commit 37e5a982cf2de346be7baf37898b168eb6ed54a7 Author: Kyösti Mälkki kyosti.malkki@gmail.com Date: Sat Jan 4 09:42:02 2014 +0200
CBMEM: Fix allocation for static CBMEM
CBMEM console buffer size is adjustable in menuconfig, but this would not correctly adjust the overall allocation made for CBMEM.
HIGH_MEMORY_SIZE is aligned to 64kB and definitions are moved down in the header file as HIGH_MEMORY_SIZE is not used with DYNAMIC_CBMEM.
Try to continue boot even if CBMEM cannot be created. This error would only occur during development of new ports anyways and more log output is better.
