Subject: [PATCH 6/6] Platforms/Marvell/Armada70x0Lib: switch to ASM_FUNC() asm macro
Date: Thu, 11 Aug 2016 12:08:21 +0200	[thread overview]
Message-ID: <1470910101-20322-7-git-send-email-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <1470910101-20322-1-git-send-email-ard.biesheuvel@linaro.org>

Annotate functions with ASM_FUNC() so that they are emitted into
separate sections.

While we're at it, clean up some inefficient uses of LoadConstantToReg()
(which require runtime relocation).
