Given * that BOOT_TARGET_DEVICES is a macro that's expanded by the C pre-processor * at compile time, it's not possible to detect and report such problems via * a simple #ifdef/#error combination. Still, the code needs to report errors. * The best way I've found to do this is to make BOOT_TARGET_DEVICES expand to * reference a non-existent symbol, and have the name of that symbol encode * the error message. Consequently, this file contains references to e.g. * BOOT_TARGET_DEVICES_references_MMC_without_CONFIG_CMD_MMC. Given the * prevalence of capitals here, this looks like a pre-processor macro and * hence seems like it should be all capitals, but it's really an error * message that includes some other pre-processor symbols in the text. */ #define BOOTENV_SHARED_BLKDEV_BODY(devtypel) \ "if " #devtypel " dev ${devnum}; then " \ "devtype=" #devtypel "; " \ "run scan_dev_for_boot_part; " \ "fi\0" #define BOOTENV_SHARED_BLKDEV(devtypel) \ #devtypel "_boot=" \ BOOTENV_SHARED_BLKDEV_BODY(devtypel) #define BOOTENV_DEV_BLKDEV(devtypeu, devtypel, instance) \ "bootcmd_" #devtypel #instance "=" \ "devnum=" #instance "; " \ "run " #devtypel "_boot\0" #define BOOTENV_DEV_NAME_BLKDEV(devtypeu, devtypel, instance) \ #devtypel #instance " " #ifdef CONFIG_SANDBOX #define BOOTENV_SHARED_HOST BOOTENV_SHARED_BLKDEV(host) #define BOOTENV_DEV_HOST BOOTENV_DEV_BLKDEV #define BOOTENV_DEV_NAME_HOST BOOTENV_DEV_NAME_BLKDEV #else #define BOOTENV_SHARED_HOST #define BOOTENV_DEV_HOST \ BOOT_TARGET_DEVICES_references_HOST_without_CONFIG_SANDBOX #define BOOTENV_DEV_NAME_HOST \ BOOT_TARGET_DEVICES_references_HOST_without_CONFIG_SANDBOX #endif #ifdef CONFIG_CMD_MMC #define BOOTENV_SHARED_MMC BOOTENV_SHARED_BLKDEV(mmc) #define BOOTENV_DEV_MMC BOOTENV_DEV_BLKDEV #define BOOTENV_DEV_NAME_MMC BOOTENV_DEV_NAME_BLKDEV #else #define BOOTENV_SHARED_MMC #define BOOTENV_DEV_MMC \ BOOT_TARGET_DEVICES_references_MMC_without_CONFIG_CMD_MMC #define BOOTENV_DEV_NAME_MMC \ BOOT_TARGET_DEVICES_references_MMC_without_CONFIG_CMD_MMC #endif #ifdef CONFIG_CMD_UBIFS #define BOOTENV_SHARED_UBIFS \ "ubifs_boot=" \ "if ubi part ${bootubipart} ${bootubioff} && " \ "ubifsmount ubi0:${bootubivol}; " \ "then " \ "devtype=ubi; " \ "devnum=ubi0; " \ "bootfstype=ubifs; " \ "distro_bootpart=${bootubivol}; " \ "run scan_dev_for_boot; " \ "ubifsumount; " \ "fi\0" #define BOOTENV_DEV_UBIFS_BOOTUBIOFF(off) #off /* type check, throw error when called with more args */ #define BOOTENV_DEV_UBIFS(devtypeu, devtypel, instance, bootubipart, bootubivol, ...) \ "bootcmd_ubifs" #instance "=" \ "bootubipart=" #bootubipart "; " \ "bootubivol=" #bootubivol "; " \ "bootubioff=" BOOTENV_DEV_UBIFS_BOOTUBIOFF(__VA_ARGS__) "; " \ "run ubifs_boot\0" #define BOOTENV_DEV_NAME_UBIFS(devtypeu, devtypel, instance, ...) \ #devtypel #instance " " #else #define BOOTENV_SHARED_UBIFS #define BOOTENV_DEV_UBIFS \ BOOT_TARGET_DEVICES_references_UBIFS_without_CONFIG_CMD_UBIFS #define BOOTENV_DEV_NAME_UBIFS \ BOOT_TARGET_DEVICES_references_UBIFS_without_CONFIG_CMD_UBIFS #endif #ifdef CONFIG_EFI_LOADER #if defined(CONFIG_ARM64) #define BOOTEFI_NAME "bootaa64.efi" #elif defined(CONFIG_ARM) #define BOOTEFI_NAME "bootarm.efi" #elif defined(CONFIG_X86_RUN_32BIT) #define BOOTEFI_NAME "bootia32.efi" #elif defined(CONFIG_X86_RUN_64BIT) #define BOOTEFI_NAME "bootx64.efi" #elif defined(CONFIG_ARCH_RV32I) #define BOOTEFI_NAME "bootriscv32.efi" #elif defined(CONFIG_ARCH_RV64I) #define BOOTEFI_NAME "bootriscv64.efi" #endif #endif #ifdef BOOTEFI_NAME #if defined(CONFIG_ARM) && !defined(CONFIG_ARM64) /* * On 32bit ARM systems there is a reasonable number of systems that follow * the $soc-$board$boardver.dtb name scheme for their device trees.
