Subject: lib: Define autoboot_options, device_type helpers
X-Git-Tag: v1.0.0~74^2~13
X-Git-Url: http://git.ozlabs.org/?p=petitboot;a=commitdiff_plain;h=366ff957d2900eae6d26ad2f002b735302e7eb41;ds=sidebyside

lib: Define autoboot_options, device_type helpers

Add the new autoboot_option struct, and helper functions for working
with device_type enums. device_type_name() returns exact strings as used
by platform code to read/write nvram params, so
device_type_display_name() is added for use in user-visible strings.
