9b669ef059 arm64: dts: zynqmp: Enable nand-on-flash-bbt in DT by default
By default enable nand-on-flash-bbt DT flag, so that driver always refers
to the bad block table(bbt) present on the flash device.

749cbcfeac fpga: zynqmppl: fix fpga loads command for unencrypted use case
When using the fpga loads command, the driver is passing the AES encryption
key address is all cases.  However, for the authenticated, but not encrypted
use case, there is no AES encryption key, and this value is 0.

When AES encryption is not used on the fpga bitstream, the pmufw assumes that
the AES key address is a bitstream size value like what is used by the
unsecure fpga load command.

To fix the problem, this patch checks to see if the AES key address is zero.
If the AES key address is zero, it means that AES is not being used on the
bitstream and the bitstream size should be passed instead.  Thus, matching
the fpga load functionality.

The pl330 DMA controller provides number of DMA channels and requests
through its registers, so duplicating this information (with a chance of
mistakes) in DTS is pointless.  Additionally the DTS used always wrong
property names which causes DT schema check failures - the bindings
documented 'dma-channels' and 'dma-requests' properties without leading
hash sign.

7400d34ba9 riscv: semihosting: replace inline assembly with assembly file
So far we used inline assembly to inject the actual instruction that
triggers the semihosting service. While this sounds elegant, as it's
really only about a few instructions, it has some serious downsides:
- We need some barriers in place to force the compiler to issue writes
  to a data structure before issuing the trap instruction.
- We need to convince the compiler to actually fill the structures that
  we use pointers to.
- We need a memory clobber to avoid the compiler caching the data in
  those structures, when semihosting writes data back.
- We need register arguments to make sure the function ID and the
  pointer land in the right registers.

This is all doable, but fragile and somewhat cumbersome. Since we now
have a separate function in an extra file anyway, we can do away with
all the magic and just write that in an actual assembler.
This is much more readable and robust.

45443f6089 ram: ast2600: Keep MPLL power on
According to the PLL vendor, we should keep the PLL power on, so we
shouldn't toggle the power-down bit during PLL initialization.

94d30f476f arm64: Reduce PT size estimation complexity
count_required_pts()'s complexity is high if mappings are not using the
largest possible block size (due to some other requirement such as tracking
dirty pages, for example).

Let's switch to a method that follows the pattern established with
the add_map() helper, and make it almost instantaneous instead of
taking a large amount of time if 2MB mappings are in use instead of
1GB.

41e2787f5e arm64: Reduce add_map() complexity
In the add_map() function, for each level it populates, it iterates from
the root of the PT tree, making it ineficient if a mapping needs to occur
past level 1.

Instead, replace it with a recursive (and much simpler) algorithm
that keeps the complexity as low as possible. With this, mapping
512GB at level 2 goes from several seconds down to not measurable
on an A55 machine.

We keep the block mappings at level 1 for now though.

2c0bdcacf3 timer: fttmr010: return a previously deleted driver now ported to DM
The fttmr010 timer driver was deleted by
commit 29fc6f2492 ("ARM: remove a320evb board support")
The original source file was: arch/arm/cpu/arm920t/a320/timer.c

Return the driver to the codebase in a DM compatible form.
A platform using fttmr010 will be submitted later.

This hardware is described in the datasheet [1], starting from page 348.
According to the datasheet, there is a Revision Register at offset 0x3C,
which is not present in 'struct fttmr010'. Add it and debug() print
revision in probe function.

c55c2a8565 arm64: Initialize TLB memory if CMO_BY_VA_ONLY
Memory used to hold the page tables is allocated from the top of RAM
with no prior initialization and could therefore hold invalid data. As
invalidate_dcache_all() will be called before the MMU has been
initialized and as that function relies indirectly on the page tables
when using CMO_BY_VA_ONLY, these must be in a valid state from their
allocation.

46dc542870 arm: cpu: Add optional CMOs by VA
Exposing set/way cache maintenance to a virtual machine is unsafe, not
least because the instructions are not permission-checked but also
because they are not broadcast between CPUs. Consequently, KVM traps and
emulates such maintenance in the host kernel using by-VA operations and
looping over the stage-2 page-tables. However, when running under
protected KVM, these instructions are not able to be emulated and will
instead result in an exception being delivered to the guest.

Introduce CONFIG_CMO_BY_VA_ONLY so that virtual platforms can select
this option and perform by-VA cache maintenance instead of using the
set/way instructions.
