lib: utils/irqchip: plic: Ensure no out-of-bound access in context save/restore helpers

2022-12-17T03:33:30Z

Currently the context save/restore helpers writes/reads the provided array using an index whose maximum value is determined by PLIC, which potentially may disagree with the caller to these helpers. Add a parameter to ask the caller to provide the size limit of the array to ensure no out-of-bound access happens. Signed-off-by: Bin Meng Reviewed-by: Anup Patel

platform: generic: Add Renesas RZ/Five initial support

2022-12-12T13:20:56Z

This commit provides basic support for the Renesas RZ/Five (R9A07G043F) SoC. The RZ/Five microprocessor includes a single RISC-V CPU Core (Andes AX45MP) 1.0 GHz, 16-bit DDR3L/DDR4 interface. Supported interfaces include: - Gigabit Ethernet 2ch - CAN interface (CAN-FD) 2ch - USB 2.0 interface 2ch - SD interface 2ch - AD converter 2ch Useful links: ------------- Links: https://www.renesas.com/us/en/products/microcontrollers-microprocessors/rz-mpus/rzfive-risc-v-general-purpose-microprocessors-risc-v-cpu-core-andes-ax45mp-single-10-ghz-2ch-gigabit-ethernet Links: http://www.andestech.com/en/products-solutions/andescore-processors/riscv-ax45mp/ Signed-off-by: Lad Prabhakar Reviewed-by: Anup Patel

platform: generic: Make use of fdt_match_node()

2022-12-09T05:43:00Z

It makes sense to use fdt_match_node() instead of fdt_find_match() in fw_platform_lookup_special() as we already have the start offset to search from. Signed-off-by: Lad Prabhakar Reviewed-by: Anup Patel

platform: generic/andes: Enable generic platform support for AE350

2022-12-05T11:54:32Z

We move andes directory to platform/generic as the necessary fdt drivers are available, the users can enable the console, timer, ipi, irqchip and reset devices by adding device tree nodes stated in the docs/platform/andes-ae350.md.

lib: utils/ipi: Add Andes fdt ipi driver support

2022-10-23T05:01:01Z

Move Andes PLICSW ipi device to fdt ipi framework, this patch is based on Leo's modified IPI scheme on PLICSW. Current IPI scheme uses bit 0 of pending reigster on PLICSW to send IPI from hart 0 to hart 7, but bit 0 needs to be hardwired to 0 according to spec. After some investigation, self-IPI seems to be seldom or never used, so we re-order the IPI scheme to support 8 core platforms. dts example (Quad-core AX45MP): plicsw: interrupt-controller@e6400000 { compatible = "andestech,plicsw"; reg = <0x00000000 0xe6400000 0x00000000 0x00400000>; interrupts-extended = <&CPU0_intc 3 &CPU1_intc 3 &CPU2_intc 3 &CPU3_intc 3>; interrupt-controller; #address-cells = <2>; #interrupt-cells = <2>; }; Signed-off-by: Yu Chien Peter Lin Reviewed-by: Anup Patel
