When aligning malloc()ed screen_base, invalid offset was added.
This not only caused misaligned result (which did not cause hardware
misbehaviour), but - worse - caused screen_base + smem_len to
be out of malloc()ed space, which in turn caused breakage of
futher malloc()/free() operation.
This patch fixes screen_base alignment.
Also this patch makes memset() that cleans framebuffer to be executed
on first initialization of diu, not only on re-initialization. It looks
correct to clean the framebuffer instead of displaying random garbage;
I believe that was disabled only because that memset caused breakage
of malloc/free described above - which no longer happens with the fix
described above.

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).
Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

Convert the board/freescale/common/Makefile to use
CONFIG_* options to select which files to conditionally
compile into the board/freescale/common library rather
than conditionally compiling entire files.
Now handles::
CONFIG_FSL_PIXIS
CONFIG_FSL_DIU_FB
CONFIG_PQ_MDS_PIB
CONFIG_ID_EEPROM is introduced until CFG_ID_EEPROM is gone.

These two structures are still needed during the
initialization and setup of the DIU hardware.
So move them to the fsl_diu_fb.h file for now.
Official "blah".

1280x1024 and 1024x768 @ 32 bpp are supported now.
DVI, Single-link LVDS, Double-link LVDS are all supported.
Environmental variable "monitor" is used to specify monitor port.
A new command "diufb" is introduced to reinitialize monitor
and display a BMP file in the memory. So far, 1-bit, 4-bit,
8-bit and 24-bit BMP formats are supported.
diufb init
- initialize the diu driver
Enable the port specified in the environmental variable "monitor"
diufb addr
- display bmp file in memory.
The bmp image should be no bigger than the resolution, 1280x1024
for DVI and double-link LVDS, 1024x768 for single-link LVDS.
Note, this driver allocate memory but doesn't free it after use
It is written on purpose -- to avoid a failure of reallocation
due to memory fragement.
ECC of DDR is disabled for DIU performance. L2 data cache is also disabled.
