platform: sifive: fu540: Add 32-bit specific fdt/payload addresses

2020-02-19T11:22:07Z

For testing 32-bit SiFive specific drivers with QEMU riscv32, add 32-bit specific FW_JUMP_FDT_ADDR and FW_PAYLOAD_OFFSET. Signed-off-by: Bin Meng Reviewed-by: Anup Patel

platform: sifive: fu540: Add platform specific 'make run' cmd

platform: sifive/fu540: Set tlb range flush limit to zero

2020-02-05T05:16:29Z

It was reported that tlb range flush is not working on fu540. Only tlb full flush seems to work on fu540 probably due to some hardware errata. Set the tlb flush limit to zero so that all tlb flush requests are converted to full flush. Signed-off-by: Atish Patra Reviewed-by: Anup Patel

lib: utils: Support CLINT with 32bit MMIO access on RV64 system

2020-01-02T03:44:36Z

It is possible to have a CLINT implementation which supports only 32bit MMIO accesses on RV64 system so this patch extends our CLINT driver such that platform code can specify whether CLINT supports 64bit MMIO access. Signed-off-by: Anup Patel Reviewed-by: Atish Patra Reviewed-by: Zong Li

platform: Remove the ipi_sync method from all platforms.

2019-08-16T03:12:58Z

OpenSBI manages outstanding TLB flush requests by queueing them in a fifo synchronously. An ipi sync which uses an atomic operation on MMIO address is no longer required. Remove the ipi sync method from platform header and all usage. Signed-off-by: Atish Patra Reviewed-by: Anup Patel

platform: sifive: fu540: Expand FDT size before any patching

2019-08-09T07:00:06Z

We should expand the FDT size before any patching, otherwise it's possible the "status" fix up might fail due to insufficient space. Signed-off-by: Bin Meng Reviewed-by: Anup Patel

platform: sifive/fu540: Move FDT further up

2019-07-24T03:54:28Z

This patch changes FW_xyz_FDT_ADDR to RAM_START+128MB (i.e. 0x88000000) so that next stage bootloader (i.e. U-Boot) has enough space to unpack bigger kernel images.

platform: sifive: fu540: Use standard value string for cpu node status

2019-07-22T05:44:05Z

Per device tree spec, the standard value string for the "status" property of a cpu node is either "okay" or "disabled". "masked" was once used but it is unfortunately a spec violation. Signed-off-by: Bin Meng Acked-by: Anup Patel

platform: Remove the HiFive Unleashed expansion board DT.

2019-07-02T04:46:00Z

The Linux kernel will maintain the device tree (DT) for HiFive Unleashed from release v5.2-rc6. This DT is incompatible with previous DT present for Microsemi expansion board in OpenSBI. Since, OpenSBI will directly load the pre-built DTB from kernel now onwards, no need to keep the out-of-date DT in openSBI. Remove this DT and it's related documentation.
