+               Normally the LCD is page-aligned (tyically 4KB). If this is
+               defined then the LCD will be aligned to this value instead.
+               For ARM it is sometimes useful to use MMU_SECTION_SIZE

+               CONFIG_CONSOLE_SCROLL_LINES
+
+               When the console need to be scrolled, this is the number of

+               the console jump but can help speed up operation when scrolling
