Let me ask my question in another way: I'm running an ELF file on PHYCORE 
LPC3250. The board has 64 MB of SRAM. This is while the ELF file has a .Work 
section with a size around 63 MB:
Clearing .work @ 0x80101d60( 66036384 bytes)

What does it mean!? RTEMS is clearing almost whole space of SRAM for use?
