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.

x86: mmc: Move common FSP functions into a common file

2015-02-06T19:07:36+00:00

Since these board functions seem to be the same for all boards which use
FSP, move them into a common file. We can adjust this later if future FSPs
need more flexibility.

This creates a generic PCI MMC device.

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

mmc: extend the mmc hardware partitioning API with write reliability

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

The eMMC partition write reliability settings are to be set while
partitioning a device, as per the eMMC spec, so changes to these
attributes needs to be done in the hardware partitioning API.
This commit adds such support.

mmc: add API to do eMMC hardware partitioning

2015-01-19T15:41:45+00:00

This adds an API to do hardware partitioning on eMMC devices. The
new mmc_hwpart_config() function does the partitioning in one go.
As the different attributes and partitioning options on eMMC may
be interdependent validation has to be done based on the complete
partitioning configuration. The function accepts three modes:

- MMC_HWPART_CONF_CHECK: just validates that the configuration
  is valid.
- MMC_HWPART_CONF_SET: validates and sets all the fields in
  EXT_CSD but without setting the "partitioning completed" bit,
  and thus is reversible.
- MMC_HWPART_CONF_COMPLETE: does everything and is thus not
  reversible.

mmc: read the high capacity WP group size for eMMC

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

Read the eMMC high capacity write protect group size at mmc device
initialization. This is useful to correctly partition an eMMC device,
as partitions need to be aligned to this size.

mmc: fix erase_grp_size computation with high-capacity size definition

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

The erase_grp_size in struct mmc is to be a size in 512-byte sectors
but the code used to compute it for eMMC when EXT_CSD_ERASE_GROUP_DEF is
enabled computed it as bytes, leading to erase sizes and alignment
much larger than what is actually required by the mmc device.

mmc: read the size of eMMC enhanced user data area

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

This modification reads the size of the eMMC enhanced user data area
upon initialization of an mmc device, it will be used later by
mmcinfo.
