Tomasz Figa 7366b92a77 ARM: Add interface for registering and calling firmware-specific operations ... Some boards are running with secure firmware running in TrustZone secure world, which changes the way some things have to be initialized. This patch adds an interface for platforms to specify available firmware operations and call them. A wrapper macro, call_firmware_op(), checks if the operation is provided and calls it if so, otherwise returns -ENOSYS to allow fallback to legacy operation.. By default no operations are provided. Example of use: In code using firmware ops: __raw_writel(virt_to_phys(exynos4_secondary_startup), CPU1_BOOT_REG); /* Call Exynos specific smc call */ if (call_firmware_op(cpu_boot, cpu) == -ENOSYS) cpu_boot_legacy(...); /* Try legacy way */ gic_raise_softirq(cpumask_of(cpu), 1); In board-/platform-specific code: static int platformX_do_idle(void) { /* tell platformX firmware to enter idle */ return 0; } static int platformX_cpu_boot(int i) { /* tell platformX firmware to boot CPU i */ return 0; } static const struct firmware_ops platformX_firmware_ops = { .do_idle = exynos_do_idle, .cpu_boot = exynos_cpu_boot, /* other operations not available on platformX */ }; static void __init board_init_early(void) { register_firmware_ops(&platformX_firmware_ops); } Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: Tomasz Figa <t.figa@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>		2013-04-09 01:52:06 +09:00
