For Axon: 0x0000012a + l) Xilinx IP cores + + The Xilinx EDK toolchain ships with a set of IP cores (devices) for use + in Xilinx Spartan and Virtex FPGAs. The devices cover the whole range + of standard device types (network, serial, etc.) and miscellanious + devices (gpio, LCD, spi, etc). Also, since these devices are + implemented within the fpga fabric every instance of the device can be + synthesised with different options that change the behaviour. + + Each IP-core has a set of parameters which the FPGA designer can use to + control how the core is synthesized. Historically, the EDK tool would + extract the device parameters relevant to device drivers and copy them + into an 'xparameters.h' in the form of #define symbols. This tells the + device drivers how the IP cores are configured, but it requres the kernel + to be recompiled every time the FPGA bitstream is resynthesized. + + The new approach is to export the parameters into the device tree and + generate a new device tree each time the FPGA bitstream changes. The + parameters which used to be exported as #defines will now become + properties of the device node. In general, device nodes for IP-cores + will take the following form: + + (name)@(base-address) { + compatible = "xlnx,(ip-core-name)-(HW_VER)" + [, (list of compatible devices), ...]; + reg = <(baseaddr) (size)>; + interrupt-parent = <&interrupt-controller-phandle>; + interrupts = < ... >; + xlnx,(parameter1) = "(string-value)"; + xlnx,(parameter2) = <(int-value)>; + }; + + (ip-core-name): the name of the ip block (given after the BEGIN + directive in system.mhs).
