wangming9 8d21bbf3be arch/armv8-m: Supports interrupt nesting between TEE and REE ... The first time interrupt nesting occurs between REE and TEE, CURRENT_REGS needs to be set. If TEE nesting REE breaks, then EXC_RETURN.S=0,EXC_RETURN.ES=1; Conversely, EXC_RETURN.S=1,EXC_RETURN.ES=0; Interrupt nesting between TEE and REE can be determined based on the S and ES bits of EXC_RETURN. Only once nesting between TEE and REE is supported, and cyclic nesting between TEE and REE is not supported. Signed-off-by: wangming9 <wangming9@xiaomi.com>		2023-08-07 05:43:13 -07:00
