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.

disk: Provide API to get partition by name for specific type

2017-10-06T15:28:17+00:00

There is already existing function part_get_info_by_name().
But sometimes user is particularly interested in looking for only
specific partition type. This patch implements such an API that
provides partition searching by name for specified partition type.

fs: add fs_readdir()

2017-09-15T13:03:11+00:00

Needed to support efi file protocol.  The fallback.efi loader wants
to be able to read the contents of the /EFI directory to find an OS
to boot.

Modelled after POSIX opendir()/readdir()/closedir().  Unlike the other
fs APIs, this is stateful (ie. state is held in the FS_DIR "directory
stream"), to avoid re-traversing of the directory structure at each
step.  The directory stream must be released with closedir() when it
is no longer needed.

part: efi: make gpt_fill_pte take the device descriptor

The gpt_fill_pte will need to access the device block size. Let's pass the
device descriptor as an argument.

GPT: read partition table from device into a data structure

2017-08-05T00:34:04+00:00

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.

GPT: add accessor function for disk GUID

2017-08-04T13:56:04+00:00

In order to read the GPT, modify the partition name strings, and then
write out a new GPT, the disk GUID is needed.  While there is an
existing accessor for the partition UUIDs, there is none yet for the
disk GUID.

partitions: increase MAX_SEARCH_PARTITIONS and move to part.h

2017-08-04T13:56:03+00:00

Move MAX_SEARCH_PARTITIONS to part.h so that functions in cmd
directory can find it.  At the same time, increase the value to
64 since some operating systems use many, and the resources
consumed by a larger value are minimal.
