Oh, my bad I'm just now seeing this.

OK. I'll try and have it finished by Thursday afternoon. conversation notes from Tim (Raptor Engineering) priority: * 2x SPI master * 4x I2C master * 2x UART * 4x LPC master * EINT* Serialsed IRQ (LPC, from PCIe) - 15 or so IRQs, these are PC>PCIe>OpenPower mappings Quad SPI raptorengineering LPC bridge github raptorengineering ~ |
