P4080 PCIe Adapter SDK User Guide Production Release

Freescale Semiconductor
* to P4080 PCIE domain into Host domain address. The converted address will be
* the PCIe address in Host domain that when accessed by host software in
* the Host->P4080 direction, gets translated into P4080 PCIe domain using
* inbound ATMU. 64MB DMA memory on P4080 is mapped into Host Domain.
*
* @p4080_address – Address belongs to P4080 domain.
*
* @return – Address belongs to Host domain.
*/
The Prototype of this API is as follows
unsigned long convert_p4080_add_to_host_virt(unsigned long p4080_address);
p4080_address – Address in P4080 domain that needs to be converted into Host
domain address.
/**
* API: read_p4080_ccsr : Reads value of a register from P4080’s CCSR.
*
* @register_offset – Offset of a register in CCSR space
* @value – Value that is read from CCSR space
*
*/
The prototype of this API is as follows
void read_p4080_ccsr(int register_offset, u32 *value);
register_offset – Offset of a register in CCSR space that needs to be read from CCSR
space.
value – Value obtained from the register at offset “register_offset” in P4080 CCSR
space.
/**
* API: write_p4080_ccsr : Writes a value into P4080 CCSR.
*
* @register_offset – Offset of a register in CCSR space
* @value – Value that is to be written into CCSR space
