2020-02-07platform: sifive: fu540: Add platform specific 'make run' cmdBin Meng1-0/+4
This adds sifive/fu540 specific QEMU run command. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Anup Patel <anup.patel@wdc.com>
2020-02-07platform: Drop qemu/sifive_u supportBin Meng3-208/+0
With QEMU v4.2 RISC-V changes to improve the emulation fidelity of 'sifive_u' machine, OpenSBI v0.4 / U-Boot v2019.10 / Linux kernel v5.3 images built for the SiFive HiFive Unleashed board can be used out of the box without any special hack. Hence there is no need for us to continue supporting such a special target in OpenSBI. Going forward, sifive/fu540 platform can be used on both real hardware and QEMU 'sifive_u' machine.

2020-02-05platform: sifive/fu540: Set tlb range flush limit to zeroAtish Patra1-0/+9
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 <atish.patra@wdc.com> Reviewed-by: Anup Patel <anup.patel@wdc.com>
2020-02-05platform: Add an platform ops to return platform specific tlb flush limitAtish Patra1-1/+0
If a platform requires to perform a tlb full flush, they should set the tlb_range_flush_limit value to zero. However, corresponding platform API ignore the value and continue to return the default value. Add a platform ops to retrieve platform specific tlb range flush limit. The platform variable becomes redundant in presence of the platform ops. Take this opportunity to remove the variable as well. The default is still set to smallest page size in RISC-V (4KB), as there is no way to figure out a best value for all platforms. Individual platform should set it to the optimal value for their platform. Signed-off-by: Atish Patra <atish.patra@wdc.com> Reviewed-by: Anup Patel <anup.patel@wdc.com>

Currently, the tlb range flush threshold is fixed and set to 4k for all platforms. However, it should be platform specific as it completely depends upon how platform actually implements sfence instruction. Define a platform feature that allows every individual platform to set different values. If a platform doesn't define it, just use a page size as the threshold.
