This defconfig already enables DEBUG_LL and by default DEBUG_LL_UART_NONE
will be selected (but due to some back compability magic I'd like to
remove is not actually honoured). DEBUG_LL_UART_PL01X is a much saner
default.

ARM: versatile: Enable DEBUG_LL_UART_PL01X

ARM: Conceal DEBUG_LL_UART_NONE from unsupported platforms
arm: Seperate DEBUG_UART_PHYS from DEBUG_LL on EP93XX
arm: Fix DEBUG_LL for multi-platform kernels (without PL01X)

Currently kiosk mode must be explicitly requested by the bootloader or
userspace. It is convenient to be able to change the default value in a
similar manner to CONFIG_MAGIC_SYSRQ_DEFAULT_MASK.

Since we now treat KDB_REPEAT_* as flags, there is no need to
pass KDB_REPEAT_NONE. It's just the default behaviour when no
flags are specified.

The actual values of KDB_REPEAT_* enum values and overall logic stayed
the same, but we now treat the values as flags.
This makes it possible to add other flags and combine them, plus makes
the code a lot simpler and shorter. But
From: Anton Vorontsov anton.voront...@linaro.org
The struct member is never used in the code, so we can remove it.
We will introduce real flags soon by renaming cmd_repeat to cmd_flags.

We're about to add more options for commands behaviour, so let's give
a more generic name to the low-level kdb command registration function.
There are just various renames, no functional changes.

So far we just do various renames, there should be no functional changes.
