Let's introduce the Generic System Interconnect subsystem based on
the counterpart Linux framework which is used to vote for bandwidth
across multiple SoC busses.
Documentation for the Linux Generic System Interconnect Subsystem can
be found at [1].
Each bus endpoints are materialised as "nodes" which are linked together,
and the DT will specify a pair of nodes to enable and set a bandwidth
on the route between those endpoints.
The hardware resources that provide those nodes and provides the way
to vote for the bandwidth are called "providers".
The Interconnect uclass code is heavily based on the Linux one, with
some small differences:
- nodes are allocated as udevices instead of Linux idr_alloc()
- tag management is minimal, only normal xlate is supported
- getting nodes states at probe is not implemented
- providers are probed on demand while the nodes links are traversed
- nodes are populated on bind
- id management is simplified, static IDs and dynamics IDs can be used
- identical consume API as Linux, only implementation differs
Fully tested with associated DM test suite.

This pull request enhances NAND and SPI flash support, primarily
focusing on the Airoha EN7523 platform. The Airoha SPI driver receives
a major update, adding DMA, dual/quad-wire modes, and a critical
workaround to prevent flash damage if the UART_TXD pin shorts to Ground.
New chips supported include FudanMicro FM25S01A SPI-NAND and several
Winbond SPI NOR devices. Fixes include correcting Kconfig dependencies,
updating the mtd benchmark command to use lldiv(), and addressing minor
bugs in the generic spi-mem and SPL NAND code.
When building with clang, we see warnings such as:
error: field max_size within 'struct smbios_type7' is less aligned than
'union cache_size_word' and is usually due to 'struct smbios_type7'
being packed, which can lead to unaligned accesses
[-Werror,-Wunaligned-access]
when building drivers/sysinfo/smbios.c. Resolve this error by packing
the unions as well after verifying they are complete (16 or 32 bits).

Not all ->get_info implementations necessarily populate all the string
members of struct disk_partition.
Currently, only part_get_info_by_type() (and thereby part_get_info)
ensure that the uuid strings are initialized; part_get_info_by_type()
and part_get_info_by_uuid() do not. In fact, the latter could lead to
a false positive match - if the ->get_info backend does not populate
info->uuid, stale contents in info could cause the strncasecmp() to
succeed.
None of the functions currently ensure that the ->name and ->type
strings are initialized.
Instead of forcing all callers of any of these functions to
pre-initialize info, or all implementations of the ->get_info method
to ensure there are valid C strings in all four fields, create a small
helper function and factor all invocations of ->get_info through that.
This also consolidates the -ENOSYS check and standardizes on using
log_debug() for reporting absence, instead of the current mix of
PRINTF and log_debug(). It does mean we have to special-case -ENOSYS
in the error cases inside the loops in the _by_uuid() and _by_name()
functions, but it's still a net win in #LOC.

This patch series adds basic support for the boards based on Airoha
EN7523/EN7529/EN7562 SoCs. Due to ATF restrictions these boards are
able to run 32-bit OS only.
This patch series adds support for the following hardware:
* console UART
* ethernet controller/switch
* spinand flash (in non-dma mode)
The following issues may be expected:
* Extra slow UBI attaching in U-Boot (up to 20 sec with fastmap enabled).
This is caused by the lack of DMA support in the U-Boot airoha-snfi driver.
* Linux airoha-snfi driver in some cases might damage you flash data
(see: https://lore.kernel.org/lkml/20251012121707.2296160-15-mikhail.kshevetskiy@iopsys.eu/)
* Latest linux kernel is recommended to properly support flashes
with more than one plane per lun
(see: https://lore.kernel.org/lkml/20251012121707.2296160-7-mikhail.kshevetskiy@iopsys.eu/)
* It's NOT recommended to use flashes working in continuous mode because
U-Boot airoha-snfi driver does not support such flashes properly.
The patches was tested on the board:
- SoC: Airoha EN7562
- RAM: 512 MB
- SPI NAND: 4 Gbit, made by Toshiba
- Linux boot: was NOT tested
The U-Boot was chain-loaded from the running U-Boot. Airoha ATF-2.3 does
not allow easily chain-loading of U-Boot from U-Boot, so a special FIT
image (mimic linux kernel) was created

