Subject: [PATCH v2 09/19] ARM: update FPE_NWFPE help text
Date: Wed,  1 Jul 2026 23:23:43 +0200	[thread overview]
Message-ID: <20260701212353.2196041-10-arnd@kernel.org> (raw)
In-Reply-To: <20260701212353.2196041-1-arnd@kernel.org>

From: Arnd Bergmann <arnd@arndb.de>

The help text is seriously outdated and predates the introduction of
VFP floating point units that were available as early as some ARM926
based systems.

Change the help text to reflect that this is now a legacy feature
and that it will go away along with OABI support in the future.

Acked-by: Linus Walleij <linus.walleij@linaro.org>

 	  Say Y to include the NWFPE floating point emulator in the kernel.
-	  This is necessary to run most binaries. Linux does not currently
-	  support floating point hardware so you need to say Y here even if
-	  your machine has an FPA or floating point co-processor podule.
 
-	  You may say N here if you are going to load the Acorn FPEmulator
-	  early in the bootup.
+	  This is only used on OABI userspace binaries, either using a
+	  pure OABI (!CONFIG_AEABI) kernel, or the OABI emulation.
+
+	  Support for NWFPE will be removed in the future when OABI
+	  support is removed.
