From: Chris Wulff <crwu...@gmail.com> This set of patches adds support for the Altera NiosII soft-core processor. Included are support for the CPU core and the drivers needed to boot Linux (Interrupt controller, Timer and Serial port.) There are quite a few changes suggested by the first round review. These include:
* Better CPU code generation * Better support for QOM * A bunch of coding style cleanups (struct naming, merging GDB imported disassembly, etc.) * Updated for changes to the current head of the tree I've also dropped the device-tree based board configurations from this patch set. Those currently depend heavily on fdt-generic patches from Peter Crosthwaite that have yet to make it into the main tree. This set of patches builds the NiosII core without errors but will report no machine found. I will resubmit those board configurations under a separate patch set once the integration and cleanup is complete for the fdt-generic board configurations is completed. Chris Wulff (4): NiosII: Add support for the Altera NiosII soft-core CPU. NiosII: Disassembly of NiosII instructions ported from GDB. Altera: Add support for devices needed to boot Linux on NiosII. NiosII: Build system and documentation integration.
