s32 XCfupmc_CfgInitialize | ( | XCfupmc * | InstancePtr, |
XCfupmc_Config * | CfgPtr, | ||
u32 | EffectiveAddr | ||
) |
This function initializes an CFU core.
This function must be called prior to using an CFU driver.
InstancePtr | is a pointer to the XCfupmc instance. |
CfgPtr | is a reference to a structure containing information about a specific XCfupmc instance. |
EffectiveAddr | is the device base address in the virtual memory address space. The caller is responsible for keeping the address mapping from EffectiveAddr to the device physical base address unchanged once this function is invoked. Unexpected errors may occur if the address mapping changes after this function is called. If address translation is not used, pass in the physical address instead. |

void XCfupmc_CfiErrHandler | ( | XCfupmc * | InstancePtr | ) |
