Arnd Bergmann 64367f2e4f treewide: defconfig: address renamed CONFIG_DEBUG_INFO=y
CONFIG_DEBUG_INFO is now implicitly selected if one picks one of the
explicit options that could be DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT,
DEBUG_INFO_DWARF4, DEBUG_INFO_DWARF5.

This was actually not what I had in mind when I suggested making it a
'choice' statement, but it's too late to change again now, and the Kconfig
logic is more sensible in the new form.

Change any defconfig file that had CONFIG_DEBUG_INFO enabled but did not
pick DWARF4 or DWARF5 explicitly to now pick the toolchain default.

Michal Simek 05cdf45747 microblaze: Remove noMMU code
This configuration is obsolete and likely none is really using it. That's
why remove it to simplify code.

Note about CONFIG_MMU in hw_exception_handler.S is left intentionally
for better comment understanding.

Michal Simek 2602276d3d microblaze: Wire CMA allocator
Based on commit 04e3543e22 ("microblaze: use the generic dma coherent
remap allocator")
CMA can be easily enabled by calling dma_contiguous_reserve() at the end of
mmu_init(). High limit is end of lowmem space which is completely unused at
this point of time.

Linus Walleij 7cca9b8b7c microblaze: Switch to standard restart handler
The microblaze uses the legacy APIs to dig out a GPIO pin
defined in the root of the device tree to issue a hard
reset of the platform.

Asserting a hard reset should be done using the standard
DT-enabled and fully GPIO descriptor aware driver in
drivers/power/reset/gpio-restart.c using the bindings
from Documentation/devicetree/bindings/power/reset/gpio-restart.txt

To achieve this, first make sure microblaze makes use of
the standard kernel restart path utilizing do_kernel_restart()
from <linux/reboot.h>. Put in some grace time and an
emergency print if the restart does not properly assert.

As this is basic platform functionality we patch the DTS
file and defconfig in one go for a lockstep change.

David Howells 50d35015ff KEYS: CONFIG_KEYS_DEBUG_PROC_KEYS is no longer an option
CONFIG_KEYS_DEBUG_PROC_KEYS is no longer an option as /proc/keys is now
mandatory if the keyrings facility is enabled (it's used by libkeyutils in
userspace).

The defconfig references were removed with:

	perl -p -i -e 's/CONFIG_KEYS_DEBUG_PROC_KEYS=y\n//' \
	    `git grep -l CONFIG_KEYS_DEBUG_PROC_KEYS=y`

and the integrity Kconfig fixed by hand.

David Rientjes 6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.
