The purpose of .work section

[SAeeD]

Dear all,

I've built RTEMS for my target, LPC3250 Phycore, and I wasn't able to boot
ELF file with U-Boot until I removed .work section by using "objcopy".
I was thinking what is the purpose of this section? As far as I know, it
clears the whole space of the main memory for the use of the operating
system. Is it true? Why the OS should clear whole space of memory for its
use?

Thanks in advance,
SAeeD
