OMAP-L138: Sequence boot of OMAPL138 security

Part Number:OMAP-L138

Hi TI,

I would like change my solution for security: from normal OMAPL138 to security OMAP, E SERIES, part number is OMAPL138ZCE E. 

Right now, I dont know how to boot ARM and DSP images for this series.

With normal OMAPL138:

1. secondary boot run on ARM

2. secondary boot load arm image and DSP image

3. run DSP by write HOST1CFG register.

4. ARM run at ARM's entry point

I dont know the sequence boot on OMAPL138ZCEE and how to write secondary boot, cannot found any documents.

Please help,

Thanks,

Nhan
