

dd84058d24 kconfig: add board Kconfig and defconfig files
This commit adds:
 - arch/${ARCH}/Kconfig
    provide a menu to select target boards
 - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
    set CONFIG macros to the appropriate values for each board
 - configs/${TARGET_BOARD}_defconfig
    default setting of each board

(This commit was automatically generated by a conversion script
based on boards.cfg)

In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.

But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.
