linux.git/arch/mips/Makefile, branch v3.14

Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus

2014-01-31T01:20:32+00:00

Pull MIPS updates from Ralf Baechle:
 "The most notable new addition inside this pull request is the support
  for MIPS's latest and greatest core called "inter/proAptiv".  The
  patch series describes this core as follows.

    "The interAptiv is a power-efficient multi-core microprocessor
     for use in system-on-chip (SoC) applications. The interAptiv combines
     a multi-threading pipeline with a coherence manager to deliver improved
     computational throughput and power efficiency. The interAptiv can
     contain one to four MIPS32R3 interAptiv cores, system level
     coherence manager with L2 cache, optional coherent I/O port,
     and optional floating point unit."

  The platform specific patches touch all 3 Broadcom families.  It adds
  support for the new Broadcom/Netlogix XLP9xx Soc, building a common
  BCM63XX SMP kernel for all BCM63XX SoCs regardless of core type/count
  and full gpio button/led descriptions for BCM47xx.

  The rest of the series are cleanups and bug fixes that are MIPS
  generic and consist largely of changes that Imgtec/MIPS had published
  in their linux-mti-3.10.git stable tree.  Random other cleanups and
  patches preparing code to be merged in 3.15"

MIPS: microMIPS: Remove unsupported compiler flag.

2014-01-23T12:02:35+00:00

Remove usage of -mno-jals compiler flag when building a pure
microMIPS kernel. The -mno-jals flag only ever existed within
Mentor toolchains. Dropping this flag allows all FSF toolchains
to work.

stackprotector: Unify the HAVE_CC_STACKPROTECTOR logic between architectures

2013-12-20T08:38:40+00:00

Instead of duplicating the CC_STACKPROTECTOR Kconfig and
Makefile logic in each architecture, switch to using
HAVE_CC_STACKPROTECTOR and keep everything in one place. This
retains the x86-specific bug verification scripts.

MIPS: Kbuild: Do not allow building vmlinuz when !ZBOOT

2013-10-29T20:24:26+00:00

When CONFIG_SYS_SUPPORTS_ZBOOT is not enabled, we will still try to
build the decompressor code in arch/mips/boot/compressed as a
dependency for producing the vmlinuz target and this will result in
the following build failure:

  OBJCOPY arch/mips/boot/compressed/vmlinux.bin
arch/mips/boot/compressed/decompress.c: In function 'decompress_kernel':
arch/mips/boot/compressed/decompress.c:105:2: error: implicit
declaration of function 'decompress'
make[1]: *** [arch/mips/boot/compressed/decompress.o] Error 1
make[1]: *** Waiting for unfinished jobs....
make: *** [vmlinuz] Error 2

This is a genuine build failure because we have no implementation for
the decompress() function body since no kernel compression method
defined in CONFIG_KERNEL_(GZIP,BZIP2...) has been enabled.

arch/mips/Makefile already guards the install target for the "vmlinuz"
binary with a proper ifdef CONFIG_SYS_SUPPORTS_ZBOOT, we now also do the
same if we attempt to do a "make vmlinuz" and show that
CONFIG_SYS_SUPPORTS_ZBOOT is not enabled.

MIPS: Add uImage build target

2013-09-03T16:00:01+00:00

Add a uImage build target for MIPS, which builds uImage.gz (a U-Boot
image of vmlinux.bin.gz), and then symlinks it to uImage. This allows
for the use of other compression algorithms in future, and is how a few
other architectures do it.

It's enabled conditionally on load-y >= 0xffffffff80000000 which
hopefully allows 64bit kernels to also work as long as the load and
entry address can be represented by the 32bit addresses in the U-Boot
image format.

MIPS: Refactor load/entry address calculations

2013-09-03T15:58:37+00:00

The vmlinux load address and entry address is calculated in multiple
places:
 - arch/mips/Makefile defines load-y from CONFIG_PHYSICAL_START (or
   defined by the platform) and passes it to
   arch/mips/boot/compressed/Makefile.
 - arch/mips/boot/compressed/Makefile calculates kernel entry using nm.
 - arch/mips/lasat/image/Makefile calculates both load and entry address
   using nm.

Lets combine these in the main Makefile and then pass them as Make
parameters to each of the three boot image Makefiles (in boot/,
boot/compressed, lasat/image/). The boot/ Makefile doesn't currently use
them, but will soon need to for U-Boot image targets.

The existing load-y definition is used in preference to calculating the
load address using nm.

MIPS: Refactor boot and boot/compressed rules

2013-09-03T15:57:50+00:00

Split out the arch/mips/boot/ and arch/mips/boot/compressed/ targets
into boot-y and bootz-y variables. This makes it slightly cleaner to add
new targets.

MIPS: initial stack protector support

2013-07-01T13:10:48+00:00

Implements basic stack protector support based on ARM version in
c743f38013aeff58ef6252601e397b5ba281c633 , with Kconfig option,
constant canary value set at boot time, and script to check if
compiler actually supports stack protector.

Tested by creating a kernel module that writes past end of char[].
