Arnd Bergmann 4d2b7d4cb4 ARM: 8532/1: uncompress: mark putc as inline
When CONFIG_DEBUG_ICEDCC is set, we don't use the platform
specific putc() function, but use icedcc_putc() instead, so
putc is unused and causes a compile time warning:

In file included from ../arch/arm/boot/compressed/misc.c:28:0:
arch/arm/mach-rpc/include/mach/uncompress.h:79:13: warning: 'putc' defined but not used [-Wunused-function]
arch/arm/mach-w90x900/include/mach/uncompress.h:30:13: warning: 'putc' defined but not used [-Wunused-function]

On most platforms, this does not happen, because putc is defined
as 'static inline' so the compiler will automatically drop it
when it's unused.

This changes the remaining seven platforms to behave the same way.

Arnd Bergmann 9d6eccb9cc ARM: davinci: remove tnetv107x support
The tnetv107x support does not compile, and seems to have been broken
for a while with nobody caring to fix it. So far everyone I asked
said it's probably dead and completely unused and will never again
be needed in a future kernel release, so let's delete it.

If someone finds a use for this code later and is able to get it
to work again, we can always revert the removal.

Shawn Guo b632a30e8b ARM: remove unused arch_decomp_wdog()
With ARCH_HAS_DECOMP_WDOG removed from arch/arm/boot/compressed/decompress.c,
all the arch_decomp_wdog() definition at platform level is unneeded.
Remmove it.

Sekhar Nori 09aaf994e3 ARM: davinci: uncompress.h: bail out if uart not initialized
Bail out of UART access functions in uncompress.h if the uart
port is not setup. This will happen when booting from DT since
machine type matching does not work in this case. This may also
happen if a correct machine type is not setup by bootloader.

Uwe Kleine-König 477099f189 ARM: davinci: implement DEBUG_LL port choice
Apart from the necessity to do this change for multi-platform kernels
the previous logic depended on the zImage decompressor to write the
physical and virtual address to a magic memory location.
If the decompressor is unused or not correctly configured for the
current machid, the addruart macro was an infinite loop. Moreover
debugging the early zImage code was not possible either.

Rob Herring 6f6f6a7029 ARM: create a common IOMEM definition
Several platforms create IOMEM defines for casting to 'void __iomem *',
and other platforms are incorrectly using __io() macro for the same
purpose. This creates a common definition and removes all the platform
specific versions. Rather than try to make linux/io.h and asm/io.h
assembly safe, the assembly version of IOMEM is moved into
asm/assembler.h.

Nicolas Pitre 8ea0de4b88 ARM: zImage: remove the static qualifier from global data variables
To be able to relocate the .bss section at run time independently from
the rest of the code, we must make sure that no GOTOFF relocations are
used with .bss symbols.  This usually means that no global variables can
be marked static unless they're also const.

Let's remove the static qualifier from current offenders, or turn them
into const variables when possible.  Next commit will ensure the build
fails if one of those is reintroduced due to otherwise enforced coding
standards for the kernel.

Cyril Chemparathy dc2eb76c40 Davinci: generalized debug macros
This patch adopts a debug uart selection similar to the OMAP model.  During
the boot process, the uncompress code determines the physical and virtual base
addresses of the board-specific debug uart.  These addresses are then passed
on to the in-kernel debug macros through a small chunk of memory placed just
below the page tables (@0x80003ff8).

Sudhakar Rajashekhara 0fbc559215 davinci: Add support for DA850/OMAP-L138 EVM board
Add support for the DA850/OMAP-L138 Evaluation Module (EVM)
from TI.  The EVM has User Interface (UI) card which contains
various devices. This UI card can be connected to the base
board. Support for all the devices on the UI card and ones on
the EVM will be added in subsequent patches.

The EVM schematics are not available publicly yet; but should
be available soon.

A new defconfig for this board has been added mainly because
the DA830/OMAP-L137 defconfig forces writethrough cache mode
which is not required on DA850/OMAP-L138.

This patch has been boot tested on DA850/OMAP-L138 EVM
using ramdisk as filesystem.

The davinci pre-kernel boot code assumes that all platforms use the
same UART base address for the console.  That assumption is not longer
valid with some newer SoCs so determine the console UART base address
from the machine number passed in from bootloader.
