[ Upstream commit 2370eba9f552eaae3d8aa1f70b8e9eec5c560f9e ] [Why] When some tools performing psp mailbox attack, the readback value of register can be a random value which may break psp. [How] Use a psp wptr cache machanism to aovid the change made by attack. v2: unify change and add detailed reason Signed-off-by: Victor Zhao Signed-off-by: Jingwen Chen Reviewed-by: Monk Liu Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin
