arm9 bootloader IAR

Question

I am looking for a bootloader for Atmel Arm9.

Atmel has a "Safe and secure boot loader" but that is for a ARM7 and is quite old (does not build using the latest IAR toolchain)

I am assuming that this has to be done before and don't want to reinvent the wheel

Bonus would be if the boot loader is for the Latest IAR Embedded workbench (Version 6.x)

If there is a commercial product available - that would be fine too.

Depending on the Atmel ARM9 part you are using, it may already have a bootloader in ROM, I am working with the AT91SAM9RL and the bootloader can be accessed by connecting the BMS pin to VDDIOP at power on. The embedded bootloader can then load application code from SD Card, NAND, SPI DataFlash and Serial or USB (using SAM-BA).
