At present this leaves the stack at the pre-relocation value. This is not
ideal since we want to have U-Boot running entirely from the top of
memory.
In addition, the new global_data pointer is not actually used, since
the global_data pointer itself is relocated, then the pre-relocation value
is changed, so the effective value (after relocation) does not update.
Adjust the implementation to follow the 32-bit code more closely, with a
trampoline function which is passed the new stack and global_data pointer.
This ensures that the correct values come through even when relocating.

Flushing kernel image after decompression was taking 113 milliseconds
with U-boot 2022.10. With U-boot 2023.01 and 2023.04, flushing
the same amount of memory takes approx 1.5 seconds. With
U-boot 2023.07-rc6, it takes 6.5 seconds.
powerpc flush_cache() function used to call WATCHDOG_RESET() after
flushing every cacheline. At that time WATCHDOG_RESET() was light
so the operation was almost seamless.
But commit 29caf9305b ("cyclic: Use schedule() instead of
WATCHDOG_RESET()") replaced WATCHDOG_RESET() by schedule() and that
started to hurt with U-boot 2022.10.
And in U-boot 2023.07-rc6 that's even worse after
commit 26e8ebcd7c ("watchdog: mpc8xxx: Make it generic").
In the meantime commit 729c1fe656 ("powerpc: introduce
CONFIG_CACHE_FLUSH_WATCHDOG_THRESHOLD") gives us the opportinity to
only call schedule() every given chunk of data instead of every
cacheline. As explained in that commit there is no point in pinging
the watchdog after every cacheline flush, so lets define a sensible
default chunk size of 4k which matches to size of a page on most
powerpc platforms.
With that new default threshold, the culprit flushing performed after
kernel image decompression now takes 85 milliseconds on a powerpc 8xx.

The ADIN1300 datasheet indicate that the "Management interface

deasserted.
The device tree in Variscite custom git repository uses the following
property:
phy-reset-post-delay = <20>;
Add a new MDIO property 'reset-deassert-us' of 20ms to have the same
delay inside the ethphy node. Adding this property fixes the problem
with the PHY detection.
Note that this SOM can also have an Atheros AR8033 PHY. In this case,
a 1ms deassert delay is sufficient. Add a comment to that effect.

After the commit (SHA1: 7d08ddd09b) some
u-boot specific XEA FEC related properties have been replaced by ones
from the Linux kernel.
To be more specific - XEA board (and imx287 in general) has built L2
switch connected to FEC, which needs some special treatment.
In u-boot it is handled with 'mac0' node, whereas Linux uses dedicated
switch DTS node.

After the re-sync with Linux Kernel's DTS
(SHA1: 7d08ddd09b), the XEA's
descripion has nodes and properties, which are NOT utilized
in the u-boot.
To avoid confusion - those are deleted.

The IMX28 PMU (Power Management Unit) has a dedicated Linear Regulator
to produce (by default) 4.2V output - available outside the chip as
VDD_4P2.
When system is supposed to not use VDD5V as a main power source - instead
the DCDC_BATT is used; it is safe to disable this regulator.
As the in-PMU DCDC switching regulator (from which DCDC_VDDA, DCDC_VDDIO
and DCDC_VDDD are generated) can be driven from DCDC_BATT or output
of this 4P2 regulator - by disabling the latter the use of the DCDC_BATT
is forced.
To be more specific - according to NXP's AN4199 the DCDC_BATT source is
preferred (over VDD5V), as more efficient and stable source for
industrial applications.

This new Kconfig option allows disabling the in-PMU battery charging
block. This may be required when DCDC_BAT source is powered not from
battery, but from already regulated, good quality source.

This option sets the current limit for 5V source to zero, so all
the PMU outputs are primarily powered from battery source (DCDC_BAT).
This option may be set on systems, where the 5V is NOT supposed to be
in any scenario powering the system - for example on systems where
DCDC_BAT is connected to fixed and regulated 4.2V source (so the
"battery" is not present).
