platform: Add an platform ops to return platform specific tlb flush limit

2020-02-05T05:07:11Z

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 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

lib: provide a platform specific tlb range flush threshold

2019-09-10T12:14:10Z

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.

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
