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:

Device: OMAP SD/MMC
Manufacturer ID: fe
OEM: 14e
Name: MMC16
Tran Speed: 52000000
Rd Block Len: 512
MMC version 4.41
High Capacity: Yes
Capacity: 13.8 GiB
Bus Width: 4-bit
Erase Group Size: 8 MiB
HC WP Group Size: 16 MiB
User Capacity: 13.8 GiB ENH WRREL
User Enhanced Start: 0 Bytes
User Enhanced Size: 512 MiB
Boot Capacity: 16 MiB ENH
RPMB Capacity: 128 KiB ENH
GP1 Capacity: 64 MiB ENH WRREL
GP2 Capacity: 64 MiB ENH WRREL

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.

mmc: display size and start of eMMC enhanced user data area in mmcinfo

2015-01-19T15:02:29+00:00

This adds output to show the eMMC enhanced user data area size and offset
along with the partition sizes in mmcinfo's output.

mmc: skip mmcinfo partition info processing for eMMC < 4.41

2015-01-19T15:02:21+00:00

eMMC partitions are defined as of eMMC 4.41, but mmcinfo process
partition info for eMMC >= 4.0, change it to do it for >= 4.41

mmc: make eMMC general purpose partition numbering match spec

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

The eMMC spec numbers general purpose partitions starting at 1, but
the mmcinfo output follows the internal numbering which starts at 0.
Make the mmcinfo command output number partitions as in the eMMC
spec to avoid confusion.
