Let all the archs that implement devmem_is_allowed() opt-in to a common definition of CONFIG_STRICT_DEVM in lib/Kconfig.debug.

Write kernel log output directly into the ocd or to a serial port.
|
|
|
|
This is useful for kernel debugging when your machine crashes very
|
|
early before the console code is initialized. For normal operation
|
|
it is not recommended because it looks ugly and doesn't cooperate
|
|
with klogd/syslogd or the X server. You should normally N here,
|
|
unless you want to debug such a crash.

Say Y here to include definitions of printascii, printch, printhex
|
|
in the kernel. This is helpful if you are debugging code that
|
|
executes before the console is initialized.

Say Y here if you want the debug print routines to direct their
|
|
output to the UniCore On-Chip-Debugger channel using CP #1.
