xtensa: enable building of all dtbs

2015-10-27T21:12:16+00:00

Enable building all dtb files when CONFIG_OF_ALL_DTBS is enabled. The dtbs
are not really dependent on a platform being enabled or any other kernel
config, so for testing coverage it is convenient to build all of the dtbs.
This builds all dts files in the tree, not just targets listed.

xtensa: remove s6000 variant and s6105 platform

2014-10-21T09:29:01+00:00

The Stretch s6000 family support has been merged into mainline 5 years
ago. There appear to be no users of this code since nobody complained
that there is a merge error preventing compilation.

Apart from the s6105 IP camera reference design there are no s6000 devices
known to ever have run Linux and as the chips are out of production there
probably never will be. The successor s7000 no longer uses an Xtensa core
for the OS.

Let's remove the code until someone is found who actually needs it.

xtensa: simplify addition of new core variants

2014-08-14T07:59:08+00:00

Instead of adding new Kconfig options and Makefile rules for each new
core variant provide XTENSA_VARIANT_CUSTOM variant and record variant
name in the XTENSA_VARIANT_NAME variable. Adding new core variant now
means providing directory structure under arch/xtensa/variant and
specifying correct name in kernel configuration.

xtensa: don't use echo -e needlessly

2013-09-06T16:48:29+00:00

-e is not needed to output strings without escape sequences. This breaks
big endian FSF build when the shell is dash, because its builtin echo
doesn't understand '-e' switch and outputs it in the echoed string.

xtensa: add support for oprofile

2013-02-24T03:22:54+00:00

Support call graph profiling.
Keep upper two bits of PC unchanged through backtrace rather than take
them from sp (a1). The stack pointer is usually in the same GB (same
upper 2 bits) as PC, but technically doesn't always have to be (and
might not in the future, when taking full advantage of MMU v3).

xtensa: use new common dtc rule

2013-02-24T03:12:52+00:00

The current rules have the .dtb files build in a different directory
from the .dts files. This patch changes xtensa to use the generic dtb
rule which builds .dtb files in the same directory as the source .dts.

This requires moving parts of arch/xtensa/boot/Makefile into newly
created arch/xtensa/boot/dts/Makefile, and updating arch/xtensa/Makefile
to call the new Makefile.
