An embedded open source project, such as DietPi, reads the hardware name to run different features. $ cat /proc/cpuinfo | grep Hardware Hardware : ODROID-XU4 Signed-off-by: Dongjin Kim --- arch/arm/mach-exynos/exynos.c | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) diff --git a/arch/arm/mach-exynos/exynos.c b/arch/arm/mach-exynos/exynos.c index c404c15ad07f..6197dbf9f48b 100644 --- a/arch/arm/mach-exynos/exynos.c +++ b/arch/arm/mach-exynos/exynos.c @@ -241,3 +241,31 @@ DT_MACHINE_START(EXYNOS_DT, "SAMSUNG EXYNOS (Flattened Device Tree)") .dt_compat = exynos_dt_compat, .dt_fixup = exynos_dt_fixup, MACHINE_END + +#define ODROID_MACHINE_START(name, compat) \ + DT_MACHINE_START(EXYNOS5422_ODROID_##name, "ODROID-"#name) \ + .l2c_aux_val = 0x3c400001, \ + .l2c_aux_mask = 0xc20fffff, \ + .smp = smp_ops(exynos_smp_ops), \ + .map_io = exynos_init_io, \ + .init_early = exynos_firmware_init, \ + .init_irq = exynos_init_irq, \ + .init_machine = exynos_dt_machine_init, \ + .init_late = exynos_init_late, \ + .dt_compat = compat, \ + .dt_fixup = exynos_dt_fixup, \ + MACHINE_END + +static char const *const exynos5422_odroidxu3_dt_compat[] __initconst = { + "hardkernel,odroid-xu3", + "hardkernel,odroid-xu3-lite", + NULL, +}; + +static char const *const exynos5422_odroidxu4_dt_compat[] __initconst = { + "hardkernel,odroid-xu4", + NULL, +}; + +ODROID_MACHINE_START(XU3, exynos5422_odroidxu3_dt_compat) +ODROID_MACHINE_START(XU4, exynos5422_odroidxu4_dt_compat) -- 2.11.0
