The commit 0dba45864b ("arm: Init the debug UART") calls
debug_uart_init() from crt0.S but it won't work because SOC is not
configured yet. That's why create board_debug_uart_init() which calls
psu_init() via new psu_uboot_init() earlier before the first access to UART
in SPL. In full U-Boot call psu_uboot_init() only when
CONFIG_ZYNQMP_PSU_INIT_ENABLED is enabled.

ZYNQMP_PSU_INIT_ENABLED is called only when BOARD_EARLY_INIT_F is defined
that's why cover this dependency in Kconfig.
board_early_init_f() is only part related to
CONFIG_ZYNQMP_PSU_INIT_ENABLED which is disabled now that's why disable
BOARD_EARLY_INIT_F and also build board_early_init_f() only when
CONFIG_BOARD_EARLY_INIT_F is enabled.

U-Boot not SPL that's why build psu_spl_init for SPL all the time.
Also disable ZYNQMP_PSU_INIT_ENABLED because it ends up in situation that

instead of hanging and possibly waiting for watchdog to reset the board.
(If the DDR training fails while booting the image via UART, we will

after reset the board will try booting from another medium, and the
UART booting utility does not expect that.)

EMIF tool for AM64 SK is now updated to 0.8.0 that includes
* disabled Write DQ training
* improve CA ODT to 60 ohms
The lpddr4 enabled with periodic WDQ training is causing periodic 26us
stall. This makes the SoC stall without doing anything which leads to
R5 interrupt latency in TCM memory. Due to this periodic training there
are some outstanding CPU transactions waiting for the lpddr4 to complete.
Hence, disable the periodic write DQ training during the
non-initialization stage of lpddr4 which results in an approximate 1us
stall. Also, update the lpddr4 config to improve CA ODT by 60 ohms
The rationales are as follows:
- PI_WDQLVL_EN: 2 Bits register field to support write DQ leveling,
disable bit 1 that supports Write DQ during non-initialization to
avoid ~26us stall during code execution.
- MR11_DATA_F1/F2_x register fields value changed to 0x66 that changes
the CA ODT from 48ohm to 60ohm to improve the eye margin on CA bus by
increasing the signal swing.

When building for a custom board, it is quite common to maintain a
private branch which include some defconfig and .dts files. But to
hook up those .dts files requires modifying a file "belonging" to
upstream U-Boot, the arch/*/dts/Makefile. Forward-porting that branch
to a newer upstream then often results in a conflict which, while it
is trivial to resolve by hand, makes it harder to have a CI do "try to
build our board against latest upstream".
The .config usually includes information on precisely what .dtb(s) are
needed, so to avoid having to modify the Makefile, simply add the
files in (SPL_)OF_LIST to dtb-y.
A technicality is that (SPL_)OF_LIST is not always defined, so rework
the Kconfig symbols so that (SPL_)OF_LIST is always defined (when
(SPL_)OF_CONTROL), but only prompted for in the cases which used to be
their "depends on".
nios2 and microblaze already have something like this in their
dts/Makefile, and the rationale in commit 41f59f6853 is similar to
the above. So this simply generalizes existing practice. Followup
patches could remove the logic in those two makefiles, just as there's
potential for moving some common boilerplate from all the
arch/*/dts/Makefile files to the new scripts/Makefile.dts.

With the current configuration provided in mxsimage{-spl}.mx28.cfg the
size of SPL binary has been constrained to 32 KiB, due to "LOAD IVT"
command with 0x8000 offset.
The problem was that, the imx28 ROM takes the u-boot.sb and then
extracts from it the IVT header and places it on the 0x8000 OCRAM offset
overwriting any valid (i.e. loaded from eMMC or SPI-NOR) SPL code. This
bug was unnoticed as the overwrite size was just 32 bytes, so the
probability that some important code is altered was low.
However, in the XEA board (where the SPL size is ~39KiB), the overwritten
data was `(struct dm_spi_ops *) 0x800c <mxs_spi_ops>`, which is used
during the boot process.
As a result the SPL execution code hanged with "undefined instruction"
abort as callbacks (with wrong addresses) from it were called.
The fix is to change the OCRAM's offset where IVT is loaded to 0xE000,
so the SPL can grow up to ~57KiB (the maximal size of OCRAM memory
available is 0xE3FC).

Move this out of s_init(), into board_init_f(). Since this actually only
affects a very few older SoCs, the actual code goes into the cpu/armv7
directory, to move it out of the way for all other SoCs.
This also uses the opportunity to convert some #ifdefs over to the fancy

According to their TRMs, Cortex ARMv7 CPUs with SMP support require the
ACTLR.SMPEN bit to be set as early as possible, before any cache or TLB
maintenance operations are done. As we do those things still in start.S,
we need to move the SMPEN bit setting there, too.
This introduces a new ARMv7 wide symbol and code to set bit 6 in ACTLR
very early in start.S, and moves sunxi boards over to use that instead
of the custom code we had in our board.c file (where it was called
technically too late).
In practice we got away with this so far, because at this point all the
other cores were still in reset, so any broadcasting would have been
ignored anyway. But it is architecturally cleaner to do it early, and
we move a core specific piece of code out of board.c.
This also gets rid of the ARM_CORTEX_CPU_IS_UP kludge I introduced a few
years back, and moves the respective logic into the new Kconfig entry.

