ARM: 8323/1: force linker to use PIC veneers
When building a very large kernel, it is up to the linker to decide
when and where to insert stubs to allow calls to functions that are
out of range for the ordinary b/bl instructions.
However, since the kernel is built as a position dependent binary,
these stubs (aka veneers) may contain absolute addresses, which will
break far calls performed with the MMU off.
For instance, the call from __enable_mmu() in the .head.text section
to __turn_mmu_on() in the .idmap.text section may be turned into
something like this:
c0008168 <__enable_mmu>:
c0008168: f020 0002 bic.w r0, r0, #2
c000816c: f420 5080 bic.w r0, r0, #4096
c0008170: f000 b846 b.w c0008200 <____turn_mmu_on_veneer>
[...]
c0008200 <____turn_mmu_on_veneer>:
c0008200: 4778 bx pc
c0008202: 46c0 nop
c0008204: e59fc000 ldr ip, [pc]
c0008208: e12fff1c bx ip
c000820c: c13dfae1 teqgt sp, r1, ror #21
[...]
c13dfae0 <__turn_mmu_on>:
c13dfae0: 4600 mov r0, r0
[...]
After adding --pic-veneer to the LDFLAGS, the veneer is emitted like
this instead:
c0008200 <____turn_mmu_on_veneer>:
c0008200: 4778 bx pc
c0008202: 46c0 nop
c0008204: e59fc004 ldr ip, [pc, #4]
c0008208: e08fc00c add ip, pc, ip
c000820c: e12fff1c bx ip
c0008210: 013d7d31 teqeq sp, r1, lsr sp
c0008214: 00000000 andeq r0, r0, r0
Note that this particular example is best addressed by moving
.head.text and .idmap.text closer together, but this issue could
potentially affect any code that needs to execute with the
MMU off.

ARM: initial multiplatform support
This lets us build a multiplatform kernel for experimental purposes.
However, it will not be useful for any real work, because it relies
on a number of useful things to be disabled for now:
* SMP support must be turned off because of conflicting symbols.
Marc Zyngier has proposed a solution by adding a new SOC
operations structure to hold indirect function pointers
for these, but that work is currently stalled
* We turn on SPARSE_IRQ unconditionally, which is not supported
on most platforms. Each of them is currently in a different
state, but most are being worked on.
* A common clock framework is in place since v3.4 but not yet
being used. Work on this is on its way.
* DEBUG_LL for early debugging is currently disabled.
* THUMB2_KERNEL does not work with allyesconfig because the
kernel gets too big
[Rob Herring]: Rebased to not be dependent on the mass mach header rename.
As a result, omap2plus, imx, mxs and ux500 are not converted. Highbank,
picoxcell, mvebu, and socfpga are converted.

ARM: initial multiplatform support
This lets us build a multiplatform kernel for experimental purposes.
However, it will not be useful for any real work, because it relies
on a number of useful things to be disabled for now:
* SMP support must be turned off because of conflicting symbols.
Marc Zyngier has proposed a solution by adding a new SOC
operations structure to hold indirect function pointers
for these, but that work is currently stalled
* We turn on SPARSE_IRQ unconditionally, which is not supported
on most platforms. Each of them is currently in a different
state, but most are being worked on.
* A common clock framework is in place since v3.4 but not yet
being used. Work on this is on its way.
* DEBUG_LL for early debugging is currently disabled.
* THUMB2_KERNEL does not work with allyesconfig because the
kernel gets too big

ARM: initial multiplatform support
This lets us build a multiplatform kernel for experimental purposes.
However, it will not be useful for any real work, because it relies
on a number of useful things to be disabled for now:
* SMP support must be turned off because of conflicting symbols.
Marc Zyngier has proposed a solution by adding a new SOC
operations structure to hold indirect function pointers
for these, but that work is currently stalled
* We turn on SPARSE_IRQ unconditionally, which is not supported
on most platforms. Each of them is currently in a different
state, but most are being worked on.
* A common clock framework is in place since v3.4 but not yet
being used. Work on this is on its way.
* DEBUG_LL for early debugging is currently disabled.
* THUMB2_KERNEL does not work with allyesconfig because the
kernel gets too big
[Rob Herring]: Rebased to not be dependent on the mass mach header rename.
As a result, omap2plus, imx, mxs and ux500 are not converted. Highbank,
picoxcell, mvebu, and socfpga are converted.

ARM: 8418/1: add boot image dependencies to not generate invalid images
U-Boot is often used to boot the kernel on ARM boards, but uImage
is not built by "make all", so we are often inclined to do
"make all uImage" to generate DTBs, modules and uImage in a single
command, but we should notice a pitfall behind it. In fact,
"make all uImage" could generate an invalid uImage if it is run with
the parallel option (-j).
You can reproduce this problem with the following procedure:
[1] First, build "all" and "uImage" separately.
You will get a valid uImage
$ git clean -f -x -d
$ export CROSS_COMPILE=<your-tools-prefix>
$ make -s -j8 ARCH=arm multi_v7_defconfig
$ make -s -j8 ARCH=arm all
$ make -j8 ARCH=arm UIMAGE_LOADADDR=0x80208000 uImage

Please notice the uImage is extremely small when this issue is
encountered. Besides, "Kernel: arch/arm/boot/zImage is ready" is
displayed twice, before and after the uImage log.
The root cause of this is the race condition between zImage and
uImage. Actually, uImage depends on zImage, but the dependency
between the two is only described in arch/arm/boot/Makefile.
Because arch/arm/boot/Makefile is not included from the top-level
Makefile, it cannot know the dependency between zImage and uImage.
Consequently, when we run make with the parallel option, Kbuild
updates vmlinux first, and then two different threads descends into
the arch/arm/boot/Makefile almost at the same time, one for updating
zImage and the other for uImage. While one thread is re-generating
zImage, the other also tries to update zImage before creating uImage
on top of that. zImage is overwritten by the slower thread and then
uImage is created based on the half-written zImage.
This is the reason why "Kernel: arch/arm/boot/zImage is ready" is
displayed twice, and a broken uImage is created.
The same problem could happen on bootpImage.
This commit adds dependencies among Image, zImage, uImage, and
bootpImage to arch/arm/Makefile, which is included from the
top-level Makefile.
