From 8659e4072e19130099ac4a81b204d594a6d3fb7d Mon Sep 17 00:00:00 2001 From: Kyösti Mälkki Date: Sun, 21 Dec 2014 08:55:47 +0200 Subject: CBMEM console: Fix and enhance pre-RAM support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Use the value of CONSOLE_PRERAM_BUFFER_SIZE to determine if we can do CBMEM console in bootblock and romstage. Kconfig forces it to zero if _BASE is unset or we cannot do CAR migration on x86. Add CBMEM console to bootblock, except for x86. Only one of bootblock and romstage clears the pre-RAM buffer. To start with empty console log on S3 wakeup, ramstage now clears previous contents of CBMEM buffer if there was no pre-RAM buffer. Unify Kconfig variable naming. TODO: ARM configurations do not define PRERAM_BUFFER_BASE values.
