This RISC-V ACLINT specification [1] defines a set of memory mapped devices which provide inter-processor interrupts (IPI) and timer functionalities for each HART on a multi-HART RISC-V platform.

This seriesl updates U-Boot existing SiFive CLINT driver to handle the ACLINT changes, and is now able to support both CLINT and ACLINT.

With this series, U-Boot is able to boot on:

- QEMU 'virt' machine with 'aclint=on' - Rocket Chip with ACLINT changes [2]

New subject: [PATCH 1/3] riscv: timer: Update the sifive clint timer driver to support aclint

This RISC-V ACLINT specification [1] defines a set of memory mapped devices which provide inter-processor interrupts (IPI) and timer functionalities for each HART on a multi-HART RISC-V platform.

The RISC-V ACLINT specification is defined to be backward compatible with the SiFive CLINT specification, however the device tree binding is a new one. This change updates the sifive clint timer driver to support ACLINT mtimer device, using a per-driver data field to hold the mtimer offset to the base address encoded in the mtimer node.

New subject: [PATCH 2/3] riscv: clint: Update the sifive clint ipi driver to support aclint

This RISC-V ACLINT specification [1] defines a set of memory mapped devices which provide inter-processor interrupts (IPI) and timer functionalities for each HART on a multi-HART RISC-V platform.

The RISC-V ACLINT specification is defined to be backward compatible with the SiFive CLINT specification, however the device tree binding is a new one. This change updates the sifive clint ipi driver to support ACLINT mswi device, by checking the per-driver data field of the ACLINT mtimer driver to determine whether a syscon based approach needs to be taken to get the base address of the ACLINT mswi device.
