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

2018-05-07T13:34:12+00:00

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.

mmc: remove hc_wp_grp_size from struct mmc if not needed

2018-01-12T09:11:24+00:00

hc_wp_grp_size is needed only if hardware partitionning is used.
On ARM removing it saves about 30 bytes of code space.

mmc: compile out erase and write mmc commands if write operations are not enabled

2018-01-12T09:11:24+00:00

Also remove erase_grp_size and write_bl_len from struct mmc as they are
not used anymore. On ARM, removing them saves about 100 bytes of code
space in SPL.

mmc: make optional the support for eMMC hardware partitioning

2018-01-12T09:11:04+00:00

Not all boards have an eMMC and not all users have a need for this.
Allow to compile it out. By default it is still included.

mmc: dump card and host capabilities if debug is enabled

2018-01-12T09:11:04+00:00

This is a useful information while debugging the initialization process or
performance issues.
Also dump this information with the other mmc info if the verbose option
is selected

Display the mode name when the user execute 'mmc info'. Also instead of
displaying tran_speed, display the actual bus speed.

blk: Remove various places that do flush cache after read

2017-09-15T12:05:10+00:00

All these places seem to inherit the codes from the MMC driver where
a FIXME was put in the comment. However the correct operation after
read should be cache invalidate, not flush.

The underlying drivers should be responsible for the cache operation.
Remove these codes completely.

cmd_mmc: fix arg parsing for setdsr subcmd

2017-04-12T16:46:38+00:00

The handler do_setdsr receives only the dsr parameter,
the action is parsed before.

Error was introduced when restructuring the mmc command
implementation in commit 1fd93c6e7d8a1e4d6261058cefab11b875ded252.
