Also NXP uses this\ndetection method to start their mfgr tools... Altough a hack,\nmaybe we should still add it upstream?\n\n--\nStefan\n\n\n arch/arm/include/asm/arch-mx6/imx-regs.h | 7 +++++++\n 1 file changed, 7 insertions(+)", "diff": "diff --git a/arch/arm/include/asm/arch-mx6/imx-regs.h b/arch/arm/include/asm/arch-mx6/imx-regs.h\nindex 86e267087a..895ef4de83 100644\n--- a/arch/arm/include/asm/arch-mx6/imx-regs.h\n+++ b/arch/arm/include/asm/arch-mx6/imx-regs.h\n@@ -985,5 +985,12 @@ struct pwm_regs {\n \tu32\tpr;\n \tu32\tcnr;\n };\n+\n+/*\n+ * If ROM fell back to USB recover mode, USBPH0_PWD will be clear to use USB\n+ * If boot from the other mode, USB0_PWD will keep reset value\n+ */\n+#define\tis_boot_from_usb(void) (!(readl(USB_PHY0_BASE_ADDR) & (1<<20)))\n+\n #endif /* __ASSEMBLER__*/\n #endif /* __ASM_ARCH_MX6_IMX_REGS_H__ */\n", "prefixes": [ "U-Boot", "v1", "1/2" ] }
