From: Clément Léger <clement.leger at linux.dev>
The barebox kvx port was upstreamed in the hope it was the first one
of a long series of other contributions (GCC, Linux, etc).
Unfortunately, the kvx architecture remained closed and there was no
public specification nor upstreamed compiler. Additionally, there are
no users outside of the company itself and there is not possible to
obtain a board with such SoC. Latest modifications of the architecture
also made it non compatible with this architecture.
As discussed during LPC, there is no point in keeping this
architecture since it is unmaintained and slows down the effort to get
Rust support on barebox. Remove the whole architecture support and
drivers as well.
Clément Léger (5):
drivers: soc: remove KVX support
drivers: clocksource: remove KVX timer
drivers: nvmem: remove KVX OTP support
drivers: watchdog: remove KVX watchdog
arch: kvx: remove support
