As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

/* One-letter commands for code not meant to be ready for humans.
|
|
* The code was generated by a set of programs/scripts.
|
|
* M print out a kernel message
|
|
* R read a register. We do these mainly to ensure that if hardware wanted
|
|
* the register read, it was read; also, in debug, we can see what was expected
|
|
* and what was found. This has proven *very* useful to get this debugged.
|
|
* The udelay, if non-zero, will make sure there is a
|
|
* udelay() call with the value.
|
|
* The count is from the kernel and tells us how many times this read was done.
|
|
* Also useful for debugging and the state
|
|
* machine uses the info to drive a poll.
|
|
* W Write a register
|
|
* V set verbosity. It's a bit mask.
|
|
* 0 -> nothing
|
|
* 1 -> print kernel messages
|
|
* 2 -> print IO ops
|
|
* 4 -> print the number of times we spin on a register in a poll
|
|
* 8 -> restore whatever the previous verbosity level was
|
|
* (only one deep stack)
|
|
*
|
|
* Again, this is not really meant for human consumption. There is not a poll
|
|
* operator as such because, sometimes, there is a read/write/read where the
|
|
* second read is a poll, and this chipset is so touchy I'm reluctant to move
|
|
* things around and/or delete too many reads.
