sh-linux-gnu-ld:--defsym 'jiffies=jiffies_64': ignoring invalid character `'' in expression

For some reason ld has recently started complaining about the quotes, so just
get rid of them, we don't need them for anything anyways.

Same code. Use the generic version. The special Makefile treatment is
pointless anyway as init_task.o contains only data which is handled by
the linker script. So no point on being treated like head text.

This implements basic -fstack-protector support, based on the early ARM
version in c743f380. The SMP case is
limited to the initial canary value, while the UP case handles per-task
granularity (limited to 32-bit sh until a new enough sh64 compiler
manifests itself).

This takes a bit of a sledgehammer to the horribly CPU subtype
ifdef-ridden header and abstracts all of the different register layouts
in to distinct types which in turn can be overriden on a per-port basis,
or permitted to default to the map matching the port type at probe time.

In the process this ultimately fixes up inumerable bugs with mismatches
on various CPU types (particularly the legacy ones that were obviously
broken years ago and no one noticed) and provides a more tightly coupled
and consolidated platform for extending and implementing generic
features.

This code has been untouched since it was merged many years ago, and has
severely bitrotted since, suggesting that the board has no real users
left. Notice of intent to remove has been sent out over the last few
years, with no takers. Kill it off.

Nothing is using this, kill it off. Fixing up access sizes can be done
with trapped I/O for anyone wanting to make use of this for devices that

This stubs in some preliminary board support for the RTE SDK7786.

This is quite stunted at the moment, and primarily builds on top of the
system FPGA. FPGA IRQs are handled via CPU IRL masking for simplicity,
with initial peripheral support restricted to the debug ethernet.

This is a first cut at a generic DWARF unwinder for the kernel. It's
still lacking DWARF64 support and the DWARF expression support hasn't
been tested very well but it is generating proper stacktraces on SH for

This patch contains support for the romImage build target V2.

The resulting romImage file should be burned to rom
or flash and could be used as small boot loader.

Board code should keep their setup code in the file
romimage.h located in their mach include directory.

This was removed in the libgcc integration, but there are still some
compilers that need this. We also relax the rules on the ISA tuning in
the cases where there are no matches for the CPU tuning and adopt the
-any default, which matches the intent of the isa-y target list. This
compensates for mismatches where binutils supports a wide array of
targets whilst the compiler is much more restricted.
