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.
