13  * axi_sandbox_get_emul() - Retrieve a pointer to a AXI emulation device
14  * @bus:     The AXI bus from which to retrieve a emulation device

18  *	     device
19  * @emulp:   Pointer to a buffer receiving the emulation device that handles
22  * To test the AXI uclass, we implement a simple AXI emulation device, which is
23  * a virtual device on a AXI bus that exposes a simple storage interface: When
24  * reading and writing from the device, the addresses are translated to offsets
25  * within the device's storage. For write accesses the data is written to the

42  * emulation device given the AXI bus device, and the data (address, data
43  * width) of a AXI transfer which should be handled by a emulation device.
45  * Return: 0 of OK, -ENODEV if no device capable of handling the specified
46  *	   transfer exists or the device could not be retrieved
51  * axi_get_store() - Get address of internal storage of a emulated AXI device
52  * @dev:	Emulated AXI device to get the pointer of the internal storage
