net: rswitch: Add missing cache invalidate of TX descriptor
TFTP transfers of large files, for example 128 MiB, can sporadically
get stuck and the transfer slows down considerably.
This happens because the TX DMA descriptor in DRAM becomes out of sync
with the view of the TX DMA descriptor content from the CPU side, which
is viewed through the CPU caches. In order to guarantee these two views
are consistent, the cache over TX DMA descriptor that has possibly been
written by the rswitch hardware must first be invalidated, only then can
the descriptor be cleared and updated by the CPU, and finally the cache
over that area must be flushed back into DRAM to make sure the rswitch
hardware has consistent view of the updated descriptor content.
The very first invalidation operation was missing, which led to sporadic
corruption of the TX DMA descriptor. Fix it, add the missing invalidation
operation.

clk: renesas: r8a779h0: Drop CLK_PLL2_DIV2 to clarify ZCn clocks
Early revisions of the R-Car V4M Series Hardware User’s Manual
contained an incorrect formula for the CPU core clocks:
ZCnφ = (PLL2VCO x 1/2) x mult/32
Dang-san fixed this by using CLK_PLL2_DIV2 instead of CLK_PLL2 as the
parent clock.
In Rev.0.70 of the documentation, the formula was corrected to:
ZCnφ = (PLL2VCO x 1/4) x mult/32
As the CPG Block Diagram now shows a separate 1/4 post-divider for PLL2,
the use of CLK_PLL2_DIV2 is a recurring source of confusion. Hence get
rid of CLK_PLL2_DIV2, and include the proper 1/4 post-divider in the
invocation of the DEF_GEN4_Z() macro, like is done on other R-Car Gen4
(and Gen3) SoCs.

imx: Fix usable memory ranges for imx8m SOCs
commit e27bddff4b97 ("imx8m: Restrict usable memory to space below 4G boundary")
tried to adjust the usable memory limits on a 4GB boundary.
ram_top is described as 'top address of RAM used by U-Boot' and we want
to preserve that. This is defined as a phys_addr_t and unfortunately
its size differs across architectures. This has lead us to a weird
state where 32bit boards define it 'SZ_4GB - 1' and 64bit boards as
'SZ_4GB' unless it was otherwise defined.
With some recent LMB changes and specifically
commit 1a48b0be93d4 ("lmb: prohibit allocations above ram_top even from same bank")
the board fails to boot properly although the commit above is correct
since it's making sure that no memory above ram_top is usable -- but
added to our memory map so EFI can hand it over to the booted OS.
The reason for that is that during the LMB init we add all usable memory
in lmb_add_memory(). In that function any memory above ram_top gets added
as 'reserved' for LMB. With the current values tha's set to 0xFFFF_FFFF
for this board. Later LMB is trying to protect the memory area U-Boot lives
in with lmb_reserve_common(). The latter fails though since it tries to
add U-Boot top (which is 0xFFFF_FFFF as well) to U-Boot 'bottom'. This call
will fail since 1 byte of that memory range is already marked as 'reserved'.
Since we are close to the release, LMB seems to assume that the address
is rounded up and is the 'next address' and so does parsing and adding
memory ranges from DT files, bump the ram_top of the board by 1byte.
In the long run we should change all of the above and have 32b and 64b
platforms define ram_top identically.
Add a Fixes tag although the commit is correct, so people can figure out
the broken scenarios in the future.

That consequently leads to the attempt of reserving the same memory

output of 'booti' command on E850-96 board:
The mentioned false positive error messages are observed starting with

regular errors. That in turn may lead to incorrect error handling in the
caller code, like reporting misleading errors or interrupting the normal

As this signal is be default an input, and can optionally be switched to
an output, it maps neatly onto an `output-enable` property in the device
tree.

pinctrl: rzg2l: Support 2.5V PVDD for Ethernet interfaces
The Ethenet interfaces on the Renesas RZ/G2L SoC family can operate at
multiple power supply voltages: 3.3V (default value), 2.5V and 1.8V.
rzg2l_pinconf_set() is extended to support the 2.5V setting, with a
check to ensure this is only used on Ethernet interfaces as it is not
supported on the SD & QSPI interfaces.
While we're modifying rzg2l_pinconf_set(), drop the unnecessary default
value for pwr_reg as it is set in every branch of the following if
condition.

clk: rzg2l: Ignore enable for core clocks
In the RZ/G2L family, core clocks are always on and can't be disabled.
However, drivers which are shared with other SoCs may call clk_enable()
or clk_enable_bulk() for a clock referenced in the device tree which
happens to be a core clock on the RZ/G2L. To avoid the need for
conditionals in these drivers, simply ignore attempts to enable a core
clock.

When MbedTLS TLS features were added MBEDTLS_HAVE_TIME was defined as part
of enabling https:// support. However that pointed to the wrong function
which could crash if it received a NULL pointer.
Looking closer that function is not really needed, as it only seems to
increase the RNG entropy by using 4b of the current time and date.
The reason that was enabled is that lwIP was unconditionally requiring it,
although it's configurable and can be turned off.
Since lwIP doesn't use that field anywhere else, make it conditional and
disable it from our config.

lmb: prohibit allocations above ram_top even from same bank
There are platforms which set the value of ram_top based on certain
restrictions that the platform might have in accessing memory above
ram_top, even when the memory region is in the same DRAM bank. So,
even though the LMB allocator works as expected, when trying to
allocate memory above ram_top, prohibit this by marking all memory
above ram_top as reserved, even if the said memory region is from the
same bank.

Two fixes for the EFI subsystem coming via the TPM tree as agreed by Heinrich
The LMB patch fixes a failure in SystemReady testing. Nothing bad happens
without the patch in the device operation, but the return values are wrong
and SCT tests fail for MemoryAllocationServicesTest category.
The second is a shielding the device against mistakes in the definition of
struct fields needed by the capsule update mechanism. Instead of crashing,
print a humna readable message of what's wrong.
lmb: Fix the allocation of overlapping memory areas with !LMB_NONE
At the moment the LMB allocator will return 'success' immediately on two
consecutive allocations if the second one is smaller and the flags match
without resizing the reserved area.
This is problematic for two reasons, first of all the new updated
allocation won't update the size and we end up holding more memory than
needed, but most importantly it breaks the EFI SCT tests since EFI
now allocates via LMB.
More specifically when EFI requests a specific address twice with the
EFI_ALLOCATE_ADDRESS flag set, the first allocation will succeed and
update the EFI memory map. Due to the LMB behavior the second allocation
will also succeed but the address ranges are already in the EFI memory
map due the first allocation. EFI will then fail to update the memory map,
returning EFI_OUT_OF_RESOURCES instead of EFI_NOT_FOUND which break EFI
conformance.
So let's remove the fast check with is problematic anyway and leave LMB
resize and calculate address properly. LMB will now
- try to resize the reservations for LMB_NONE
- return -1 if the memory is not LMB_NONE and already reserved
The LMB code needs some cleanup in that part, but since we are close to
2025.01 do the easy fix and plan to refactor it later.
Also update the dm tests with the new behavior.

efi_loader: Check for a valid fw_name before auto generating GUIDs
The gen_v5_guid() is a void and does no error checking with pointers
being available etc. Instead it expects all things to be in place to
generate GUIDs. If a board capsule definition is buggy and does not
define the firmware names when enabling capsule updates, the board will
crash trying to bring up the EFI subsystem.
Check for a valid firmware name before generating GUIDs.