So far all Allwinner based boards were doing some not-so-lowlevel-setup
in lowlevel's s_init() routine.
This includes the initial clock, timer and pinmux setup, among other
things. This is clearly out of the "absolute bare minimum to get started"
scope that lowlevel_init.S suggests for this function.
Since we have an SPL, which is called right after s_init(), move those
calls to our board_init_f() function. As we overwrite this only for
the SPL, this has the added benefit of not doing this setup *again*
shortly afterwards, when running U-Boot proper.
This makes gpio_init() to be called from the SPL only, so pull this code
into a CONFIG_SPL_BUILD protected part to avoid build warnings.

There is some code that tries to "reset" the SCTLR_ELx register early in
the boot process. The idea seems to be to guarantee some sane settings
that U-Boot actually relies on, for instance running in little-endian
mode, with the MMU off initially.
However the current code has multiple problems:
- For a start, no platform or config defines the symbol that would
enable that code.
- The code itself really only works if the bits that it tries to clear
are already cleared:
- If we run in big-endian mode initially, any previous loads would have
been wrong already. That applies to the (optional) relocation code,
but more prominently to the mask that it uses to clear those bits:
"ldr x1, =0xfdfffffa" looks innocent, but actually involves a memory
access to the literal pool, using the current endianness.
- If we run with the MMU enabled, we are probably doomed already. We
*could* hope that we are running with an identity mapping, but would
need to do some cache maintenance to avoid losing dirty cache lines.
- The idea of doing a read-modify-write of SCTLR is somewhat
questionable to begin with, because as the owner of the current
exception level we should initialise all bits of this register with a
certain fixed value.
- The code is unnecessarily complicated, and the function name is
misspelled.
While those problems *could* admittedly be fixed, the point that is does
not seem to be used at all at the moment tells me we should just remove
this code, and be it to not give a bad example.
If people care, I could introduce some proper SCTLR initialisation code.
We are about to work this out for the boot-wrapper[1] as we speak, but
apparently we got away without doing this in U-Boot ever since, so it
might not be worth the potential trouble.

bd8a9cd624c6 ("arm64: dts: ls1028a-rdb: update copyright"), which was
chosen because some changes needed to be done to the Linux DTs too,
before they could be shared:
https://lore.kernel.org/linux-arm-kernel/20211202141528.2450169-5-vladimir.oltean@nxp.com/T/#m6f63c92e75fa79a01144b2c2c6dc4776e7971395
There are two more commits on the RDB device tree which haven't been
picked up yet, because they have dependencies on the SoC device tree:
dd3d936a1b17 ("arm64: dts: ls1028a: add ftm_alarm1 node to be used as wakeup source")
b2e2d3e02fb6 ("arm64: dts: ls1028a-rdb: enable pwm0")
These will be picked up on the next resync.

Reuse the scheme implemented by the Kontron SL28 boards in
commit d08011d7f9
("arm: dts: ls1028a: disable the PCIe controller by default")
and move the 'status = "okay"' lines for the PCIe controllers
inside a separate U-Boot dtsi for the LS1028A-RDB board. This way, the
existing Linux device tree can simply be dropped in.

There is no I2C peripheral on these buses on the reference design board,
and the Linux device tree does not enable them either.

There is no SPI peripheral on the LS1028A-RDB, therefore no reason to
enable these nodes in the U-Boot device tree (and Linux does not enable
them either).

In a bit of a blunder, the blamed commit in the Fixes: tag below made
the mscc_felix switch driver look at the 'managed = "in-band-status"'
device tree property, forgetting that the U-Boot device tree had not
been updated to include that property, whereas the Linux one does.
The switch is therefore described in the device tree as not requiring
in-band autoneg, but the PHY driver for VSC8514 (drivers/net/phy/mscc.c)
still enables that feature. This results in a mismatch => no traffic.
This patch is a copy-paste of the Ethernet device tree nodes from Linux,
which resolves that issue. The device tree update also renames the
Ethernet PHY labels.

During the LS1028A-RDB sync with Linux device trees, it was observed
that the same RTC is present on the two boards, and the wrong compatible
string is used in both places. This change updates the RTC from the
LX2160A-RDB to use the compatible string that was established in Linux.

it doesn't use the same compatible string for the RTC node as in U-Boot.
This change makes the RTC compatible strings match, for a smoother sync.

The LS1028A-QDS board won't be synced with the Linux device trees right
now, since those are currently still in progress (Ethernet is missing).
However, while we're at converting the RDB, it can be observed that the
same RTC is present on the two boards, and the wrong compatible string
is used in both places. This change updates the RTC from the QDS to use
the compatible string that was established in Linux.

Beside that mounted rgmii debug phy is 1000Mbps capable, the debug link
between the piggy board and the phy is 100Mbps only.
This leads to longer link establishment time when working in debug mode,
as phy tries to autoneg 1000Mbps.
This patch fixes the speed to 100Mbps and allows smother link establishment
time for the debug interface.
