LDR format files are used primarily by Analog Devices processors but may
be of interest to other vendors. Previously support existed for this
format as part of the U-Boot build, but it has been unmaintained and
unused for a long time. In preparation for adding support for modern ADI
processors that use LDR, modernize the LDR support:
- Introduce CONFIG_LDR_CPU as the CPU string recognized by the LDR tool
may not be the same as CONFIG_CPU
- Add an SPL target that repackages u-boot-spl inside an LDR file
An almost identical target for packaging u-boot into an LDR file already
exists and did not need to be created.

arm64: Fix map_range() not splitting mapped blocks
The implementation of map_range() creates the requested mapping by
walking the page tables, iterating over multiple PTEs and/or descending
into existing table mappings as needed. When doing so, it assumes any
pre-existing valid PTE to be a table mapping. This assumption is wrong
if the platform code attempts to successively map two overlapping ranges
where the latter intersects a block mapping created for the former.
As a result, map_range() treats the existing block mapping as a table
mapping and descends into it i.e. starts interpreting the
previously-mapped range as an array of PTEs, writing to them and
potentially even descending further (extra fun with MMIO ranges!).
Instead, pass any valid non-table mapping to split_block(), which
ensures that it actually was a block mapping (calls panic() otherwise)
before splitting it.

riscv: support extension probing using riscv, isa-extensions
A new property has been added, with an extensive rationale at [1], that
can be used in place of "riscv,isa" to indicate what extensions are
supported by a given platform that is a list of strings rather than a
single string. There are some differences between the new property,
"riscv,isa-extensions" and the incumbent "riscv,isa" - chief among them
for the sake of parsing being the list of strings, as opposed to a
string. Another advantage is strictly defined meanings for each string
in a dt-binding, rather than deriving meaning from RVI standards. This
will likely to some divergence over time, but U-Boot's current use of
extension detection is very limited - there are just four callsites of
supports_extension() in mainline U-Boot.
These checks are limited to two checks for FPU support and two checks
for "s" and "u". "s" and "u" are not supported by the new property, but
they were also not permitted in "riscv,isa". These checks are only
meaningful (or run) in M-Mode, in which case supports_extension() does
not parse the devicetree anyway.
Add support for the new property in U-Boot, prioritising it, before
falling back to the, now deprecated, "riscv,isa" property if it is not
present.

riscv: don't read riscv, isa in the riscv cpu's get_desc()
cpu_get_desc() for the RISC-V CPU currently reads "riscv,isa" to get
the description, but it is no longer a required property and cannot be
assummed to always be present, as the new "riscv,isa-extensions" and
"riscv,isa-base" properties may be present instead.
On RISC-V, cpu_get_desc() has two main uses - firstly providing an
informational name for the CPU for smbios or at boot with
DISPLAY_CPUINFO etc and secondly it forms the basis of ISA extension
detection in supports_extension() as it returns (a portion of) an ISA
string.
cpu_get_desc() returns a string, which aligned with "riscv,isa" but
the new property is a list of strings. Rather than add support for
the list of strings property, which would require creating an isa
string from "riscv,isa-extensions", modify the RISC-V CPU's
implementaion of cpu_get_desc() return the first compatible as the
cpu description instead. This may be fine for the informational cases,
but it would break extension dtection, given supports_extension()
expects cpu_get_desc() to return an ISA string.
Call dev_read_string() directly in supports_extension() to get the
contents of "riscv,isa" so that extension detection remains functional.
As a knock-on affect of this change, extension detection is no longer
broken for long ISA strings. Previously if the ISA string exceeded the
32 element array that supports_extension() passed to cpu_get_desc(),
it would return ENOSPC and no extensions would be detected.
This bug probably had no impact as U-Boot does not currently do anything
meaningful with the results of supports_extension() and most SoCs
supported by U-Boot don't have anywhere near that complex of an ISA
string. The QEMU virt machine's CPUs do however, so extension detection
doesn't work there.

always-on so that it will be enabled automatically during boot.

get_function_mux() callback needs to know for which pin the function

arm: mvebu: turris_omnia: Implement getting board information from MCU
Implement reading board serial number, first MAC address and board
version from MCU. MCU supports board information if the FEAT_BOARD_INFO
feature bit is set in MCU features.
Prefer getting board information from MCU if supported, fallback to
Atmel SHA chip.

arm: mvebu: turris_omnia: Update MCU status and features reading
Refactor MCU status word and MCU firmware features reading to make it
simpler to use.
Try reading 32 bits of features, if that fails, read 16 bits. Older MCU
firmware supports only 16-bit wide features, and if more bytes are read,
either 0xff is sent or I2C transaction fails. Handle both cases.
