2020-03-31security/vboot: relocate and rename vboot_platform_is_resuming()Bill XIE
After measured boot is decoupled from verified boot in CB:35077, vboot_platform_is_resuming() is never vboot-specific, thus it is renamed to platform_is_resuming() and declared in bootmode.h.

2020-03-17src (minus soc and mainboard): Remove copyright noticesPatrick Georgi
They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

The CBFS master header is a legacy structure that just conveys the same information we already have from the FMAP these days. We're still including it to support older CBFS implementations in some payloads, but there's no need for coreboot itself to follow this indirection anymore. This patch simplifies the default CBFS locator to just return the CBFS offset and size from the FMAP directly.
