Replace hardcoded WDOG_BASE_ADDR with driver model based dynamic address
lookup from device tree, allowing reset_cpu() to dynamically locate
watchdog devices from device tree.
This change also enables CONFIG_WDT for relevant boards and ensures the
watchdog nodes are available for driver model usage.
- Remove hardcoded WDOG_BASE_ADDR from hw_watchdog_* functions
- Reimplement reset_cpu() using UCLASS_WDT device iteration
- Add ulp_wdt_expire_now() callback for standard WDT interface
- Pass wdog register pointer to hw_watchdog_set_timeout()
- Enable CONFIG_WDT for boards using ULP watchdog
- Remove wdog3 status = "disabled" overrides from U-Boot device tree
overlays, as the watchdog device needs to be accessible for driver
model based reset functionality.

- eth, phy: Convert several drivers to use the dev APIs
- Guard SYS_RX_ETH_BUFFER with NET
- phy: Kconfig: use bool instead of tristate
Convert mvpp2 driver from legacy fdtdec/fdt_* APIs to the ofnode-based
interfaces.
Replace usage of dev_of_offset(), fdtdec_lookup_phandle(),
fdtdec_get_int(), fdt_parent_offset(), and related helpers with their
ofnode equivalents, including dev_ofnode(), ofnode_parse_phandle(),
ofnode_read_s32_default(), ofnode_get_parent(), and
ofnode_for_each_subnode().
Remove direct dependencies on gd->fdt_blob.
Main changes:
- Use ofnode_valid() instead of integer checks for node presence
- Switch fixed-link detection to ofnode_find_subnode()
- Replace uclass_get_device_by_of_offset() with
uclass_get_device_by_ofnode()
- Update subnode iteration and device binding to use ofnode

Replace legacy FDT parsing in get_reg() with the device API
dev_read_phandle_with_args() which removes direct access to gd->fdt_blob
and aligns the driver with modern U-Boot DT handling.
The offset is retrieved from the phandle argument instead of manually
parsing the property cells. Add validation for the argument
count to avoid out-of-bounds access on malformed DTs.
Also switch from devfdt_get_addr_size_index() to dev_read_addr_size_index()
for consistency with the DM API.

Tom Rini <trini@konsulko.com> says:
This series does a few small but important cleanups to how we check for,
and initialize a bloblist. The first thing is that the way things are
done today, our HANDOFF code can only work with a fixed bloblist
location, so express that requirement in Kconfig. Next, we demote the
scary message about "Bloblist at ... not found" to a debug because we
most often see that because the bloblist doesn't (and can't) exist yet.
Finally, we remove bloblist_maybe_init and split this in to an exists
and a real init. This results in practically no growth (between 8 bytes
growth to 12 bytes saved, with some outliers saving much more thanks to
knowing it's impossible to have been passed a bloblist yet). This also
cleans up some of the code around checking for / knowing about a
bloblist existing.

Sync include/ec_commands.h from upstream commit 4f3d17aa34
("skywalker: set SLEEP_TIMEOUT_MS to 50 seconds"). The new file makes
two build assumptions that do not hold for U-Boot.
It hides '<stdint.h>' from __KERNEL__ builds, leaving UINT16_MAX
(used by EC_RES_MAX) undefined for U-Boot; widen the gate to
'!defined(__KERNEL__) || defined(__UBOOT__)'
It gates '<linux/limits.h>' on '#ifdef __KERNEL__'; the matching
'#else' branch defines BIT()/BIT_ULL()/GENMASK()/GENMASK_ULL()
locally, assuming kernel headers provide those macros otherwise.
U-Boot defines __KERNEL__ too but has no <linux/limits.h>. Nest a
'!defined(__UBOOT__)' check around the include so the __UBOOT__ path
stays in the __KERNEL__ branch (no local BIT/GENMASK defines), which
avoids redefinition warnings against U-Boot's linux/bitops.h. Pull
in linux/bitops.h up front for U-Boot so the file's own BIT() and
GENMASK() uses still resolve.
Adapt callers to two interface changes. The 'ec_current_image' enum
tag is now 'ec_image' (EC_IMAGE_* constants unchanged); rename it in
affected files to match. The VBNV-context interface was dropped
upstream, but it still used in lab Chromebooks; keep those constants and
structs in cros_ec.h
Likewise, MEC_EMI_BASE and MEC_EMI_SIZE are a U-Boot-local addition to
ec_commands.h that the upstream sync removes; preserve them in cros_ec.h
next to the VBNV block, and switch the only consumer
(arch/x86/cpu/apollolake/cpu_spl.c) to include cros_ec.h

When fpga load is called with a misaligned buffer address, the
versal_align_dma_buffer() function shifts the pointer forward to the
next aligned boundary and uses memcpy() to copy the data. Since the
destination is ahead of the source and the regions overlap, memcpy()
produces undefined behavior; in practice U-Boot's generic memcpy()
copies forward, repeating the first ARCH_DMA_MINALIGN-aligned chunk
throughout the buffer.
Replace memcpy() with memmove() which correctly handles overlapping
regions by copying backwards when the destination is ahead of the
source.

Currently we are trying to work out if the vendor id is from
a virtio-mmio device and then casting a u32 to a char* and using
it as a C-string. By chance there is usually a zero after the u32
and it works.
Since the vendor id we are trying to convert to a string is QEMU's
just define a value for the QEMU vendor id, check if the vendor
id matches and then use a predefined string for "QEMU".
I don't think we should have been assumming all virtio-mmio vendor
ids are printable ASCII chars in the first place so do this special
casing just for QEMU. If the vendor id isn't QEMU print the hex
value of it.
