Newer interfaces take CONST parameters, so define CONST to minimize differences between our headers and the standards docs. r346408: Add UEFI definitions related to converting string to DEVICE_PATH Add definitions from UEFI 2.7 Errata B standards doc for converting a text string to a device path. Added clearly missing 'e' at the end of Device to resolve mismatch in that document in EFI_DEVICE_PATH_FROM_TEXT_PROTOCOL element names. r346409: Add wrapper functions to convert strings to EFI_DEVICE_PATH In anticipation of new functionality, create routines to convert char * and a CHAR16 * to a EFI_DEVICE_PATH EFI_DEVICE_PATH *efi_name_to_devpath(const char *path); EFI_DEVICE_PATH *efi_name_to_devpath16(CHAR16 *path); void efi_devpath_free(EFI_DEVICE_PATH *dp); The first two return an EFI_DEVICE_PATH for the passed in paths. The third frees up the storage the first two return when the caller is done with it. r346430: Start to reduce the number of #ifdef EFI_ZFS_BOOT There's a number of EFI_ZFS_BOOT #ifdefs that aren't needed, or can be eliminated with some trivial #defines. Remove the EFI_ZFS_BOOT ifdefs that aren't needed. Replace libzfs.h include which is not safe to include without EFI_ZFS_BOOT with efizfs.h which is and now conditionally included libzfs.h. Define efizfs_set_preferred away and define efi_zfs_probe to NULL when ZFS is compiled out. r346573: Move setting of console earlier in boot. There's no reason we can't setup the console first thing after the arch flags are setup. We set it undconditionally to efi. This is a good default, and will get us error messages to at least the efi console no matter what. This will also prime the pump so that as other variables are set, they will take effect and the console will be correct as soon as those env vars are set. Also remove the redundant setting of the console to efi when we know the console is efi. r346575: Create boot_img as a global variable Get the information from the image that we're booting and store it in a global variable. Prefer using this to passing it around. Remove the special case for zfs that set the preferred boot handle by having it uses this global variable diretly.
