firmware: imx: Align imx_sc_msg_req_cpu_start to 4

2020-02-24T07:27:48+00:00

The imx SC api strongly assumes that messages are composed out of 4-bytes words but some of our message structs have odd sizeofs. This produces many oopses with CONFIG_KASAN=y. Fix by marking with __aligned(4). Fixes: d90bf296ae18 ("firmware: imx: Add support to start/stop a CPU") Signed-off-by: Leonard Crestez Signed-off-by: Shawn Guo

The imx SC api strongly assumes that messages are composed out of 4-bytes words but some of our message structs have odd sizeofs. This produces many oopses with CONFIG_KASAN=y: BUG: KASAN: stack-out-of-bounds in imx_mu_send_data+0x108/0x1f0 It shouldn't cause an issues in normal use because these structs are always allocated on the stack.
