Integrating RTEMS with ARM Cortex R4

Hi,
As far as I understood the MultiLibs for ARMv7 are present.
The following wiki page http://www.rtems.org/wiki/index.php/ARM-EABI
lists the MultiLib 4 as compatible with Cortex-A and Cortex-R variants
of the ARM CPU. Can you please elaborate on this.
Regards,
Pritesh
