Add reset_reset() and reset_reset_bulk() functions to the reset
controller API. These functions assert and then deassert reset signals
in a single call, providing a convenient way to pulse/toggle a reset
line.
This mimics the Linux kernel's reset_control_reset() and
reset_control_bulk_reset() APIs. The new functions are useful for
drivers that need to cycle a reset line during initialization or
error recovery but with also passing delay parameter.
If a driver implements the rst_reset op, it will be called directly
with the delay parameter. Otherwise, the reset core performs
reset_assert(), optional udelay(), and reset_deassert() as fallback.

The mpidr's type is u32, however dev_read_addr returns a value with type
fdt_addr_t(phys_addr_t) which is 64bit long. So the check never fail.
This patch we still keep mpidr as u32 type, because i.MX8 only has max
two cluster, the higher 32bit will always be 0. Use a variable addr
to do the check, if check pass, assign the lower 32 bit to plat->mpidr.

When commit 1d7993d1d0
("clk: Port Linux common clock framework [CCF] for imx6q to U-boot (tag: v5.1.12)")
introduced the parts of Linux Common Clock Framework, it was done for i.MX6
only and even had "depends on SPL_CLK_IMX6Q" conditions. Since commit
ccab06689a ("clk: imx: expose CCF entry for all") the framework can be
reused with SoCs of other vendors (say, TI), but NXP SoC-specific code is
still being build. It is especially problematic for size-constrained SPL
images on TI AM62x.
Make the build of the i.MX/RTxxxx code not only dependent on
CONFIG_$(PHASE_)CLK_CCF, but also on CONFIG_MACH_IMX options which shall
cover the i.MX platform users.
This saves 2264 bytes on 32-bit ARM platforms [using CCF].

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.

- 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

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.
