8c770db925 microblaze: remove check for CONFIG_XILINX_CONSOLE
There's been a check for CONFIG_XILINX_CONSOLE since v2.6.30. But the
Kconfig symbol XILINX_CONSOLE was never added. Remove this check.

And, since DUMMY_CONSOLE depends on VT, we can now drop the check for
CONFIG_VT.

b0a6fb36a4 of/fdt: create common debugfs
Both powerpc and microblaze have the same FDT blob in debugfs feature.
Move this to common location and remove the powerpc and microblaze
implementations. This feature could become more useful when FDT
overlay support is added.

This changes the path of the blob from "$arch/flat-device-tree" to
"device-tree/flat-device-tree".

79c157a3fb microblaze: Rename global function heartbeat()
microblaze:allmodconfig complains for some configurations that 'heartbeat'
is redefined as different kind of symbol. This is seen in test compiles
of watchdog drivers, which often use 'heartbeat' as ststic variable.

Since 'heartbeat' is an unfortunate name for a global function,
rename it to microblaze_heartbeat. Also rename the setup function
to microblaze_setup_heartbeat.

3a36cb11ca ftrace: Do not pass data to ftrace_dyn_arch_init
As the data parameter is not really used by any ftrace_dyn_arch_init,
remove that from ftrace_dyn_arch_init. This also removes the addr
local variable from ftrace_init which is now unused.

Note the documentation was imprecise as it did not suggest to set
(*data) to 0.

af64a7cb09 ftrace: Pass retval through return in ftrace_dyn_arch_init()
No architecture uses the "data" parameter in ftrace_dyn_arch_init() in any
way, it just sets the value to 0. And this is used as a return value
in the caller -- ftrace_init, which just checks the retval against
zero.

Note there is also "return 0" in every ftrace_dyn_arch_init.  So it is
enough to check the retval and remove all the indirect sets of data on
all archs.
