| ChromeOS Firmware |
| |
| This node specifies information of ChromeOS verified-boot firmware. The |
| firmware might update this node prior to booting the kernel. |
| |
| Required properties: |
| |
| - write-protect-gpio : Describe the write-protect GPIO of the system. |
| - nonvolatile-context-storage : Storage device type that firmware used for |
| vboot nonvolatile context. It should be one of "disk", "cros-ec", or |
| "nvram". Kernel should look for the device that firmware actually used in |
| the corresponding optional property below. |
| |
| Optional properties: |
| |
| - recovery-switch : Describe the recovery switch GPIO of the system. |
| - developer-switch : Describe the developer switch GPIO of the system. |
| |
| Example: |
| |
| firmware { |
| chromeos { |
| write-protect-gpio = <&gpd1 6 0 0x10000 0>; |
| nonvolatile-context-storage = "disk"; |
| chromeos-vbc-blk = <&mshc_0 0 0 16>; |
| }; |
| }; |
| |
| Example: |
| |
| firmware { |
| chromeos { |
| pinctrl-0 = <&fw_pins>; |
| pinctrl-names = "default"; |
| write-protect-gpio = <&qcom_pinmux 17 1>; |
| recovery-switch = <&qcom_pinmux 16 1>; |
| developer-switch = <&qcom_pinmux 15 1>; |
| }; |
| }; |
