/*
 * sysBatDesc[] is used to initialize the block address translation (BAT)
 * registers within the PowerPC 603/604 MMU.  BAT hits take precedence
 * over Page Table Entry (PTE) hits and are faster.  Overlap of memory
 * coverage by BATs and PTEs is permitted in cases where either the IBATs
 * or the DBATs do not provide the necessary mapping (PTEs apply to both
 * instruction AND data space, without distinction).
 *
 * The primary means of memory control for VxWorks is the MMU PTE support
 * provided by vmLib and cacheLib.  Use of BAT registers will conflict
 * with vmLib support.  User's may use BAT registers for i/o mapping and
 * other purposes but are cautioned that conflicts with cacheing and mapping
 * through vmLib may arise.  Be aware that memory spaces mapped through a BAT
 * are not mapped by a PTE and any vmLib() or cacheLib() operations on such
 * areas will not be effective, nor will they report any error conditions.
 *
 * Note: BAT registers CANNOT be disabled - they are always active.
 * For example, setting them all to zero will yield four identical data
 * and instruction memory spaces starting at local address zero, each 128KB
 * in size, and each set as write-back and cache-enabled.  Hence, the BAT regs
 * MUST be configured carefully.
 *
 * With this in mind, it is recommended that the BAT registers be used
 * to map LARGE memory areas external to the processor if possible.
 * If not possible, map sections of high RAM and/or PROM space where
 * fine grained control of memory access is not needed.  This has the
 * beneficial effects of reducing PTE table size (8 bytes per 4k page)
 * and increasing the speed of access to the largest possible memory space.
 * Use the PTE table only for memory which needs fine grained (4KB pages)
 * control or which is too small to be mapped by the BAT regs.
 *
 * All BATs point to PROM/FLASH memory so that end customer may configure
 * them as required.

 * sysPhysMemDesc[] is used to initialize the Page Table Entry (PTE) array

 * PTE memory space should not, in general, overlap BAT memory space but
 * may be allowed if only Data or Instruction access is mapped via BAT.
 *
 * Address translations for local RAM, memory mapped PCI bus, the Board Control and
 * Status registers, the MPC8260 Internal Memory Map, and local FLASH RAM are set here.
 *
 * PTEs are held, strangely enough, in a Page Table.  Page Table sizes are
 * integer powers of two based on amount of memory to be mapped and a
 * minimum size of 64 kbytes.  The MINIMUM recommended Page Table sizes
