      board: at91sam9261ek: Update to support DT and DM · 324873e7
      Wenyou.Yang@microchip.com authored 
      
Add the dts files to support deivce tree, update the configuration
files to support the device tree and driver model. The peripheral
clock and pins configuration are handled by the clock and the pinctrl
drivers respectively.

Enable the early debug UART to debug problems when an ICE or other
debug mechanism is not available.

      gpt: harden set_gpt_info() against non NULL-terminated strings · 2fcaa413
      Alison Chaiken authored 
      
Strings read from devices may sometimes fail to be
NULL-terminated.   The functions in lib/string.c are subject to
failure in this case.   Protect against observed failures in
set_gpt_info() by switching to length-checking variants with a length
limit of the maximum possible partition table length.  At the same
time, add a few checks for NULL string pointers.

Here is an example as observed in sandbox under GDB:

    => gpt verify host 0 $partitions
    Program received signal SIGSEGV, Segmentation fault.
    0x0000000000477747 in strlen (s=0x0) at lib/string.c:267

      GPT: provide commands to selectively rename partitions · 203f9b48
      Alison Chaiken authored 
      
This patch provides support in u-boot for renaming GPT
partitions.  The renaming is accomplished via new 'gpt swap'
and 'gpt rename' commands.

The 'swap' mode returns an error if no matching partition names
are found, or if the number of partitions with one name does not equal
the number with the second name.   The 'rename' variant always
succeeds as long as a partition with the provided number exists.

Rewriting the partition table has the side-effect that all partitions
end up with "msftdata" flag set.  The reason is that partition type
PARTITION_BASIC_DATA_GUID is hard-coded in the gpt_fill_pte()
function.  This does not appear to cause any harm.

      GPT: read partition table from device into a data structure · 09a49930
      Alison Chaiken authored 
      
Make the partition table available for modification by reading it from
the user-specified device into a linked list.   Provide an accessor
function for command-line testing.
