7633903bff Blackfin: allow serial console to be disabled
Some devices have no UART device pulled out, so allow people to disable the
driver completely in favor of other methods (like JTAG-console).

be853bf86b Blackfin: overhaul i2c driver
The current Blackfin i2c driver does not work properly with certain devices
due to it breaking up transfers incorrectly.  This is a rewrite of the
driver and relocates it to the newer place in the source tree.

Also remove duplicated I2C speed defines in Blackfin board configs and
disable I2C slave address usage since it isn't implemented.

cf7e399fb3 SATA: do not auto-initialize during boot
Rather than have the board code initialize SATA automatically during boot,
make the user manually run "sata init".  This brings the SATA subsystem in
line with common U-Boot policy.

Rather than having a dedicated weak function "is_sata_supported", people
can override sata_initialize() to do their weird board stuff.  Then they
can call the actual __sata_initialize().

5097083971 part_efi: Fix partition size calculation due to inclusive ending LBA.
The ending LBA is inclusive. Hence, the partition size should be
((ending-LBA + 1) - starting-LBA) to get the proper partition size.

This is confirmed against the results from the parted tool.
(e.g. use parted /dev/sda -s unit S print) and observe the size.

b5b004ad8a jffs2: Fix zero sector_size when not using CONFIG_JFFS2_CMDLINE
This patch fixes a bug (?) introduced after inclusion of the new
JFFS2 code.

When not using CONFIG_JFFS2_CMDLINE, the code in cmd_jffs2.c doesn't
fill in part->sector_size (keeping it as 0), but a correct value is
needed by the code in jffs2_1pass.c. This causes all JFFS2 accesses
to be in the same place of the memory, what obviously means
impossibility to use the JFFS2 partition.

This problem is fixed in this patch by including sector size
calculation in non-CONFIG_JFFS2_CMDLINE mtdparts_init variant.

2ac6985a74 soft_i2c.c add option for repeated start in i2c_read()
This patch adds a #define to optionally change the behaviour of
i2c_read() in soft_i2c.c to send an I2C repeated start instead of a
stop-start between sending the device address pointer write and
reading back the data.  The current behaviour is retained as the
default.

While most devices will work either way, I have a smart battery(*)
that requires repeated start, and someone at some point found a
device that required a stop-start.
