From deebd9466f3fab66fe6e5f4ebbbc254c7d1cea0b Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Mon, 8 May 2023 10:29:42 +0000 Subject: =?UTF-8?q?soc/intel/meteorlake:=20Apply=20large=C2=A0cbmem=20buff?= =?UTF-8?q?er=20size=20for=20FSP=20debug?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch ensures that the PRERAM_CBMEM_CONSOLE_SIZE and CONSOLE_CBMEM_BUFFER_SIZE hold a larger cbmem buffer size to contain the entire FSP debug serial log. The existing implementation was not appropriate, where the larger cbmem size was even applicable for serial AP firmware (w/o FSP debug) image as well. This change is necessary to ensure that the FSP debug serial log is always available, even in cases where the cbmem buffer size is limited. BUG=b:280481298 TEST=Able to build and boot google/rex with non-FSP serial AP image and with FSP serial AP image. Able to see the AP log completely inside the cbmem.
