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.

2019-12-04Change all clrsetbits_leXX() to clrsetbitsXX()Julius Werner
This patch changes all existing instances of clrsetbits_leXX() to the new endian-independent clrsetbitsXX(), after double-checking that they're all in SoC-specific code operating on CPU registers and not actually trying to make an endian conversion. This patch was created by running sed -i -e 's/\([cs][le][rt]bits\)_le\([136][624]\)/\1\2/g' across the codebase and cleaning up formatting a bit.

tlclk is not specific to the UART block in the FU540, so let's calculate its frequency in clock.c.

2018-12-04soc/sifive/fu540: Load PLL settings from a structJonathan Neuschäfer
The different PLLs in the fu540 use the same register layout, so use one function (configure_pll) to program a PLL and wait for it to lock. This also makes it possible to dynamically calculate the PLL settings later.
