+               Normally the LCD is page-aligned (tyically 4KB). If this is

+               For ARM it is sometimes useful to use MMU_SECTION_SIZE

+               lines to scroll by. It defaults to 1. Increasing this makes
+               the console jump but can help speed up operation when scrolling
+               is slow.
