Lpc2000

Thanks to all who replied!

I ended up defining a section named ram_func in the .ld file similiar
to the example from analog electronics and added "__attribute__
((section(".ram_func")));" to the headers of each function I want to
have in ram.

This works fine, and for some reason unknown for me this avoids the
compiler warnings that arrise when just declaring "__atribute__
((section(".data")));". :-)

If anybody is interested, I did the changes listed further below
compared to the default .ld file for LPC2129.

Btw, if anybody knows how to calculate the "_ramfuncetext" value
without needing to explicitly specify "- 0x40000000", I would be glad
to know how!
