mpc85xx: Add board support for the eXMeritus HWW-1U-1A devices
The eXMeritus HWW-1U-1A unit is a DO-160-certified 13lb 1U chassis with 3 independent TEMPEST zones. Two independent P2020 computers may be found inside each zone. Complete hardware support is included. High-level hardware overview: * DO-160 certified for passenger aircraft (noncritical) * TEMPEST ceritified for RED/BLACK separation * 3 zones per chassis, 2 computers per zone (total of 6) * Dual-core 1.066GHz P2020 per computer * One 2GB DDR2 SO-RDIMM module per computer (upgradable to 4GB) * Removable 80GB or 160GB Intel X18-M SSD per computer * Front-accessible dual-port E1000E per computer * Front-accessible serial console per computer * Front-accessible USB port per computer * Internal Gigabit crossover within each TEMPEST zone * Internal unidirectional fiber links across TEMPEST zones * Battery-backed DS1339 I2C RTC on each CPU. Combined, each 13lb 1U chassis contains 12GB RAM, 12 cores @ 1.066GHz, 12 front-accessible Gigabit Ethernet ports and 960GB of solid-state storage with a total power consumption of ~200W. Additional notes: * SPD detection is only known to work with the DO-160-certified DIMMs * CPU reset is a little quirky due to hardware misfeature. Proper support for the hardware reset mechanism has been left for a later patch series to address.
