I have some questions about MVME5100. As far as i know, if mvme5100 works as mater to control other hardware, it uses VME_A**_MSTR_SIZE，VME_A**_MSTR_BUS，VME_A**_MSTR_LOCAL to realize address mapping. If mvme5100 works as slave to be controlled by other hardware, it uses
VME_A**_SLV_SIZE，VME_A**_SLV_BUS，VME_A**_SLV_LOCAL to realize address mapping.
But i don't understand how and when to use PCI_MSTR_MEM_ , PCI_MSTR_MEMIO_ , PCI_SLV_MEM_ ,PCI_SLV_MEMIO_ .If I use BLT by DMA, how does universe II and Hawk bridge realizes the address mapping step by step? And should I use PCI_MSTR_MEM_ , PCI_MSTR_MEMIO_ , PCI_SLV_MEM_ or PCI_SLV_MEMIO_ ?
