2018-01-09sun4u_iommu: update to reflect IOMMU is no longer part of the APB deviceMark Cave-Ayland1-1/+1
Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Acked-by: Artyom Tarasenko <atar4qemu@gmail.com>
2018-01-09sun4u: split IOMMU device out from apb.c to sun4u_iommu.cMark Cave-Ayland1-0/+50
By separating the sun4u IOMMU device into new sun4u_iommu.c and sun4m_iommu.h files we noticeably simplify apb.c whilst bringing sun4u in line with all the other IOMMU-supporting architectures.

2017-10-31sun4m: change TYPE_SUN4M_IOMMU macro from "iommu" to "sun4m-iommu"Mark Cave-Ayland1-1/+1
This is a legacy artifact from when the sun4m IOMMU implementation was the only IOMMU available within QEMU. Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>
2017-10-31sun4m_iommu: remove legacy sparc_iommu_memory_rw() functionMark Cave-Ayland1-16/+0
With the switch to the IOMMU memory region and DMA API, this is no longer required. Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>

2017-10-31sparc32_dma: remove is_ledma hack and replace with memory region aliasMark Cave-Ayland1-1/+1
This hack originated from before the memory region API was introduced, and increased the size of the ledma DMA device to capture incorrect accesses beyond the end of the ledma device. A full analysis can be found on Artyom's blog at http://tyom.blogspot.co.uk/2010/10/bug-in-all-solaris-versions-after-57.html. With the memory API we can now simply alias the incorrect access onto its intended destination allowing us to remove the hack.

2017-10-31sparc32_dma: introduce new SPARC32_DMA type container objectMark Cave-Ayland1-0/+12
Create a new SPARC32_DMA container object (including an appropriate container memory region) and add instances of the SPARC32_ESPDMA_DEVICE and SPARC32_LEDMA_DEVICE as child objects. The benefit is that most of the gpio wiring complexity between esp/espdma and lance/ledma is now hidden within the SPARC32_DMA realize function. Since the sun4m IOMMU is already QOMified we can find a reference to it using object_resolve_path_type() allowing us to completely remove all external references to the iommu pointer. Finally we rework sun4m's sparc32_dma_init() to invoke the new SPARC32_DMA object and wire up the remaining board memory regions/IRQs.

This makes it possible to reference the esp device from the espdma device as required, and by wiring up the device ourselves in sun4m.c we can drop use of the esp_init() function.

grlib_irqmp_create(), grlib_gptimer_create() and grlib_apbuart_create() are helpers to create and realize GRLIB devices. Their only caller leon3_generic_hw_init() doesn't check for failure. Only the first can actually fail, and only when the caller fails to set up a pointer property, which is a programming error. Replace qdev_init() by qdev_init_nofail().

Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.
