The co-processor has several limits regarding the length of scatter/gather lists and the total number of bytes in it. These limits are available in the device tree, as following: - "ibm,max-sg-len": maximum number of bytes of each scatter/gather list. - "ibm,max-sync-cop": used for synchronous operations, it is an array of structures that contains information regarding the limits that must be considered for each mode and operation. The most important limits in it are: - The total number of bytes that a scatter/gather list can hold. - The maximum number of elements that a scatter/gather list can have. This patch updates the NX driver to perform several hyper calls if needed in order to always respect the length limits for scatter/gather lists.
