Subject: AGESA vendorcode: Build a common amdlib
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Having CFLAGS with -Os disables -falign-function, for
unlucky builds this may delay entry to ramstage by 600ms.
Build the low-level IO functions aligned with -O2 instead.
