    part:efi: add bootable parameter in gpt command · cfdaf4ca
    Patrick Delaunay authored
    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;\
    > gpt write mmc 0 $partitions
    > part list mmc 0
    Partition Map for MMC device 0  --   Partition Type: EFI
    Part	Start LBA	End LBA		Name
    	Type GUID
    	Partition GUID
      1	0x00000022	0x0001e021	"u-boot"
    	attrs:	0x0000000000000000
    	type:	ebd0a0a2-b9e5-4433-87c0-68b6b72699c7
    	guid:	cceb0b18-39cb-d547-9db7-03b405fa77d4
      2	0x0001e022	0x0003c021	"boot"
    	attrs:	0x0000000000000004
    	type:	ebd0a0a2-b9e5-4433-87c0-68b6b72699c7
    	guid:	d4981a2b-0478-544e-9607-7fd3c651068d
      3	0x0003c022	0x003a9fde	"rootfs"
    	attrs:	0x0000000000000000
    	type:	ebd0a0a2-b9e5-4433-87c0-68b6b72699c7
    	guid:	6d6c9a36-e919-264d-a9ee-bd00379686c7
    > part list mmc 0 -bootable devplist
    > printenv devplist
    Then the distro scripts will search extlinux in partition 2
    and not in the first partition.
