64-bit microcontrollers

It turns out that 32-bit microcontrollers are insufficient  They are
already 64-bit. But are these still microcontrollers or are they SoCs?
(like in smartphones and tablets). Microchip (as usual) does not
follow the "ARM way", but its own*). This time RISC-V. At this point I
would like to timidly ask "decision-makers" about the FPC compiler for
RISC-V

P.S. Chinese manufacturers (e.g. GD, WCH) have a hard life. They
barely mastered 32-bit ARM and are slowly trying to tame 32-bit
RISC-V. And here again "one of the big ones" moves the "finish line of
the race".

*) Once, when they "entered" the 32-bit microcontroller market, they
chose the MIPS architecture, while the rest of the microcontroller
manufacturers (e.g. Atmel, STM, TI) chose ARM.

RISC-V.
It's already there, for 32 and 64 bit:

With the combination CH32V and freepascal I played around, before.

There is some functional Lazarus IDE for RISC-V and Debian Trixie 64
bits?

Debian Trixie 64 has fpc and lazarus in the repo's but not sure they
are built for risc-v
But configuring the cross-compiler is no problem.

Microchip has some 64-bit "MPU"s. https://www.microchip.com/en-
us/products/microprocessors/64-bit-mpus

running yocto Linux it seems
