Subject: [PATCH 1/1] hexagon: Don't select GENERIC_IOMAP without HAS_IOPORT support
Date: Wed,  3 Apr 2024 15:24:47 +0200	[thread overview]
Message-ID: <20240403132447.719833-2-schnelle@linux.ibm.com> (raw)
In-Reply-To: <20240403132447.719833-1-schnelle@linux.ibm.com>

In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at
compile time. As hexagon does not support I/O port access it also
the GENERIC_IOMAP mechanism of dynamically choosing between I/O port and
MMIO access doesn't work so don't select it.
