Currently the {set,get}_pull callbacks of the s3c24xx_gpiocfg_default structure
are initalized via s3c_gpio_{get,set}pull_1up. This results in a linker
error when only CONFIG_CPU_S3C2442 is selected:
arch/arm/plat-s3c24xx/built-in.o:(.data+0x13f4): undefined reference to
`s3c_gpio_getpull_1up'
arch/arm/plat-s3c24xx/built-in.o:(.data+0x13f8): undefined reference to
`s3c_gpio_setpull_1up'
The s3c2442 has pulldowns instead of pullups compared to the s3c2440.
The method of controlling them is the same though.
So this patch modifies the existing s3c_gpio_{get,set}pull_1up helper functions
to take an additional parameter deciding whether the pin has a pullup or pulldown.
The s3c_gpio_{get,set}pull_1{down,up} functions then wrap that functions passing
either S3C_GPIO_PULL_UP or S3C_GPIO_PULL_DOWN.
Furthermore this patch sets up the s3c24xx_gpiocfg_default.{get,set}_pull fields
in the s3c244{0,2}_map_io function to the new pulldown helper functions.
Based on patch from "Lars-Peter Clausen" <lars@metafoo.de>

Add the necessary gpio configuration helper for the devices which
have a single-bit pull-up resistor disabled.

Merge these two headers into one, these two SoCs are so similar.
Note, correct fault in mach-smdk2443.h including the wrong header.

First move of items out of include/asm-arm/plat-s3c* to their
new homes under arch/arm/plat-s3c/include/plat and
arch/arm/plat-s3c24xx/include/plat directories.
Note, we have to create a dummy arch/arm/plat-s3c/Makefile to
allow us to add arch/arm/plat-s3c/include/plat to the path.

This just leaves include/asm-arm/plat-* to deal with.

Remove includes of asm/hardware.h in addition to asm/arch/hardware.h.
Then, since asm/hardware.h only exists to include asm/arch/hardware.h,
update everything to directly include asm/arch/hardware.h and remove
asm/hardware.h.

The following patch and script moves the arch/arm/mach-s3c2410
directory into arch/arm/plat-s3c24xx for the generic core code
and inti arch/arm/mach-s3c{cpu} for the cpu/machine support files
Include directory include/asm-arm/plat-s3c24xx is added for the
core include files.
