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.

1811a928c6 Move most CONFIG_HAVE_BLOCK_DEVICE to Kconfig
config_fallbacks.h has some logic that sets HAVE_BLOCK_DEVICE
based on a list of enabled options.  Moving HAVE_BLOCK_DEVICE to
Kconfig allows us to drastically shrink the logic in
config_fallbacks.h

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.

87b8530fe2 disk: part: implement generic function part_get_info_by_name()
So far partition search by name has been supported only on the EFI partition
table. This patch extends the search to all partition tables.

Rename part_get_info_efi_by_name() to part_get_info_by_name(), move it from
part_efi.c into part.c and make it a generic function which traverses all part
drivers and searches all partitions (in the order given by the linked list).

For this a new variable struct part_driver.max_entries is added, which limits
the number of partitions searched. For EFI this was GPT_ENTRY_NUMBERS.
Similarly the limit is defined for DOS, ISO, MAC and AMIGA partition tables.

2a981dc2c6 dm: block: Adjust device calls to go through helpers function
To ease conversion to driver model, add helper functions which deal with
calling each block device method. With driver model we can reimplement these
functions with the same arguments.

Use inline functions to avoid increasing code size on some boards.

96e5b03c8a dm: part: Convert partition API use to linker lists
We can use linker lists instead of explicitly declaring each function.
This makes the code shorter by avoiding switch() statements and lots of
header file declarations.

While this does clean up the code it introduces a few code issues with SPL.
SPL never needs to print partition information since this all happens from
commands. SPL mostly doesn't need to obtain information about a partition
either, except in a few cases. Add these cases so that the code will be
dropped from each partition driver when not needed. This avoids code bloat.

I think this is still a win, since it is not a bad thing to be explicit
about which features are used in SPL. But others may like to weigh in.

7c4213f6a5 block: pass block dev not num to read/write/erase()
This will allow the implementation to make use of data in the block_dev
structure beyond the base device number. This will be useful so that eMMC
block devices can encompass the HW partition ID rather than treating this
out-of-band. Equally, the existence of the priv field is crying out for
this patch to exist.

75eb82ec7c mflash: Initial mflash support
Mflash is fusion memory device mainly targeted consumer eletronic and
mobile phone.
Internally, it have nand flash and other hardware logics and supports
some different operation (ATA, IO, XIP) modes.

IO mode is custom mode for the host that doesn't have IDE interface.
(Many mobile targeted SoC doesn't have IDE bus)

This driver support mflash IO mode.

Followings are brief descriptions about IO mode.

1. IO mode based on ATA protocol and uses some custom command. (read
   confirm, write confirm)
2. IO mode uses SRAM bus interface.
