No functional changes, just some refactoring to better match linux
kernel driver.
changes:
* move spinand configuration reading out from spinand_init_cfg_cache()
to separate function spinand_read_cfg()
* move spinand flash initialization to separate function
spinand_init_flash()
* move direct mapping initialization to the end of spinand_init()

This aligns spinand_wait() with the linux kernel. Instead of calling into
spi_mem_poll_status() which is not implemented in U-Boot, we code the

SoCFPGA updates for v2025.10:
CI: https://source.denx.de/u-boot/custodians/u-boot-socfpga/-/pipelines/27762
This pull request brings a set of updates across SoCFPGA platforms
covering Agilex5, Agilex7, N5X, and Stratix10. The changes include:
* Agilex5 enhancements:
- USB3.1 enablement and DWC3 host driver support
- System Manager register configuration for USB3
- Watchdog timeout increase and SDMMC clock API integration
- dcache handling improvements in SMC mailbox path
- Enable SPL_SYS_DCACHE_OFF in defconfig
* Clock driver improvements:
- Introduce dt-bindings header for Agilex clocks
- Add enable/disable API and EMAC clock selection fixes
- Replace manual shifts with FIELD_GET usage
* DDR updates:
- IOSSM mailbox compatibility check
- Correct DDR calibration status handling
* Device tree changes:
- Agilex5: disable cache allocation for reads
- Stratix10: add NAND IP node
- Enable driver model watchdog
- Enable USB3.1 node for Agilex5
* Config cleanups:
- Simplify Agilex7 VAB defconfig
- Remove obsolete SYS_BOOTM_LEN from N5X VAB config
- Enable CRC32 support for SoCFPGA
- Increase USB hub debounce timeout
Overall this set improves reliability of DDR and cache flows,
adds missing USB and MMC features for Agilex5, and refines clock
and configuration handling across platforms.
This patch set has been tested on Agilex 5 devkit, and Agilex devkit.

In meson_pwm_probe the for loop attempts to get the name of a clock but
the following if..else statements only perform useful work if -ENODATA
is returned from clk_get_by_name. If clk_get_by_name simply succeeds
then this results in a premature exit from the for loop and the
following code can never be reached. Make the else clause only apply for
an error return from clk_get_by_name.

This bit is necessary to receive packets from the internal PHY.
Without this bit set, no activity occurs on the interface.
Normally u-boot sets this bit, but if u-boot is compiled without
net support, the interface will be up but without any activity.
The vendor SDK sets this bit along with the PHY_ID bits.

The issue was a mismatch in return value conventions between functions:
- getvar_get_part_info() expects >= 0 for success
- fb_nand_lookup() returns 0 on success, 1 on failure (from
mtdparts_init and find_dev_and_part)
When partition didn't exist, fb_nand_lookup returned 1, but
fastboot_nand_get_part_info passed it directly to getvar_get_part_info,
which treated 1 >= 0 as success, causing has-slot to always return yes.
Fix by converting positive return values to -ENOENT in
fastboot_nand_get_part_info to match the expected error convention.

According to i.MX8DXL A1 errata ERR050601, concurrent read accesses
from the A35 cores to the peripherals within the LSIO subsystem
(region 0_5DXX_XXXX) and address spaces in the regions
[0_0000_0000 – 0_1BFF_FFFF] and [4_0000_0000 – 4_3FFF_FFFF] can collide
and cause data corruption in the returned data, with no failure report.
Even a single A35 core accessing both these regions can trigger the issue
because an A35 core can have more than one parallel read operation in
progress.
The flexspi0 AHB memory is in LSIO region mentioned in above errata.
So we can't use AHB read, only can read data from FIFO.
Add the compatible string for 8DXL and use a flag for the IPS read.

R-Car V4H Reference Manual R19UH0186EJ0130 Rev.1.30 Apr. 21, 2025 page 585
Figure 9.3.2 Software Reset flow (B) indicates that for peripherals in HSC
domain, after reset has been asserted by writing a matching reset bit into
register SRCR, it is mandatory to wait 1ms.
Because it is the controller driver which can determine whether or not the
controller is in HSC domain based on its compatible string, add the missing
delay into the controller driver.
This 1ms delay is documented on R-Car V4H and V4M, it is currently unclear
whether S4 is affected as well. This patch does apply the extra delay on
R-Car S4 as well.

Assure the reset is latched and the core is ready for DBI access.
On R-Car V4H, the PCIe reset is asynchronized and does not take
effect immediately, but needs a short time to complete. In case
DBI access happens in that short time, that access generates an
SError. Make sure that condition can never happen, read back the
state of the reset which should turn the asynchronized reset into
synchronized one, and wait a little over 1ms to add additional
safety margin.

R-Car V4H Reference Manual R19UH0186EJ0130 Rev.1.30 Apr. 21, 2025 page 4581
Figure 104.3b Initial Setting of PCIEC(example), third quarter of the figure
indicates that register 0xf8 should be polled until bit 18 becomes set to 1.
Register 0xf8 bit 18 is 0 immediately after write to PCIERSTCTRL1 and is set
to 1 in less than 1 ms afterward. The current readl_poll_timeout() break
condition is inverted and returns when register 0xf8 bit 18 is set to 0,
which in most cases means immediately. In case CONFIG_DEBUG_LOCK_ALLOC=y ,
the timing changes just enough for the first readl_poll_timeout() poll to
already read register 0xf8 bit 18 as 1 and afterward never read register
0xf8 bit 18 as 0, which leads to timeout and failure to start the PCIe
controller.
Fix this by inverting the poll condition to match the reference manual
initialization sequence.
