2021-01-07arch/x86: Move prologue to .init sectionKyösti Mälkki
For arch/x86 the realmode part has to be located within the same 64 KiB as the reset vector. Some older intel platforms also require 4 KiB alignment for _start16bit. To enforce the above, and to separate required parts of .text without matching *(.text.*) rules in linker scripts, tag the pre-C environment assembly code with section .init directive. Description of .init section for ELF: This section holds executable instructions that contribute to the process initialization code. When a program starts to run, the system arranges to execute the code in this section before calling the main program entry point (called main for C programs).

2020-03-18soc: 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.
