From f7284089e3657c66efeeb180a1f101a60d832901 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ky=C3=B6sti=20M=C3=A4lkki?= Date: Tue, 26 May 2015 10:12:45 +0300 Subject: AGESA: Split S3 backup in CBMEM MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Use separate CBMEM allocations for stack and heap on S3 resume path. The allocation of HIGH_SCRATCH_MEMORY is specific to AGESA and is moved out of globals and ACPI. This region is a replacement for BIOS_HEAP_SIZE used on non-resume paths.
