The Arndale board is based on samsung's exynos5250 SOC.
First patch just removes the redundant SPI configs from common exynos5250
config file. Second patch moves the board specific configs to board specific
config file. The third adds the andale board support.
This patchset depends on [1] for tzpc initialization, on [2] for copying
u-boot to RAM from spl, and on first 6 patches of [3] for mmc support.

[2] http://comments.gmane.org/gmane.comp.boot-loaders.u-boot/156272

They have been defined once already. Hence remove the redundant definitions.

Not all boards based on exynos5250 have SPI flash, same serial port and might
not require the same lds script. Hence move them to board specific config file

Hi Inderpal Singh,
I observed even this defined twice can you please remove the same also
in your patch.
/* PMIC */
#define CONFIG_POWER
#define CONFIG_POWER_I2C
#define CONFIG_POWER_MAX77686
Regards,

I had thought about it, in fact I had sent a patch few days back to
use the same folder as smdk5250.
But, there could be few board specific things like gpios etc which I
think should be done in board specific folder.
Hence this approach.
Thanks,
Inder
