IIRC Wolfram (Cc'ed) has recently touched it.
For a programmer, it feels very much like a platform-bus (you can even use amba-devices on a platform_bus); it has the advantage of some identification registers at the end of the address-space. The rest is more about how to connect the core to the SoC. Does that help? I don't know what the actual question is :) Regards, Wolfram -- Pengutronix e.K. | Wolfram Sang | Industrial Linux Solutions | http://www.pengutronix.de/ |
