[bsp/raspberry-pi] update DM support

2026-08-16T11:56:03Z

- reorganize common Raspberry Pi drivers under the device framework - add the Raspberry Pi 5 BSP, configuration and documentation - add BCM2712 and DesignWare AXI DMA controller support - distinguish BCM2712 DMA32 and DMA40 channels by channel mask - restore DesignWare AXI DMA enable bits after controller reset - support a shared AXI maximum burst length across DMA channels Signed-off-by: GuEe-GUI <2991707448@qq.com>

[dm][dma] Update DMA (#11678)

2026-08-14T04:42:01Z

* [dm][dma] update DMA interface Extend DMA mapping to honor OFW dma-ranges even when no reserved memory pool is present, and add PCI host-bridge DMA-region translation for PCI devices. Prefer 32-bit-addressable allocations for translated devices, improve pool allocation fallbacks and synchronization, and establish a linear mapping for installed DMA pools when possible. Signed-off-by: GuEe-GUI <2991707448@qq.com> * [dm][dma] fixup PL330 work flow Fix PL330 channel allocation so device-tree cells select peripheral request lines rather than execution channels. Generate proper peripheral DMA microcode using DMAWFP, DMALDP, DMASTP, and DMAFLUSHP, encode burst lengths correctly, honor transfer direction and non-secure attributes, and allocate microcode from DMA-coherent memory.
