Currently, only the eMMC OCR/CID/CSD/EXTCSD/RCA/DSR register are

In case the eMMC contains any GP partitions or user sets up new GP

Add option to extend the hardware partition to the maximum size by
using the '-' dash sign instead of $cnt parameter. This is useful
in case we want to switch the entire eMMC user area into pSLC mode,
especially in case the device may be populated with different size
eMMCs. With this change, we do not have to calculate the number of
blocks of the user area manually.
To switch the pSLC mode for user area, use e.g. the following.

The repeatable property is currently attached to the main command and
sub-commands have no way to change the repeatable value (the
->repeatable field in sub-command entries is ignored).
Replace the ->repeatable field by an extended ->cmd() hook (called
->cmd_rep()) which takes a new int pointer to store the repeatable cap
of the command being executed.
With this trick, we can let sub-commands decide whether they are
repeatable or not.
We also patch mmc and dtimg who are testing the ->repeatable field
directly (they now use cmd_is_repeatable() instead), and fix the help
entry manually since it doesn't use the U_BOOT_CMD() macro.

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.
