f7fbe547d9 arm: mach-k3: am6_init: Use CONFIG_TI_I2C_BOARD_DETECT
We only want to call do_board_detect() if CONFIG_TI_I2C_BOARD_DETECT
is set. Same as done for am64.

This makes it possible to add a custom am65 based board design to
U-Boot that does not use this board detection mechanism.

1fd54253bc arm: a37xx: pci: Fix a3700_fdt_fix_pcie_regions() function again
The a3700_fdt_fix_pcie_regions() function still computes nonsense.

It computes the fixup offset from the PCI address taken from the first
row of the "ranges" array, which means that:
- PCI address must equal CPU address (otherwise the computed fix offset
  will be wrong),
- the first row must contain the lowest address.

This is the case for the default device-tree, which is why we didn't
notice it.

It also adds the fixup offset to all PCI and CPU addresses, which is
wrong.

Instead:
1) The fixup offset must be computed from the CPU address, not PCI
   address.

2) The fixup offset must be computed from the row containing the lowest
   CPU address, which is not necessarily contained in the first row.

3) The PCI address - the address to which the PCIe controller remaps the
   address space as seen from the point of view of the PCIe device -
   must be fixed by the fix offset in the same way as the CPU address
   only in the special case when the CPU adn PCI addresses are the same.
   Same addresses means that remapping is disabled, and thus if we
   change the CPU address, we need also to change the PCI address so
   that the remapping is still disabled afterwards.

Consider an example:
  The ranges entries contain:
    PCI address   CPU address
    70000000      EA000000
    E9000000      E9000000
    EB000000      EB000000

  By default CPU PCIe window is at:        E8000000 - F0000000
  Consider the case when TF-A moves it to: F2000000 - FA000000

  Until now the function would take the PCI address of the first entry:
  70000000, and the new base, F2000000, to compute the fix offset:
  F2000000 - 70000000 = 82000000, and then add 8200000 to all addresses,
  resulting in
    PCI address   CPU address
    F2000000      6C000000
    6B000000      6B000000
    6D000000      6D000000
  which is complete nonsense - none of the CPU addresses is in the
  requested window.

  Now it will take the lowest CPU address, which is in second row,
  E9000000, and compute the fix offset F2000000 - E9000000 = 09000000,
  and then add it to all CPU addresses and those PCI addresses which
  equal to their corresponding CPU addresses, resulting in
    PCI address   CPU address
    70000000      F3000000
    F2000000      F2000000
    F4000000      F4000000
  where all of the CPU addresses are in the needed window.

5d90836cb5 arm: dts: k3-j7200: Fix up MAIN R5FSS cluster mode back to Split-mode
The default U-Boot environment variables and design are all set up for
the MAIN R5FSS cluster to be in Split-mode. This is the setting used
when the dts nodes were originally added in v2021.01 U-Boot and the
dt nodes are synched with the kernel binding property names in
commit 468ec2f3ef ("remoteproc: k3_r5: Sync to upstreamed kernel DT
property names") merged in v2021.04-rc2.

The modes for the MAIN R5FSS cluster got switched back to LockStep mode
by mistake in commit fa09b12dc5 ("arm: ti: k3: Resync dts files and
bindings with Linux Kernel v5.14") in v2022.01-rc1. This throws the
following warning messages when early-booting the cores using default
env variables,

k3_r5f_rproc r5f@5d00000: Invalid op: Trying to start secondary core 7 in lockstep mode
Load Remote Processor 3 with data@addr=0x82000000 83148 bytes: Failed!

Fix this by switching back both the clusters to the expected Split-mode.
Make this mode change in the u-boot specific dtsi file to avoid such
sync overrides in the future until the kernel dts is also switched to
Split-mode by default.

871ee6634d arm: mvebu: spl: Add option to reset the board on DDR training failure
Some boards may occacionally fail DDR training. Currently we hang() in
this case. Add an option that makes the board do an immediate reset in
such a case, so that a new training is tried as soon as possible,
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
 still hang - it doesn't make sense to reset in such a case, because
 after reset the board will try booting from another medium, and the
 UART booting utility does not expect that.)

0c4625ac7d watchdog: armada_37xx: Convert to official DT bindings
Official DT bindings have only one reg property: watchdog address space.
Convert armada-37xx-wdt.c driver to offical DT bindings and access sel_reg
register via MVEBU_REGISTER() macro, as its value (required by U-Boot
driver) is not in DT yet. In later stage can be driver cleaned to not use
it.

This change would allow U-Boot to use A3720 watchdog DTS structure from
Linux kernel.

51f660120f arm: dts: k3-j721e-sk: EMIF tool update to 0.6.1 with 4266MTs for lpddr4
EMIF tool for J721E SK is now updated to 0.6.1 that includes
* Updated write DQ training pattern to enable user pattern and clock
  pattern (from 0x7 to 0x6).
* Updated IO drive strength to 40-80-80 Ohms.

J721E SK uses the lpddr4 configuration of 4266 MTs data rate which is
the same as J721E EVM but facing random failures. As the tool update is
specific to the SK board, add a new lpddr4 config of 4266 MTs.

7422b41175 microblaze: exception: fix delay slot exception handling
The switch statement in _hw_exception_handler() only covers the
rightmost 5 bits that encode the exception cause:
switch (state & 0x1f)
{
...
}

For this reason, the "0x1000" case will never be reached, because the 13th
bit was zeroed out. To fix this, move delay slot exception handling before
the switch statement (delay slot (DS) bit in Exception Status Register is
independent of the exception cause (EC)).
