@neonix: Do you have specific hardware in mind?
piCore is
intended solely for the Raspberry Pi boards. Whether or not you can get it to run on other hardware becomes a project which scopes outside of the Tiny Core Linux support region, but doesn't stop anyone from experimenting and/or implementing it to their wishes. Last I knew, there were no RasPi boards (or plans for) running ARMv9.
ARMv9 was a discussion on raspberrypi.com back in 2021 where someone had asked the same question to RasPi peeps: Will ARMv9 ever be a Pi Platform.
Good reads:

Additionally, there are claims ARMv9 uses the same ARMv8x ASM (plus potential additions) so in theory, piCore15 is already somewhat ARMv9 friendly - but no way to prove it yet as there's no board to prove it
on and tweak to perfection.
Now, if the Admins all got together and said "Hey, why don't we support this and that
non-raspi ARM board?" that would be a different story, but still, they'd need physical boards to develop for and test on
in their possession, otherwise it's a guessing game nobody wins.
