refactor(platforms): add generic hold penIntroduce a common hold pen implementation for SMP secondary CPUbring-up. Each core has a cache-line-aligned hold_slot structwhose 'entry' field holds HOLD_STATE_WAIT (all-ones sentinel)while the core should keep polling, or the warm boot entrypointaddress when it should go.plat_hold_pen_init() sets all slots to HOLD_STATE_WAIT and flushesthem to main memory. This is called once during boot toestablish a known-good state, overwriting any stale cached dataleft by earlier boot stages (e.g. a BL2 dcsw_op_all).plat_hold_pen_signal() writes the entrypoint into the target slot,flushes it, and issues SEV.The plat_hold_pen_wait_and_jump assembly macro provides thesecondary CPU polling loop for both AArch64 and AArch32.Change-Id: Id7322cb9e8caa6a750348d194b4db66e2a515623Signed-off-by: Nicolas Pitre List of files: /rk3399_ARM-atf/include/plat/common/plat_hold_pen.h
