5002d8cc54 MIPS: bootm: prepare a flattened device tree for the kernel
Add the initial code to prepare a flattened device tree for
the kernel like relocating the FDT blob and fixing up the
/chosen and /memory nodes.

The final hand over to the kernel is not yet implemented. After
the community agreed on the MIPS boot interface for device trees,
the corresponding code will be added.

fc5b32fbf3 mmc: Skip changing bus width for MMC cards earlier than version 4.0
Wider bus widths (larger than default 1 bit) appeared in MMC standard
version 4.0. So, for MMC cards of any earlier version trying to change
the bus width (including ext_csd comparison) does not make any sense.
It may work incorrectly and at least cause unnecessary timeouts.
So, just skip the entire bus width related activity for earlier versions.

bf4770731c mmc: Avoid redundant switching to 1-bit bus width for MMC cards
If all the commands switching an MMC card to 4- or 8-bit bus width fail,
and the bus width for the controller and the driver is still set
to default 1 bit, there is no need to send one more command to switch
the card to 1-bit bus width. Also, if the card or host controller do not
support wider bus widths, there is no need to send a switch command at all.

However, if one of switch commands succeeds, but the subsequent ext_csd
fields comparison fails, the card should be switched to some other bus width
(next in the list for the loop), or to default 1-bit bus width as a last
resort. That's why it would be incorrect to just remove the 1-bit bus width
case from the list, it should still be processed in some cases.

ac9da0e08c mmc: add API to do eMMC hardware partitioning
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.

bc897b1d4d. We now bail out if

8a0cf49010 mmc: eMMC partitioning data is not effective till partitioning completed
The eMMC spec says that partitioning is only effective after the
PARTITION_SETTING_COMPLETED is set in EXT_CSD (and a power cycle was done,
but that we cannot know). Thus the partition sizes and attributes should
be ignored when that bit is not set, otherwise the various capacities
are not coherent (e.g., the user data capacity will be that of the
unpartitioned device while partition sizes would be non-zero).

Prescence of non-zero partitioning data is nevertheless still used to
activate the high-capacity size definitions (EXT_CSD_ERASE_GROUP_DEF)
as it is necessary to set that to write any of the partitioning fields
in EXT_CSD, so having partitioning data means someone previously
activated that and we should keep it activated.

0c453bb76c mmc: incomplete test to switch to high-capacity group size definitions
The eMMC spec mandates that the high-capacity group size definitions
should be enabled when the device is partitioned (by setting
ERASE_GROUP_DEF in EXT_CSD). The current test to determine when this is
required misses a few cases. In particular a device may have been
partitioned without setting the enhanced attribute on any partition
or partitioning may be completed without creating any extra partitions.

This change moves the code to set ERASE_GROUP_DEF to after reading
all partition information. It is also enabled when
PARTITIONING_SETTING_COMPLETED is set as it is necessary to enable
ERASE_GROUP_DEF before setting that bit, so it means that the user
previously switched to the high capacity definitions.
