[PATCH v1 0/4] Convert SiFive drivers from SOC_FOO dependencies to ARCH_FOO

[PATCH v1 0/4] Convert SiFive drivers from SOC_FOO dependencies to ARCH_FOO

[Conor Dooley]

From: Conor Dooley <conor.dooley@microchip.com>

RISC-V's SOC_FOO symbols for micro-archs are going away, and being
replaced with the more common ARCH_FOO pattern that is used by other
archs (and by vendors with a history outside of RISC-V).
I kicked the conversion off by converting the Microchip RISC-V bits to
use their replacement symbol, so here's round two: the various SiFive
drivers.

There are no dependencies here, everything can go via subsystem trees.
We've already added the replacement symbols to RISC-V's Kconfig bits.

Cheers,
Conor.

And this is still the wrong way around.  This ARCH_ madness must not
spread.  NAK.

As I said when you complained last, we asked the arm lads and there was no interest there in doing things differently & that's just one architecture.
Nor was there in adding a SOC_ symbol from some of the people who do more than one ISA.

You're welcome to send reverts for my first round of conversions and patches converting all the ARCH_ stuff RISC-V has to SOC_.
I'll happily ack a complete conversion to SOC_.
I don't care if it is arch or soc, I just want things to be used consistently.
