7940a93eb9 net: phy: Iterate over both registered PHYs and struct phy_driver linker list
Introduce U_BOOT_PHY_DRIVER() macro which is used to add struct phy_driver
into a new linker list section containing all compiled in struct phy_driver
drivers. This is so far empty until PHY drivers are converted over to this
macro.

Iterate over both drivers registered using soon to be legacy phy_register()
as well as drivers in the new linker list when looking up a suitable PHY
driver. This way, PHY drivers can be converted over to the new macro one
driver at a time.

The relocation of callbacks for linker list based drivers now happens in
phy_init() call as the drivers are available at that point in time, and
phy_register() is not called for those drivers.

aeb40f1166 tools: env: use /run to store lockfile
According this issue https://github.com/ppp-project/ppp/issues/339.
Eventually, the dt-utils changed lock directory to fix missing /var/lock
directory error then make dt-utils can run normally.

We also have a similar issue with these two utilities fw_printenv and
fw_setenv will failed when the directory /var/lock is non-existent.

We have a custom linux distribution built with yocto (OpenBMC) that
use systemd and it deprecated the /var/lock directory.
More discussion in systemd/systemd#15668.

Thus, we sync with community's solution for uboot/tools/env utilities:
The current location /var/lock is considered legacy (at least by systemd).
Just use /run to store the lockfile and append the usual .lock suffix.

Tested:
Verified /run/lock is now present and fw_printenv can work in OpenBMC.

94c8da2121 lmb: Fix LMB_MEMORY_REGIONS flag usage
Remove test on CONFIG_LMB_MEMORY_REGIONS introduced by commit
7c1860fce4 ("lmb: Fix lmb property's defination under struct lmb").

This code in lmb_init() is strange, because if CONFIG_LMB_USE_MAX_REGIONS
and CONFIG_LMB_MEMORY_REGIONS are not defined, the implicit #else is empty
and the required initialization is not done:
lmb->memory.max = ?
lmb->reserved.max = ?

But this setting is not possible:
- CONFIG_LMB_USE_MAX_REGIONS not defined
- CONFIG_LMB_MEMORY_REGIONS not defined
because CONFIG_LMB_MEMORY_REGIONS and CONFIG_LMB_RESERVED_REGIONS are
defined as soon as the CONFIG_LMB_USE_MAX_REGIONS is not defined.

This patch removes this impossible case #elif and I add some
explanation in lmb.h to explain why in the struct lmb {} the lmb
property is defined if CONFIG_LMB_MEMORY_REGIONS is NOT defined.

This patch also removes CONFIG_LMB_XXX dependency on CONFIG_LMB as these
defines are used in API file lmb.h and not only in library file.

487e42f7bc Merge branch '2023-04-05-blkmap-composable-virtual-block-devices'
To quote the author:
Block maps are a way of looking at various sources of data through the
lens of a regular block device. It lets you treat devices that are not
block devices, like RAM, as if they were. It also lets you export a
slice of an existing block device, which does not have to correspond to
a partition boundary, as a new block device.

This is primarily useful because U-Boot's filesystem drivers only
operate on block devices, so a block map lets you access filesystems
wherever they might be located.

The implementation is loosely modeled on Linux's "Device Mapper"
subsystem, see the kernel documentation [1] for more information.

The primary use-cases are to access filesystem images stored in RAM, and
within FIT images stored on disk. See doc/usage/blkmap.rst for more
details.

The architecture is pluggable, so adding other types of mappings should
be quite easy.

bb56da117f cmd: blkmap: Add blkmap command
Add a frontend for the blkmap subsystem. In addition to the common
block device operations, this allows users to create and destroy
devices, and map in memory and slices of other block devices.

With that we support two primary use-cases:

- Being able to "distro boot" from a RAM disk. I.e., from an image
  where the kernel is stored in /boot of some filesystem supported
  by U-Boot.

- Accessing filesystems not located on exact partition boundaries,
  e.g. when a filesystem image is wrapped in an FIT image and stored
  in a disk partition.

762dc78bde blk: blkmap: Add linear device mapping support
Allow a slice of an existing block device to be mapped to a
blkmap. This means that filesystems that are not stored at exact
partition boundaries can be accessed by remapping a slice of the
existing device to a blkmap device.

c41e209ea6 blk: blkmap: Add basic infrastructure
blkmaps are loosely modeled on Linux's device mapper subsystem. The
basic idea is that you can create virtual block devices whose blocks
can be backed by a plethora of sources that are user configurable.

This change just adds the basic infrastructure for creating and
removing blkmap devices. Subsequent changes will extend this to add
support for actual mappings.
