Patrick Delaunay cfdaf4caa2 part:efi: add bootable parameter in gpt command
The optional parameter bootable is added in gpt command to set the
partition attribute flag "Legacy BIOS bootable"

This flag is used in extlinux and so in with distro to select
the boot partition where is located the configuration file
(please check out doc/README.distro for details).

With this parameter, U-Boot can be used to create the boot partition
needed for device using distro.

example of use:

setenv partitions "name=u-boot,size=60MiB;name=boot,size=60Mib,bootable;\
                   name=rootfs,size=0"

> gpt write mmc 0 $partitions

> part list mmc 0

> part list mmc 0 -bootable devplist

> printenv devplist

devplist=2

Then the distro scripts will search extlinux in partition 2
and not in the first partition.