Do not over-expose the private dw_mmc API. The glue layer drivers at
this point shouldn't be aware and shouldn't use the generic
dwmci_send_cmd() and dwmci_set_ios() functions. Making those functions
public causes a "leaky abstraction" issue. It clutters the public
interface of generic dw_mmc driver and possibly leads to improper usage
of those functions, so it's a bad design.
If struct dm_dwmci_ops has to be extended, do so by copying it first
(like it's done for example in snps_dw_mmc driver). That also makes sure
the future changes to struct dm_dwmci_ops in dw_mmc driver will be
automatically reflected in all extended copies, and avoid code
duplication.
This effectively reverts commit ef3b16bb8e73 ("mmc: dw_mmc: export
dwmci_send_cmd() and dwmci_set_ios()").
No functional change.

Qualcomm peripherals like UART, SPI, I2C, etc are all exposed under a
common GENI Serial Engine wrapper device. Replace the stub driver we use
for this currently with a full-on misc device and implement support for
loading peripheral firmware.
Each of the peripherals has it's own protocol-specific firmware, this is
stored on the internal storage of the device with a well-known partition
type GUID.
To support this, GENI will bind peripherals in two stages. First the
ones that already have firmware loaded (such as the serial port) are
bound in the typical way. But devices that require firmware loading are
deferred until EVT_LAST_STAGE_INIT. At this point we can be sure that
the storage device is available, so we load the firmware and then bind
and probe the remaining children.
Child devices are expected to determine if firmware loading is necessary
and call qcom_geni_load_firmware().
Since Linux currently doesn't support loading firmware (and firmware may
not be available), we probe all GENI peripherals to ensure that they
always load firmware if necessary.

Some boards have SD card connectors where the power rail cannot be switched
off by the driver. However there are various circumstances when a card
might be re-initialized, such as after system resume, warm re-boot, or
error handling. However, a UHS card will continue to use 1.8V signaling
unless it is power cycled.
If the card has not been power cycled, it may still be using 1.8V
signaling. According to the SD spec., the Bus Speed Mode (function group 1)
bits 2 to 4 are zero if the card is initialized at 3.3V signal level. Thus
they can be used to determine if the card has already switched to 1.8V
signaling. Detect that situation and try to initialize a UHS-I (1.8V)

In the Linux kernel driver, all information related to LDO and BUCK
regulators are stored in descriptive arrays. This also allows multiple
variants to be supported by the same driver.
Define a struct sec_regulator_desc which holds all values required by a
regulator. Create an array of said struct containing all regulators. The
descriptors are designed to follow a style similar to what's seen in the
Linux driver, so comparing one with the other is simple.
In functions such as s2mps11_{buck,ldo}_{val,mode} these values are to
be used, make necessary modifications to pull them from the descriptors.
Since multiple variants have varying descriptors, select them from
within a switch-case block.
Functions s2mps11_{buck,ldo}_{volt2hex,hex2volt} and arrays
s2mps11_buck_{ctrl,out} are phased out as the calculations are now
hardcoded in descriptors, thusly, it reduces clutter and enhances

During a voltage switch command (CMD11, opcode: SD_CMD_SWITCH_UHS18V),
certain hosts tend to stop responding to subsequent commands. This is
addressed by introducing an additional command flag,
DWMCI_CMD_VOLT_SWITCH.
The associated interrupt bit is defined as DWMCI_INTMSK_VOLTSW. This is
set high when a voltage switch is issued, this needs to be waited for
and set to low. Implement the same in the timeout loop. Do note that
since DWMCI_INTMSK_VOLTSW shares the same bit as DWMCI_INTMSK_HTO (bit
10), the interrupt bit needs to be polled for only if the volt switch
command is issued.
DWMCI_CMD_VOLT_SWITCH also needs to be set for subsequent clken commands
after the volt switch. To ensure this, add a boolean member in the host
private struct (herein named volt_switching), which informs if the last
command issued was for volt switching or not.
