Daniel Hellstrom 5d07b7869a sparc32,leon: add GRPCI2 PCI Host driver ... The DMA region must be accessible in order for PCI peripheral drivers to work, the sparc32 has DMA in the normal memory zone which requires the GRPCI2 to PCI target BARs so that all kernel low mem (192MB) can be mapped 1:1 to PCI address space. The GRPCI2 has resizeable target BARs, by default the first is made 256MB and all other BARs are disabled. I/O space are always located on 0x1000-0x10000, but accessed through the GRPCI2 PCI I/O Window memory mapped to virtual address space. Configuration space is accessed through the 64KB GRPCI2 PCI CFG Window using LDA bypassing the MMU. The GRPCI2 has a single PCI Window for prefetchable and non- prefetchable address space, it is up to the AHB master requesting PCI data to determine access type. Memory space is mapped 1:1. The GRPCI2 core can be configured in 4 different IRQ modes, where PCI Interrupt, Error Interrupt and DMA Interrupt are shared on a single IRQ line or at most 5 IRQs are used. The GRPCI2 can mask/unmask PCI interrupts, Err and DMA in the control and check status bits which tells us which IRQ really happended. The GENIRQ layer is used to unmask/mask each individual IRQ source by creating virtual IRQs and implementing a IRQ chip. The optional DMA functionality of the GRPCI2 is not supported by this patch.
