To ease the implementation of other MPC85xx board ports, several common GPIO helpers are added to <asm/mpc85xx_gpio.h>.

Since each of these compiles to no more than 4-5 instructions it would be very inefficient to call them out of line, therefore we put them entirely in the header file.

The HWW-1U-1A board port which these were written for strongly prefers to set multiple GPIOs as a single batch operation, so the API is designed around that basis.

To assist other board ports, a small set of wrappers are used which provides a standard gpio_request() interface around the MPC85xx-specific functions. This can be enabled with CONFIG_MPC85XX_GENERIC_GPIO

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

* A U-Boot built with 36-bit address-space seems to work, but I don't yet have a usable 36-bit kernel or DTB, so it's mostly untested.

* CPU reset is a little quirky due to hardware misfeature, see the extensive comments in the board_reset() function in hww1u1a.c
