From 94db66557997a929313e0f5020c83368b1c6627f Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Sun, 26 Jan 2014 15:06:41 -0200 Subject: [PATCH] mx6: Distinguish mx6dual from mx6quad Currently when we boot a mx6dual U-boot reports that it is a mx6quad. Report it as MX6D instead: CPU: Freescale i.MX6D rev1.2 at 792 MHz Signed-off-by: Fabio Estevam Acked-by: Stefano babic Acked-by: Otavio Salvador --- arch/arm/cpu/armv7/mx6/soc.c | 14 +++++++++++--- arch/arm/imx-common/cpu.c | 2 ++ arch/arm/include/asm/arch-imx/cpu.h | 1 + 3 files changed, 14 insertions(+), 3 deletions(-) diff --git a/arch/arm/cpu/armv7/mx6/soc.c b/arch/arm/cpu/armv7/mx6/soc.c index 2aad0a15bb..4c5c367221 100644 --- a/arch/arm/cpu/armv7/mx6/soc.c +++ b/arch/arm/cpu/armv7/mx6/soc.c @@ -41,14 +41,19 @@ u32 get_cpu_rev(void) if (type != MXC_CPU_MX6SL) { reg = readl(&anatop->digprog); + struct scu_regs *scu = (struct scu_regs *)SCU_BASE_ADDR; + u32 cfg = readl(&scu->config) & 3; type = ((reg >> 16) & 0xff); if (type == MXC_CPU_MX6DL) { - struct scu_regs *scu = (struct scu_regs *)SCU_BASE_ADDR; - u32 cfg = readl(&scu->config) & 3; - if (!cfg) type = MXC_CPU_MX6SOLO; } + + if (type == MXC_CPU_MX6Q) { + if (cfg == 1) + type = MXC_CPU_MX6D; + } + } reg &= 0xff; /* mx6 silicon revision */ return (type << 12) | (reg + 0x10); @@ -62,6 +67,9 @@ u32 __weak get_board_rev(void) if (type == MXC_CPU_MX6SOLO) cpurev = (MXC_CPU_MX6DL) << 12 | (cpurev & 0xFFF); + if (type == MXC_CPU_MX6D) + cpurev = (MXC_CPU_MX6Q) << 12 | (cpurev & 0xFFF); + return cpurev; } #endif diff --git a/arch/arm/imx-common/cpu.c b/arch/arm/imx-common/cpu.c index 9231649409..a77c4decc9 100644 --- a/arch/arm/imx-common/cpu.c +++ b/arch/arm/imx-common/cpu.c @@ -106,6 +106,8 @@ const char *get_imx_type(u32 imxtype) switch (imxtype) { case MXC_CPU_MX6Q: return "6Q"; /* Quad-core version of the mx6 */ + case MXC_CPU_MX6D: + return "6D"; /* Dual-core version of the mx6 */ case MXC_CPU_MX6DL: return "6DL"; /* Dual Lite version of the mx6 */ case MXC_CPU_MX6SOLO: diff --git a/arch/arm/include/asm/arch-imx/cpu.h b/arch/arm/include/asm/arch-imx/cpu.h index 8c725e2362..a35940e64f 100644 --- a/arch/arm/include/asm/arch-imx/cpu.h +++ b/arch/arm/include/asm/arch-imx/cpu.h @@ -10,3 +10,4 @@ #define MXC_CPU_MX6DL 0x61 #define MXC_CPU_MX6SOLO 0x62 #define MXC_CPU_MX6Q 0x63 +#define MXC_CPU_MX6D 0x64 -- 2.39.2
