From 04bb48008e5a2b2eb2640a1053f934de83680ecb Mon Sep 17 00:00:00 2001 From: Naresh G Solanki Date: Tue, 13 Dec 2016 21:16:46 +0530 Subject: x86: Configure premem cbmem console size Sometime preram cbmem logs are truncated due to lack of space (default preram cbmem console size is 0xc00). Provide Kconfig option to configure preram cbmem console size so that mainboard can configure it to required value.
