[FEATURE/OFW] add address reverse/translate for DMA/CPU's address

2024-09-13T21:33:29Z

DMA and CPU address view is different, we need to convert them: +--------+ +--------+ +---------+ +--------+ | | | | | | | | | CPUs | | DEV0 | | IOMMU <----+ | DEV1 | | | | | | | | | | +----+---+ +----+---+ +----+----+ | +----+---+ | | | | | 0x200000 | 0x1000 | 0x1000 | | 0x8000 | | | | | | +-------------+-----------+ +----------+ | | +--------v----------------------------------------------------+ | | | Address BUS | | | +-------------------------------------------------------------+ Signed-off-by: GuEe-GUI <2991707448@qq.com>

[OFW] io ranges use list to storage without ofw data (#8993)

2024-05-28T06:25:09Z

[OFW] io ranges use ptr array to storage without ofw data ofw data is private data for every ofw node that the drivers of ofw node will use item. replace the ranges supported to a ptr array. the ptr array size is config by `RT_USING_OFW_BUS_RANGES_NUMBER` Signed-off-by: GuEe-GUI <2991707448@qq.com>

Drivers: Support Open Firmware API and model of PIC

2023-07-05T08:45:16Z

We support OFW API to replace fdt old API, and add IRQ, IO, Platform-Bus, CPUs ... OFW node contorl. To support work with Device Tree or ACPI in drivers that use IRQ, we make a programmable interrupt controller driver's model. Signed-off-by: GuEe-GUI
