b75d8dc564 treewide: convert bd_t to struct bd_info by coccinelle
The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:

  It's a **mistake** to use typedef for structures and pointers.

Besides, using typedef for structures is annoying when you try to make
headers self-contained.

Let's say you have the following function declaration in a header:

  void foo(bd_t *bd);

This is not self-contained since bd_t is not defined.

To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>

  #include <asm/u-boot.h>
  void foo(bd_t *bd);

Then, the include direcective pulls in more bloat needlessly.

If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:

  struct bd_info;
  void foo(struct bd_info *bd);

Right, typedef'ing bd_t is a mistake.

I used coccinelle to generate this commit.

The semantic patch that makes this change is as follows:

  <smpl>
  @@
  typedef bd_t;
  @@
  -bd_t
  +struct bd_info
  </smpl>

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_OMAP_HSMMC/CONFIG_MMC_OMAP_HS/g
s/CONFIG_MXC_MMC/CONFIG_MMC_MXC/g
s/CONFIG_MXS_MMC/CONFIG_MMC_MXS/g
s/CONFIG_TEGRA_MMC/CONFIG_MMC_SDHCI_TEGRA/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

e6469f390f imx: mx27 move GPIO_PORTx to gpio.h
These GPIO_PORTx macros should be in gpio.h, but not in imx-regs.h.

Also, imx-regs.h and iomux-v3.h has same macro defintion for
GPIO_PORTx, and both of them are included in mxc_i2c.c(include
mxc_i2c.h). This will incur build warnings with macro redefinition.

Since iomux-v3.h is not compatible with mx27, we can not simply
include iomux-v3.h for mx27, so move the GPIO_PORTx to gpio.h to
fix the build warning.

IIM:
 - Homogenize prg_p naming (the reference manuals are not always self-consistent

 - Add missing SCSx and bank registers.
 - Fix the number of banks on i.MX53.

OCOTP:
 - Rename iim to ocotp in order to avoid confusion.
 - Rename fuse_data to read_fuse_data, and sticky to sw_sticky, according to the
   reference manual.
 - Merge the existing spinoff gp1 fuse definition on i.MX6.
 - Fix the number of banks on i.MX6.

The i.MX28 is omitted because its architecture is a bit different (like imx/mxc

fa47a28661 mmc: access mxcmmc from mx31 boards
This patch modifies mxcmmc.c to be used
not only by i.MX27 but also by i.MX31 boards.
Both use the same SD controller, but have different
clock set-ups.
The i.MX27 imx_get_XXXclock functions are made static to
generic.c and a public mxc_get_clock() function
is provided.  Pins, base address and prototypes for
an i.MX31 specific board_init_mmc() are provided.
Some of the i.MX27 clock getters are unused and marked
as such to avoid warnings (./MAKEALL -s mx27), but
the code was left in for future use.
