7576ab2fac riscv: Add support for AMD/Xilinx MicroBlaze V
MicroBlaze V is new AMD/Xilinx soft-core 32bit RISC-V processor IP.
It is hardware compatible with classic MicroBlaze processor.

The patch contains initial wiring and configuration for initial HW design
with memory, cpu, interrupt controller, timers and uartlite console
(interrupt controller is listed but U-Boot is not using it).

Provided DT is just describing one configuration and should be taken only
as example.

This copies in some devicetree files from the official Linux kernel tree,
v6.6-rc6. It covers a board with the Allwinner T113s SoC, which shares

reason for the core .dtsi files landing in the arch/riscv directory.

the only compatible that should be present) and exposes the card detect
GPIO.

Note that the device trees still diverge in some places (including
important things like the PCIe controller's clock name) and should be
cleaned up so that a common device tree is used in both projects rather
than having different bindings. This patch does not attempt to do that,
merely expose important functionality present in Linux's that is not in
U-Boot's so that it can be used without the OS providing its own bundled

530f29cba5 k210: dts: align plic node with Linux
The Linux PLIC interrupt-controller driver actually initializes the hart
context registers in the PLIC driver exactly in the same order as
specified in the interrupts-extended device tree property. See the device
tree binding [1].

The ordering of the interrupts is therefore essential in order to
configure the PLIC correctly.

Fix the order so that we will have sane IRQ behavior when booting Linux
with the u-boot device tree.

3609e1dc5f dts: automatically build necessary .dtb files
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.

4027792090 riscv: qemu: Split devicetree files for qemu_riscv32/64
This uses QEMU virt which creates its own devicetree.

Copy the existing empty version of this file, so splitting the existing
qemu-virt into two, since anyone actually trying to use this will need a
different devicetree for 32- and 64-bit machines.

2e8d2f8843 riscv: Remove OF_PRIOR_STAGE from RISC-V boards
At some point back in 2018 prior_stage_fdt_address and OF_PRIOR_STAGE got
introduced,  in order to support a DTB handed over by an earlier stage boo
loader.  However we have another option in the Kconfig (OF_BOARD) which has
identical semantics.

On RISC-V some of the boards pick up the DTB from a1 and copy it in their
private gd_t.  Apart from that they copy it to prior_stage_fdt_address,  if
the Kconfig option is selected, which is unnecessary.

So let's switch the config option for those boards to OF_BOARD and define
the required board_fdt_blob_setup() for them.

This patch reverts the following commits:
 - 4b4159d0f3 ("riscv: dts: add dts for unmatched rev1")
 - ffe9a394df ("board: sifive: support spl multi-dtb on unmatched board")

We won't plan to support unmatched that the revision below 3 in u-boot,
so they can be dropped because they might be useless.

Changed in v2:
 - rebase codebase to the latest master branch
