cmd: part: Add subcommand to list supported partition tables

2020-07-07T19:22:42+00:00

Add a subcommand "types" to the part command, which lists the supported
partition table types.

command: Remove the cmd_tbl_t typedef

2020-05-18T22:36:55+00:00

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.

part: Drop disk_partition_t typedef

2020-05-18T21:33:33+00:00

We should not be using typedefs and these make it harder to use
forward declarations (to reduce header file inclusions). Drop the typedef.

cmd: part: number: return hexadecimal value

2019-10-04T16:21:23+00:00

At this point we are using part number sub-command to retrieve UUID
of the partition using it's name.

e.g.:
 part number mmc $mmcdev system_a system_a_index
 part uuid mmc $mmcdev:${system_a_index} system_a_uuid

Since 'part uuid' sub-command expects partition index in hex format and
'part number' returns decimal value, 'part uuid' command will provide
wrong UUID or fail.

cmd: part: Add 'number' sub-command

2019-07-24T17:16:29+00:00

This sub-command serves for getting the partition index from
partition name. Also it can be used to test the existence of specified
partition.

Use case:
For example, in most CI environments this U-Boot command for automatic
testing of Linux rootfs is used:

    => setenv bootpart 1:f

where 0xf is "userdata" partition. But the number of "userdata"
partition can be changed any time, when partition table is changed.

So it would be nice to get rid of that 0xf magic number and use
partition name instead, like this:

    => part number mmc 1 userdata part_num
    => setenv bootpart 1:${part_num}

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

cmd: part: Allow passing partition name to start and size

2018-03-14T01:59:26+00:00

Allow passing the partition name to "part start" and "part size"
commands, so we can avoid magic numbers in the environment.

Consider one real use-case: in include/environment/ti/boot.h we have
commands like these:

    setenv boot_part 9
    part start mmc ${mmcdev} ${boot_part} boot_start
    part size mmc ${mmcdev} ${boot_part} boot_size
    mmc read ${loadaddr} ${boot_start} ${boot_size}

Now suppose that we have changed the partition table and boot_part now
is 10. We will need to fix commands above. And anyone who relies on
these boot commands, will need to change them accordingly, too (this was
an actual case in our lab while testing Linux boot on Android
environment).

By providing the option to pass partition name instead, we fix mentioned
issue, by eliminating the necessity to use magic numbers.
