All functions getting and setting clock rate use ulong for rate, only
clk_get_parent_rate is an exception. Change the return value to match
other clock rate funcrions.
Most users directly assign the rate to unsigned long anyway, and the few
users that use u64 (not s64) multiply the rate so they may need the
extra bits for the result in their use case.

The situation is similar to commit bf6376642f ("board: ti: common:
board_detect: Fix EEPROM read quirk"). This is seen on a variant of
eeproms seen on some BeagleBone-AI64 which now has a mix of both 1 byte
addressing and 2 byte addressing eeproms.
Unlike the am335x (ti_i2c_eeprom_am_get) and dra7
(ti_i2c_eeprom_dra7_get) which use constant data structure which allows
us to do a complete read of the data, the
am6(ti_i2c_eeprom_am6_get) eeprom parse operation is dynamic.
This removes the option of being able to read the complete eeprom data
in one single shot.
Fortunately, on the I2C bus, we do see the following behavior: In 1
byte mode, if we attempt to read the first header data yet again, the
misbehaving 2 byte addressing device acts in constant addressing mode
which results in the header not matching up and follow on attempt at 2
byte addressing scheme grabs the correct data.
This costs us an extra ~3 milliseconds, which is a minor penalty
compared to the consistent image support we need to have.

Commit c0fce929564f("vexpress64: fvp: enable OF_CONTROL") added code to
consider a potential DTB address being passed in the x0 register, or
revert to the built-in DTB otherwise.
The former case was used when using the boot-wrapper, to which we sell
U-Boot as a Linux kernel. The latter was meant for TF-A, for which we
couldn't find an easy way to use the DTB it uses itself. We have some
quirk to filter for a valid DTB, as TF-A happens to pass a pointer to
some special devicetree blob in x0 as well.
Now the TF-A case is broken, when enabling proper emulation of secure
memory (-C bp.secure_memory=1). TF-A carves out some memory at the top
of the first DRAM bank for its own purposes, and configures the
TrustZone DRAM controller to make this region secure-only. U-Boot will
then hang when it tries to relocate itself exactly to the end of DRAM.
TF-A announces this by carving out that region of the /memory node, in
the DT it passes on to BL33 in x1, but we miss that so far.
Instead of repeating this carveout in our DT copy, let's try to look for
a DTB at the address x1 points to as well. This will let U-Boot pick up
the DTB provided by TF-A, which has the correct carveout in place,
avoiding the hang.
While we are at it, make the detection more robust: the length test (is
the DT larger than 256 bytes?) is too fragile, in fact the TF-A port for
a new FVP model already exceeds this. So we test x1 first, consider 0
an invalid address, and also require a /memory node to detect a valid DTB.
And for the records:
Some asking around revealed what is really going on with TF-A and that
ominous DTB pointer in x0: TF-A expects EDK-2 as its non-secure payload
(BL33), and there apparently was some long-standing ad-hoc boot protocol
defined just between the two: x0 would carry the MPIDR register value of
the boot CPU, and the hardware DTB address would be stored in x1.
Now the MPIDR of CPU 0 is typically 0, plus bit 31 set, which is defined
as RES1 in the ARMv7 and ARMv8 architectures. This gives 0x80000000,
which is the same value as the address of the beginning of DRAM (2GB).
And coincidentally TF-A put some DTB structure exactly there, for its
own purposes (passing it between stages). So U-Boot was trying to use
this DTB, which requires the quirk to check for its validity.

- gpio_wdt: use __udelay() to avoid recursion (Rasmus)
- watchdog: max6370: use __udelay() to avoid recursion (Pali)
Currently, AUTOBOOT_KEYED and its variant AUTOBOOT_ENCRYPTION are
broken when one has an external always-running watchdog device with a
timeout shorter than the configured boot delay (in my case, I have a
gpio-wdt one with a timeout of 1 second), because we fail to call
WATCHDOG_RESET() in the loops where we wait for the bootdelay to
elapse.
This is done implicitly in the !AUTOBOOT_KEYED case,
i.e. abortboot_single_key(), because that loop contains a
udelay(10000), and udelay() does a WATCHDOG_RESET().
To fix this, simply add similar udelay() calls in the other loops.

The udelay() function in lib/time.c contains a WATCHDOG_RESET()
call. The only reason this doesn't lead to a catastrophic infinite
recursion is due to the rate-limiting in wdt-uclass.c:
if (time_after_eq(now, priv->next_reset)) {
priv->next_reset = now + priv->reset_period;
wdt_reset(dev);
}
But this would fall apart if ->next_reset was updated after calling the
device's reset method.
This is needlessly fragile, and it's easy enough to avoid that
recursion in the first place by just using __udelay() directly.

After inspecting the content of the memory location that corresponds to
the DTB load address, the content did not match with the DTB binary,
showing that some kind of memory corruption/overlap occurred.
Letting the CONFIG_SPL_FIT_IMAGE_TINY option to be selected causes the
DTB to be properly placed into RAM and no more overlap occurs.
With this change, the 'hab_status' command returns no more error events,
which indicates that the BootROM succeeded to authenticate the SPL.

The fdt command currently handles stringlists as strings in 'fdt get value'
subcommand. Since strings in FDT stringlists are separated by '\0', only
the first value gets inserted into the environment variable passed to the
'fdt get value' command.
Example, consider the following DT snippet:
/ { compatible = "foo", "bar" };
The following command only reports the first string in stringlist:
=> fdt get value var / compatible ; print var
foo
It is not possible to assign list of null-terminated strings into U-Boot
environment variable. Add optional 'index' parameter to the subcommand
'fdt get value <var> <path> <prop> [<index>]' which lets user specify which
string within the stringlist should be assigned into the 'var' variable.
The default value of 'index' is 0 in case it is not present. This way the
'fdt' command API does not change and existing scripts are not broken.
The following command now reports the Nth string in stringlist, counting
from zero:
=> fdt get value var / compatible 1 ; print var
bar
