Move all command code into its own directory

2016-01-25T15:39:43+00:00

There are a lot of unrelated files in common, including all of the commands.
Moving them into their own directory makes them easier to find and is more
logical.

Some commands include non-command code, such as cmd_scsi.c. This should be
sorted out at some point so that the function can be enabled with or without
the associated command.

Unfortunately, with m68k I get this error:

m68k:  +   M5329AFEE
+arch/m68k/cpu/mcf532x/start.o: In function `_start':
+arch/m68k/cpu/mcf532x/start.S:159:(.text+0x452): relocation truncated to fit: R_68K_PC16 against symbol `board_init_f' defined in .text.board_init_f section in common/built-in.o

I hope someone can shed some light on what this means. I hope it isn't
depending on the position of code in the image.

mmc: store hwpart in the block device

2016-01-14T02:05:19+00:00

This will allow us to have multiple block device structs each referring
to the same eMMC device, yet different HW partitions.

For now, there is still a single block device per eMMC device. As before,
this block device always accesses whichever HW partition was most recently
selected. Clients wishing to make use of multiple block devices referring
to different HW partitions can simply take a copy of this block device
once it points at the correct HW partition, and use each one as they wish.
This feature will be used by the next patch.

In the future, perhaps get_device() could be enhanced to return a
dynamically allocated block device struct, to avoid the client needing to
copy it in order to maintain multiple block devices. However, this would
require all users to be updated to free those block device structs at some
point, which is rather a large change.

Most callers of mmc_switch_part() wish to permanently switch the default
MMC block device's HW partition. Enhance mmc_switch_part() so that it does
this. This removes the need for callers to do this. However,
common/env_mmc.c needs to save and restore the current HW partition. Make
it do this more explicitly.

Replace use of mmc_switch_part() with mmc_select_hwpart() in order to
remove duplicate code that skips the call if that HW partition is already
selected.

block: pass block dev not num to read/write/erase()

2016-01-14T02:05:18+00:00

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.

common: mmc: unsigned char compared against 0

2015-12-05T23:22:24+00:00

"enable" is unsigned char type and its value will not be
negative, so discard "enable < 0".

Move console definitions into a new console.h file

2015-11-20T03:27:50+00:00

The console includes a global variable and several functions that are only
used by a small subset of U-Boot files. Before adding more functions, move
the definitions into their own header file.

mmc: Implement SD/MMC versioning properly

2015-02-23T17:34:29+00:00

The SD/MMC version scheme was buggy when dealing with standard
major.minor.change cases. Fix it by using something similar to
the linux's kernel versioning method.

mmc: extend mmcinfo output to show partition write reliability settings

2015-01-19T15:41:51+00:00

This extends the mmcinfo hardware partition info output to show
partitions with write reliability enabled with the "WRREL" string.
If the partition does not have write reliability enabled the "WRREL"
string is omitted; this is analogous to the ehhanced attribute.

Example output:

mmc: extend the mmc hwpartition sub-command to change write reliability

2015-01-19T15:41:51+00:00

This change extends the mmc hwpartition sub-command to change the
per-partition write reliability settings. It also changes the
syntax used for the enhanced user data area slightly to better
accomodate the write reliability option.

mmc: add mmc hwpartition sub-command to do eMMC hardware partitioning

2015-01-19T15:41:51+00:00

Adds the mmc hwpartition sub-command to perform eMMC hardware
partitioning on an mmc device. The number of arguments can be
large for a complex partitioning, but as the partitioning has
to be done in one go it is difficult to make it simpler.

mmc: show the erase group size and HC WP group size in mmcinfo output

2015-01-19T15:04:46+00:00

This adds the erase group size and high-capacity WP group size to
mmcinfo's output. The erase group size is necessary to properly align
erase requests on eMMC. The high-capacity WP group size is necessary
to properly align partitions on eMMC.
