comment "FASTBOOT" menuconfig FASTBOOT bool "Fastboot support" depends on USB_GADGET default y if ARCH_SUNXI && USB_MUSB_GADGET if FASTBOOT config USB_FUNCTION_FASTBOOT bool "Enable USB fastboot gadget" default y select USB_GADGET_DOWNLOAD imply ANDROID_BOOT_IMAGE imply CMD_FASTBOOT help This enables the USB part of the fastboot gadget. config CMD_FASTBOOT bool "Enable FASTBOOT command" help This enables the command "fastboot" which enables the Android fastboot mode for the platform's USB device. Fastboot is a USB protocol for downloading images, flashing and device control used on Android devices. See doc/README.android-fastboot for more information. if USB_FUNCTION_FASTBOOT config FASTBOOT_BUF_ADDR hex "Define FASTBOOT buffer address" default 0x82000000 if MX6SX || MX6SL || MX6UL || MX6SLL default 0x81000000 if ARCH_OMAP2PLUS default 0x42000000 if ARCH_SUNXI && !MACH_SUN9I default 0x22000000 if ARCH_SUNXI && MACH_SUN9I default 0x60800800 if ROCKCHIP_RK3036 || ROCKCHIP_RK3188 || \ ROCKCHIP_RK322X default 0x800800 if ROCKCHIP_RK3288 || ROCKCHIP_RK3329 || \ ROCKCHIP_RK3399 default 0x280000 if ROCKCHIP_RK3368 default 0x100000 if ARCH_ZYNQMP help The fastboot protocol requires a large memory buffer for downloads. Define this to the starting RAM address to use for downloaded images. config FASTBOOT_BUF_SIZE hex "Define FASTBOOT buffer size" default 0x8000000 if ARCH_ROCKCHIP default 0x6000000 if ARCH_ZYNQMP default 0x2000000 if ARCH_SUNXI default 0x7000000 help The fastboot protocol requires a large memory buffer for downloads. This buffer should be as large as possible for a platform. Define this to the size available RAM for fastboot. config FASTBOOT_USB_DEV int "USB controller number" default 0 help Some boards have USB OTG controller other than 0. Define this option so it can be used in compiled environment (e.g. in CONFIG_BOOTCOMMAND). config FASTBOOT_FLASH bool "Enable FASTBOOT FLASH command" default y if ARCH_SUNXI help The fastboot protocol includes a "flash" command for writing the downloaded image to a non-volatile storage device.

Define this to the NAND device that fastboot should use to store the image. config FASTBOOT_GPT_NAME string "Target name for updating GPT" depends on FASTBOOT_FLASH default "gpt" help The fastboot "flash" command supports writing the downloaded image to the Protective MBR and the Primary GUID Partition Table. (Additionally, this downloaded image is post-processed to generate and write the Backup GUID Partition Table.) This occurs when the specified "partition name" on the "fastboot flash" command line matches the value defined here. The default target name for updating GPT is "gpt". config FASTBOOT_MBR_NAME string "Target name for updating MBR" depends on FASTBOOT_FLASH default "mbr" help The fastboot "flash" command allows to write the downloaded image to the Master Boot Record. This occurs when the "partition name" specified on the "fastboot flash" command line matches the value defined here. The default target name for updating MBR is "mbr". endif # USB_FUNCTION_FASTBOOT endif # FASTBOOT
