OCM physical memory location?

Hello,

 

Could anyone tell me the OCM physical memory location under PetaLinux 2015.4? According to the TRM the default location is 192KB @ 0x0000000 and 64KB @ 0xfffe0000. The alternate configuration puts the OCM contiguously at 0xfffc0000.

 

If the default OCM configuration is low:

  1. Does that mean that an AMP boot image must be restricted to 192KB?
  2. Is there an example for remapping the OCM to the upper memory region?

Thanks
