Sync the libgcc 32bit division and modulo operations with Linux 4.4.6 ,
commit 0d1912303e54ed1b2a371be0bba51c384dd57326 . The functions in these
four files are present in lib1funcs.S in Linux, so replace these files
with lib1funcs.S from Linux.

Since we do not support stack unwinding, instead of importing the whole
asm/unwind.h and all the baggage, this patch defines empty UNWIND() macro
in lib1funcs.S . Moreover, to make all of the functions available, define
CONFIG_AEABI , which is safe, because U-Boot is always compiled with ARM
EABI.

This patch also defines CONFIG_THUMB2_KERNEL and CONFIG_ARM_ASM_UNIFIED
which is necessary for correct build of these files both in ARM and

Import unified.h from Linux kernel 4.4.6 , commit
0d1912303e54ed1b2a371be0bba51c384dd57326 . This header file contains
macros used in libgcc functions in Linux kernel on ARM and will be
needed for the libgcc sync.

Since unified.h defines the W(instr) macro, we must drop this from
the macro from memcpy.S , otherwise this triggers a warning about
symbol redefinition. In order to keep the changes to unified.h to
the minimum, tweak arch/arm/lib/Makefile such that it defines the
CONFIG_ARM_ASM_UNIFIED macro, which places .syntax unified into all
of the assembler files. This is mandatory.

Moreover, for Thumb2 build, define CONFIG_THUMB2_KERNEL macro if and
only if Thumb2 build is enabled. This macro is checked by unified.h
and toggles between ARM and Thumb2 variant of the instructions in the
assembler source files.

Finally, this patch defines __LINUX_ARM_ARCH__=N macro based on the
new CONFIG_SYS_ARM_ARCH Kconfig option. This macro selects between
more optimal and more dense codepaths which work on armv5 and newer
and less optimal codepaths which work on armv4 and possible armv3m.
Tegra2 needs the same special handling as it does in arch/arm/Makefile
to cater for the arm720t boot core.

This reverts commit 56adbb38.

Since commit 56adbb38 ("image.h: Tighten up content using handy
CONFIG_IS_ENABLED() macro."), I found my boards fail to boot Linux
because the commit changed the logic of macros it touched.  Now,
IMAGE_ENABLE_RAMDISK_HIGH and IMAGE_BOOT_GET_CMDLINE are 0 for all
the boards.

As you can see in include/linux/kconfig.h, CONFIG_IS_ENABLE() (and
IS_ENABLED() as well) can only take a macro that is either defined
as 1 or undefined.  This is met for boolean options defined in
Kconfig.  On the other hand, CONFIG_SYS_BOOT_RAMDISK_HIGH and
CONFIG_SYS_BOOT_GET_CMDLINE are defined without any value in
arch/*/include/asm/config.h .  This kind of clean-up is welcome,
but the options should be moved to Kconfig beforehand.

Moreover, CONFIG_IS_ENABLED(SPL_CRC32_SUPPORT) looks weird.
It should be either CONFIG_IS_ENABLED(CRC32_SUPPORT) or
IS_ENABLED(CONFIG_SPL_CRC32_SUPPORT).  But, I see no define for
CONFIG_SPL_CRC32_SUPPORT anywhere.  Likewise for the other three.

The logic of IMAGE_OF_BOARD_SETUP and IMAGE_OF_SYSTEM_SETUP were
also changed for SPL.  This can be a problem for boards defining
CONFIG_SPL_OF_LIBFDT.  I guess it should have been changed to
IS_ENABLED(CONFIG_OF_BOARD_SETUP).

In the first place, if we replace the references in C code,
the macros IMAGE_* will go away.

Signed-off-by: NPaul Burton <paul.burton@imgtec.com>

Use CPHYSADDR to implement the virt_to_phys function for converting from
a virtual to a physical address for MIPS32, much as is already done for
MIPS64. This allows for virt_to_phys to work regardless of whether the
address being translated is in kseg0 or kseg1, unlike the previous
subtraction based approach which only worked for addresses in kseg0.
This allows for drivers to provide an address to virt_to_phys without
needing to manually ensure that kseg1 addresses are converted to
equivalent kseg0 addresses first.
