ARM: berlin: switch to SPDX license identifier Use the appropriate SPDX license identifier and drop the previous boilerplate license text. Signed-off-by: Jisheng Zhang <Jisheng.Zhang@synaptics.com> 2018-05-16 15:07:52 +07:00			`/* SPDX-License-Identifier: GPL-2.0 */`
ARM: berlin: add SMP support Adds SMP support for Berlin SoCs. Secondary CPUs are reset, then execute the instruction we put in the reset exception register, setting the pc at the address contained in the software reset address register, which is the physical address of the Berlin secondary startup. This implementation avoid using the pen lock mechanism.
