2.2 BSP Rel. 1.0 for PPMC-275 Programmer's Guide

Single CPU Configuration
Single CPU BSP Defines
In a single CPU BSP, the following defines in config.h are usually used
to declare the amount of memory on-board.
LOCAL_MEM_SIZE Total memory available on-board
USER_RESERVED_
MEM
Memory reserved for serial/MPSC drivers.
Setting up of BAT registers
Normally, in a Single CPU BSP, sysBatDesc (defined in sysLib.c) is
used by usrMmuInit() (called from usrConfig.c) to set up the Block
Address Translation (BAT) registers of CPU.
Setting up of Bat registers
MV64360 Resource partitioning
Exception handling
The default is to map PCI memory regions, MV64360's internal register
space and the User Flash through BATs.
Normally, in a Single CPU BSP, sysMemPhysDesc (defined in sysLib.c)
is used to by usrMmuInit() (called from usrConfig.c) to set up the
page table in memory.
In a single CPU BSP, all the resources on the system controller such as PCI,
DMA engines, timers, serial ports, Ethernet ports belong to the CPU.
Although exception-handling code is not included as a part of the BSP,
single CPU BSP handles exception in a similar manner as VxWorks.
