31 to break the Corelis PowerPC emulator with at least some combinations
32 of PowerPC 603e revisions and emulator versions.

37[If defined then the BSP may reduce the available memory size
38initially. This can be useful for debugging (reduce the core
39size) or dynamic loading (std gcc text offsets/jumps are < +/-32M).
40Note that the policy can still be defined by the application
41(see sbrk.c, BSP_sbrk_policy). By undefining
42CONFIGURE_MALLOC_BSP_SUPPORTS_SBRK this feature is removed
43and a little memory is saved.])
