* part:efi: add bootable parameter in gpt commandPatrick Delaunay2015-11-23-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Partition Map for MMC device 0 -- Partition Type: EFI Part Start LBA End LBA Name Attributes 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 devplist=2 Then the distro scripts will search extlinux in partition 2 and not in the first partition.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | short strings can be used in type parameter of gpt command to replace the guid string for the types known by u-boot partitions = name=boot,size=0x6bc00,type=data; \ name=root,size=0x7538ba00,type=linux; gpt write mmc 0 $partitions and they are also used to display the type of partition in "part list" command Partition Map for MMC device 0 -- Partition Type: EFI Part Start LBA End LBA Name Attributes Type GUID Partition GUID 1 0x00000022 0x0000037f "boot" attrs: 0x0000000000000000 type: ebd0a0a2-b9e5-4433-87c0-68b6b72699c7 type: data guid: d117f98e-6f2c-d04b-a5b2-331a19f91cb2 2 0x00000380 0x003a9fdc "root" attrs: 0x0000000000000000 type: 0fc63daf-8483-4772-8e79-3d69d8477de4 type: linux guid: 25718777-d0ad-7443-9e60-02cb591c9737 Signed-off-by: Patrick Delaunay <patrick.delaunay73@gmail.com>

* part:efi: add GUID for linux file system dataPatrick Delaunay2015-11-12-1/+2
| | | | | | | | | | | Previously, Linux used the same GUID for the data partitions as Windows (Basic data partition: EBD0A0A2-B9E5-4433-87C0-68B6B72699C7). This created problems when dual-booting Linux and Windows in UEFI-GPT Setup, so a new GUID (Linux filesystem data: 0FC63DAF-8483-4772-8E79-3D69D8477DE4) was defined jointly by GPT fdisk and GNU Parted developers.

* gpt: support random UUIDs without setting environment variablesRob Herring2015-03-05-3/+5
| | | | | | | | | | Currently, an environment variable must be used to store the randomly generated UUID for each partition. This is not necessary, so make storing the UUID optional. Now passing uuid_disk and uuid are optional when random UUIDs are enabled. Signed-off-by: Rob Herring <robh@kernel.org> Acked-by: Przemyslaw Marczak <p.marczak@samsung.com>
