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.

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
