How to do RamFunction in WinARM/GCC ?

Hi, I need to build a custom loader for AT91SAM7X.
Unlike the LPC21xx, this chip does not have the raw
flash programming routines supported in the ROM.
And looks like I have no choice but to run the flash
programming in SRAM.

Questions:
- Is there an easier way to do In-Application-Programming
  on AT91Sam7x Device
- How do I setup Ram functions ?? Follow the WinARM
  lpc2129_Ramfunction examples closely or there is some
  simpler way?
- I can take the .bin file from the FreeRtos+lwIP demo
  and flash it directly onto location=0x100000 without
  any modification, is that right?

Many Thanks in advance...
