From 19d06b2f891a47bdaa02a5b8e60cef85313aae83 Mon Sep 17 00:00:00 2001 From: Stefan Reinauer Date: Mon, 9 Sep 2013 11:22:18 -0700 Subject: cbmem console: reduce temporary buffer size for dynamic CBMEM MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When using dynamic CBMEM the CBMEM area is initialized before entering ram stage, and so we need a way smaller temporary buffer for the CBMEM console during early bits of ram stage. In practice around 256 bytes are needed, but keep the buffer at 1k so we make sure we don't run out.
