37bb396669 timer: orion-timer: Only init timer once
Move the code making sure that the timer is initialized only once into
orion_timer_init(), which is called from timer_early_init() and from
orion_timer_probe(). This way the timer is not re-initialized.

1ba0018218 mtd: nand: pxa3xx: simplify ECC hardware parameters
Replace the if/else chain in pxa_ecc_init() with a lookup table. This
makes the code more concise and hopefully easier to follow. Remove the
unused ecc_layout tables and replace it with a single dummy one (the
pxa3xx driver has never used this but the mtd subsystem expects it to be
provided).

aba0e6510f mmc: zynq_sdhci: Read power-domains id from DT and use
Firmware calls need node_id which is basically "power-domains" id.
At present static values are used based on the "device_id" property of
dt.
Instead of this, read "power-domains" id from dt and use it. Add a
element called node_id in priv structure and read it from dt. Replace
static node_id with this priv->node_id across the driver.

Since "device_id" is not used anywhere else simply remove it.

078d8eb5bb net: emaclite: enable for more architectures
Function ioremap_nocache seems to be defined only for MIPS and Microblaze
architectures. Therefore, the function call in the emaclite driver causes
this driver to be unusable with other architectures, for example RISC-V.

Use ioremap function instead of ioremap_nocache, and include linux/io.h
instead of asm/io.h, so that ioremap function is automatically created,
if not defined by the architecture. We can switch to the ioremap function,
as Microblaze's ioremap_nocache is just empty and in MIPS implementations
of ioremap_nocache and ioremap are the same.

constantly reboot.  Fix this by adding the spba node to the spl
device tree to restore normal booting.

6ee6e15975 Merge branch '2022-09-29-dm-core-support-multiple-device-trees-in-ofnode' into next
To quote the author:
At present the ofnode interface is somewhat limited, in that it cannot
access the device tree provided by the OS, only the one used by U-Boot
itself (assuming these are separate). This prevents using ofnode functions
to handle device tree fixups, i.e. ft_board_setup() and the like.

The ofnode interface was introduced to allow a consistent API to access
the device tree, whether a flat tree or a live tree (OF_LIVE) is in use.

With the flat tree, adding nodes and properties at the start of the tree
(as often happens when writing to the /chosen node) requires copying a
lot of data for each operation. With live tree, such operations are
quite a bit faster, since there is no memory copying required. This has to
be weighed against the required memory allocation with OF_LIVE, as well
as the cost of unflattening and flattening the device tree which U-Boot
is running.

This series enables support for access to multiple device trees with the
ofnode interface. This is already available to some extent with OF_LIVE,
but some of the ofnode functions need changes to allow the tree to be
specified.

The mechanism works by using the top 1-4 bits of the device tree offset.
The sign bit is not affected, since negative values must be supported.

With this implemented, it becomes possible to use the ofnode interface
to do device tree fixups. The only current user is the EVT_FT_FIXUP
event.

This has two main benefits:

- ofnode can now be used everywhere, in preference to the libfdt calls
- live tree can eventually be used everywhere, with potential speed
  improvements when larger number of fixups are used

This series is only a step along the way. Firstly, while it is possible
to access the 'fix-up' tree using OF_LIVE, most of the fixup functions use
flat tree directly, rather than the ofnode interface. These need to be
updated. Also the tree must be flattened again before it is passed to the
OS. This is not currently implemented.

With OFNODE_MULTI_TREE disabled this has almost no effect on code size:
around 4 bytes if EVENT is enabled, 0 if not. With the feature enabled,
the increase is around 700 bytes, e.g. on venice2:

$ buildman -b ofn2a venice2 -sS --step 0
Summary of 2 commits for 1 boards (1 thread, 64 jobs per thread)
01: image: Drop some other #ifdefs in image-board.c
       arm:  w+   venice2
48: wip
       arm: (for 1/1 boards) all +668.0 text +668.0

This size increase is not too bad, considering the extra functionality,
but is too large to enable everywhere. So for now this features needs to
be opt-in only, based on EVENT.

0b58eaa89c dm: core: Allow copying ofnode property data when writing
At present ofnode_write_prop() is inconsistent between livetree and
flattree, in that livetree requires the caller to ensure the property
value is stable (e.g. in rodata or allocated) but flattree does not, since
it makes a copy.

This makes the API call a bit painful to use, since the caller must do
different things depending on OF_LIVE.

Add a new 'copy' argument which tells the function to make a copy if
needed. Add some tests to cover this behaviour.

92291652b5 dm: core: Add the ofnode multi-tree implementation
Add the logic to redirect requests for the device tree through a function
which can look up the tree ID. This works by using the top bits of
ofnode.of_offset to encode a tree.

It is assumed that there will only be a few device trees used at runtime,
typically the control FDT (always tree ID 0) and possibly a separate FDT
to be passed the OS.

The maximum number of device trees supported at runtime is 8, with this
implementation. That would use bits 30:28 of the node-offset value,
meaning that the positive offset range is limited to bits 27:0, versus
30:1 with this feature disabled. That still allows a device tree of up
to 256MB, which should be enough for most FITs. Larger ones can be
supported by using external data with the FIT, or by enabling OF_LIVE.

Update the documentation a little and fix up the comment for
ofnode_valid().

41b65d68ec dm: core: Add definitions for multiple ofnode trees
At present, unless OF_LIVE is enabled, ofnode only supports access to one
device tree, the control FDT. This is because only the node offset is
encoded in ofnode, with the tree being implicit.

This makes ofnode (without OF_LIVE) unsuitable for device tree fixups, as
implemented by ft_board_setup() and other such functions.

To solve this, we can use the top bits of the node offset to hold a tree
ID.

Add the definitions for this.

ee88ba71ac dm: core: Provide a way to reset the device tree
At present there is only one device tree used by the ofnode functions,
except for some esoteric use of live tree. In preparation for supporting
more than one, add a way to reset the list of device trees.

For now this does nothing.

66d0d0c188 dm: core: Expand integer-reading tests
The current tests do not cover all the behaviour. Add some more.

Tidy up a few inconsistencies between livetree and flattree which come to
light with these tests. Also drop the -ENODATA error since it is never
actually returned.

0dfc4c84d8 efi_selftest: prefix test functions with efi_st_
An upcoming patch set creates a global function flush(). To make debugging
easier we should not use the same name for a static function.

Rename static functions in the LoadImage() unit test adding an efi_st_
prefix.

0e21943b94 doc: improve description of autostart
Complete the list of commands influenced by the autostart environment
variable.

Make it clearer what values qualifies at 'yes'.

Eventually the list of environment variables is to be alphabetically
sorted. Move autostart up.

f46ec93ed5 dm: core: Avoid creating a name property when unflattening
The current implementation creates a 'name' value for every node. This
is not needed for the latest device tree format, which includes a name in
the node header.

Adjust the code to point the name at the node header instead.

Also simplify ofnode_get_name(), now that we can rely on it to set the
name correctly. Update the comment to make it clear what name the root
node has.

8d468a188f sandbox: test: Provide an easy way to use the other FDT
Add a test flag which indicates that the 'other' FDT should be set up
ready for use. Handle this by copying in the FDT, unflattening it for
livetree tests. Free the structures when the tests have run.

We cannot use the other FDT unless we are using live tree or
OFNODE_MULTI_TREE is enabled, since only one tree is supported by the
ofnode interface in that case. Add this condition into
ut_run_test_live_flat() and update the comments.
