Call armv7a_l1_d_cache_flush_virt() before writing the breakpoint, to make sure the d-cache is clean and invalid at the breakpoint location down to PoC. Call armv7a_l1_d_cache_inval_virt() after writing the breakpoint again, so that d-cache will pick up the modified code. Call armv7a_l1_i_cache_inval_virt() after writing the breakpoint to memory to make the change visible to the CPU.
