- Perform flash write opreation.\r
+ Perform flash write operation with progress indicator. The start and end\r
+ completion percentage values are passed into this function. If the requested\r
+ flash write operation is broken up, then completion percentage between the\r
+ start and end values may be passed to the provided Progress function. The\r
+ caller of this function is required to call the Progress function for the\r
+ start and end completion percentage values. This allows the Progress,\r
+ StartPercentage, and EndPercentage parameters to be ignored if the requested\r
+ flash write operation can not be broken up\r
\r
@param[in] FirmwareType The type of firmware.\r
@param[in] FlashAddress The address of flash device to be accessed.\r
@param[in] FlashAddressType The type of flash device address.\r
@param[in] Buffer The pointer to the data buffer.\r
@param[in] Length The length of data buffer in bytes.\r
+ @param[in] Progress A function used report the progress of the\r
+ firmware update. This is an optional parameter\r
