From 85e3fe12ed8df97c6a2e2d76d1db9f7cbde52d9a Mon Sep 17 00:00:00 2001 From: Shuo Liu Date: Wed, 6 Mar 2024 18:16:22 +0800 Subject: drivers/intel/fsp2_0: Use DECLARE_REGION for FSP-M heap MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There are 2 ways of referring to linker symbols, as extern u8[] or extern u8*. Only the former will be correctly initiated into an immediate operand (a constant) to asm. DECLARE_REGION defines reference in form of extern u8[]. Use DECLARE_REGION as a standard way for these references.
