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 MMU v3 support

2013-05-09T08:07:09+00:00

MMUv3 comes out of reset with identity vaddr -> paddr mapping in the TLB
way 6:

This patch adds remapping code at the reset vector or at the kernel
_start (depending on CONFIG_INITIALIZE_XTENSA_MMU_INSIDE_VMLINUX) that
reconfigures MMUv3 as MMUv2:

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.
