393 Moorestown is Intel's Low Power Intel Architecture (LPIA) based Moblin
394 Internet Device(MID) platform. Moorestown consists of two chips:
395 Lincroft (CPU core, graphics, and memory controller) and Langwell IOH.
396 Unlike standard x86 PCs, Moorestown does not have many legacy devices
397 nor standard legacy replacement devices/features. e.g. Moorestown does
398 not contain i8259, i8254, HPET, legacy BIOS, most of the io ports.
