This commit changes the working directory
where the build process occurs.
Before this commit, build process occurred under the source
tree for both in-tree and out-of-tree build.
That's why we needed to add $(obj) prefix to all generated
files in makefiles like follows:
$(obj)u-boot.bin: $(obj)u-boot
Here, $(obj) is empty for in-tree build, whereas it points
to the output directory for out-of-tree build.
And our old build system changes the current working directory
with "make -C <sub-dir>" syntax when descending into the
sub-directories.
On the other hand, Kbuild uses a different idea
to handle out-of-tree build and directory descending.
The build process of Kbuild always occurs under the output tree.
When "O=dir/to/store/output/files" is given, the build system
changes the current working directory to that directory and
restarts the make.
Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>"
syntax for descending into sub-directories.
(We can write it like "make $(obj)=<sub-dir>" with a shorthand.)
This means the current working directory is always the top
of the output directory.

We have converted all makefiles needed to build $(LIBS).
Until this commit we used to grep switch so that U-Boot style
and Kbuild style makefiles coexist.
But we do not need any more.
Goint forward, use always Kbuild style Makefile when adding
a new Makefile

For Non-Nvidia boards to include newly added features (like emc clock
scaling) it would be necessary to add each feature to their own board
Makefile. This is because currently the top Makefile automaticly includes
these features only for Nvidia boards.
This patch adds a simple Makefile include so all new features become
available for non-Nvidia board vendors.

Change the mkdir commands for the object directories to be
unconditional. This fixes an issue when building for SPL where
SRCTREE and OBJTREE are the same, but $(obj) is under SPLTREE.

This commit uses the common Tegra board implementation instead of
duplicating a lot of the code. In addition, the Plutux and Medcom
specific board files can be removed as the MMC/SD setup is common
among all Tamonten-based boards.

The Medcom is a 16:9 15" terminal that is used for patient infotainment
in hospitals.
Changes in v3:
* Remove unused implementation of gpio_config_uart().
* Implement MMC/SD card detection.
* Drop board_mmc_getcd() which is now implemented by common Tegra2
code.
* Add MAINTAINERS entry.
Changes in v2:
* No longer override the default CONFIG_SYS_TEXT_BASE setting.

The Tegra2 Seaboard has the unfortunate feature that SPI and the console
UART are multiplexed on the same pins. We need to switch between one
and the other during SPI and console activity.
This new file implements a switch and keeps track of which peripheral
owns the pins. It also flips over the controlling GPIO as needed
Since we are adding a second file to board/nvidia/common, we create
a proper Makefile there and remove the direct board.o include from
board/nvidia/seaboard/Makefile

Seems people fixed their files to use libfoo.o, but didn't actually
update the creation targets to use $(cmd_link_o_target). Update the
rest of the Makefile's found with grep.

The top level Makefile does not do any recursion into subdirs when
cleaning, so these clean/distclean targets in random arch/board dirs
never get used. Punt them all.
MAKEALL didn't report any errors related to this that I could see.

The out-of-tree build fails because the Makefiles in question depend on
source files of another directory but do not explicitly mkdir that
directory.
As a matter of fact, other Makefiles under board/*/ directory that refer
to source files under another directory explicitly call mkdir.
This patch adds explicit mkdir's to the Makefiles in question, and
verifies that out-of-tree build is working.
