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.

1d2c0506d3 mmc: move more driver config options to Kconfig
Move (and rename) the following CONFIG options to Kconfig:

  CONFIG_DAVINCI_MMC  (renamed to CONFIG_MMC_DAVINCI)
  CONFIG_OMAP_HSMMC   (renamed to CONFIG_MMC_OMAP_HS)
  CONFIG_MXC_MMC      (renamed to CONFIG_MMC_MXC)
  CONFIG_MXS_MMC      (renamed to CONFIG_MMC_MXS)
  CONFIG_TEGRA_MMC    (renamed to CONFIG_MMC_SDHCI_TEGRA)
  CONFIG_SUNXI_MMC    (renamed to CONFIG_MMC_SUNXI)

They are the same option names as used in Linux.

This commit was created as follows:

[1] Rename the options with the following command:

find . -name .git -prune -o ! -path ./scripts/config_whitelist.txt \
-type f -print | xargs sed -i -e '
s/CONFIG_DAVINCI_MMC/CONFIG_MMC_DAVINCI/g

s/CONFIG_SUNXI_MMC/CONFIG_MMC_SUNXI/g
'

[2] Commit the changes

[3] Create entries in driver/mmc/Kconfig.
    (copied from Linux)

[4] Move the options with the following command
tools/moveconfig.py -y -r HEAD \
MMC_DAVINCI MMC_OMAP_HS MMC_MXC MMC_MXS MMC_SDHCI_TEGRA MMC_SUNXI

[5] Sort and align drivers/mmc/Makefile for readability

237c36379c ARM: tegra: move NVIDIA common files to arch/arm/mach-tegra
All the Tegra boards borrow the files from board/nvidia/common/
directory, i.e., board/nvidia/common/* are not vendor-common files,
but SoC-common files.

Move NVIDIA common files to arch/arm/mach-tegra/ to clean up
Makefiles.

As arch/arm/mach-tegra/board.c already exists, this commit renames
board/nvidia/common/board.c to arch/arm/mach-tegra/board2.c,
expecting they will be consolidated as a second step.

Add a dm_ prefix to driver model I2C functions so that we can keep the old
ones around.

This is a little unfortunate, but on reflection it is too difficult to

This converts all Tegra boards over to use driver model for I2C. The driver
is adjusted to use driver model and the following obsolete CONFIGs are

   - CONFIG_I2C_MULTI_BUS
   - CONFIG_SYS_MAX_I2C_BUS
   - CONFIG_SYS_I2C_SPEED

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/.

803d01edc2 ARM: tegra: Tegra30 pinmux cleanup
This renames all the pinmux pins, drive groups, and functions so they
have a prefix which matches the type name. These lists are also auto-
generated using scripts that were also used to generate the kernel
pinctrl drivers. This ensures that the lists are consistent between the
two.

The entries in tegra30_pingroups[] are all updated to remove the columns
which are no longer used.

All affected code is updated to match.

This introduces a few changes to pin/group/function naming and the set of
available functions for each pin. The new values now exactly match the
TRM; the chip documentation. I adjusted one entry in
pinmux-config-cardhu.h due to this.

dfb42fc95d ARM: tegra: pinmux naming consistency fixes
Clean up the naming of pinmux-related objects:
* Refer to drive groups rather than pad groups to match the Linux kernel.
* Ensure all pinmux API types are prefixed with pmux_, values (defines)
  are prefixed with PMUX_, and functions prefixed with pinmux_.
* Modify a few type names to make their content clearer.
* Minimal changes to SoC-specific .h/.c files are made so the code still
  compiles. A separate per-SoC change will be made immediately following,
  in order to keep individual patch size down.

5ab502cb89 dts: move device tree sources to arch/$(ARCH)/dts/
Unlike Linux Kernel, U-Boot historically had *.dts files under
board/$(VENDOR)/dts/ and *.dtsi files under arch/$(ARCH)/dts/.

I think arch/$(ARCH)/dts dicretory is a better location
to store both *.dts and *.dtsi files.

For example, before this commit, board/xilinx/dts directory
had both Microblaze dts (microblaze-generic.dts) and
ARM dts (zynq-*.dts), which are totally unrelated.

This commit moves *.dts to arch/$(ARCH)/dts/ directories,
allowing us to describe nicely mutiple DTBs generation in the next commit.

9e4140329e kbuild: change out-of-tree build
This commit changes the working directory
where the build process occurs.

Before this commit, build process occurred under the source
tree for both in-tree and out-of-tree build.

That's why we needed to add $(obj) prefix to all generated
files in makefiles like follows:
  $(obj)u-boot.bin:  $(obj)u-boot

Here, $(obj) is empty for in-tree build, whereas it points
to the output directory for out-of-tree build.

And our old build system changes the current working directory
with "make -C <sub-dir>" syntax when descending into the
sub-directories.

On the other hand, Kbuild uses a different idea
to handle out-of-tree build and directory descending.

The build process of Kbuild always occurs under the output tree.
When "O=dir/to/store/output/files" is given, the build system
changes the current working directory to that directory and
restarts the make.

Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>"
syntax for descending into sub-directories.
(We can write it like "make $(obj)=<sub-dir>" with a shorthand.)
This means the current working directory is always the top
of the output directory.

Also provide a weak symbol for this function, to avoid the

1e2d785975 tegra: fix leftover CONFIG_TEGRA2_MMC & _SPI build switches
Missed some boards after my tegra2_mmc.* -> tegra_mmc.* change, and
one instance of CONFIG_TEGRA2_SPI. MAKEALL -s tegra2 AOK, Seaboard MMC
AOK. Didn't test Tamonten, Paz00 or TrimSlice, as I have none here.

22d58506f5 tegra: Implement gpio_early_init() on Tamonten
The PI4 GPIO is used on Tamonten to reset carrier board peripherals.
Power sequencing hardware on the carrier pulls the reset low before
powering up the Tegra, and the CPU is supposed to signal readiness,
and therefore bring peripherals out of reset by pulling PI4 high.

ed900c55c3 tegra: Rework Tamonten support
This commit uses the common Tegra board implementation instead of
duplicating a lot of the code. In addition, the Plutux and Medcom
specific board files can be removed as the MMC/SD setup is common
among all Tamonten-based boards.
