ARM: tegra: make all I2C ports open-drain

2014-03-26T22:20:56+00:00

I2C protocol requires open-drain IOs. Fix the Dalmore and Venice2 pinmux
tables to configure the IOs correctly. Without this, Tegra may actively
drive the lines high while an external device is actively driving the
lines low, which can only lead to bad things.

venice2: move device tree to fix build error

2014-02-20T17:00:20+00:00

Commit 5ab502cb gathered all device tree sources
to arch/$(ARCH)/dts/.
So tegra124-venice2.dts also must go to arch/arm/dts directory
to build venice2 board.

(Commit 5ab502cb had been posted before venice2 board support
was merged. So an unvisible conflict happened.)

dts: move device tree sources to arch/$(ARCH)/dts/

2014-02-19T16:10:05+00:00

Unlike Linux Kernel, U-Boot historically had *.dts files under
board/$(VENDOR)/dts/ and *.dtsi files under arch/$(ARCH)/dts/.

I think arch/$(ARCH)/dts dicretory is a better location
to store both *.dts and *.dtsi files.

For example, before this commit, board/xilinx/dts directory
had both Microblaze dts (microblaze-generic.dts) and
ARM dts (zynq-*.dts), which are totally unrelated.

This commit moves *.dts to arch/$(ARCH)/dts/ directories,
allowing us to describe nicely mutiple DTBs generation in the next commit.

kbuild: change out-of-tree build

2014-02-19T16:07:50+00:00

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 " 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="
syntax for descending into sub-directories.
(We can write it like "make $(obj)=" with a shorthand.)
This means the current working directory is always the top
of the output directory.

ARM: tegra: add Venice2 (Tegra124) board

2014-02-03T16:46:47+00:00

These are the board files for Venice2 (Tegra124), plus the AS3722 PMIC
files. PMIC init will be moved to pmic_common_init later.

This builds/boots on Venice2, SPI/MMC/USB/I2C all work. Audio, display
and WB/LP0 are not supported yet.

ARM: tegra: add DT files for Tegra124 and Venice2

2014-02-03T16:46:47+00:00

These are fairly complete, and near-clones of Tegra114 Venice, with an
additional I2C port, and MMC address changes for Tegra124.

ARM: tegra: only build __pinmux_nand() when it's needed

2014-02-03T16:46:46+00:00

__pinmux_nand() won't compile if PERIPH_ID_NDFLASH isn't defined.
Prevent this from causing build problems on newer SoCs without NAND
support (or without SW support for NAND yet), but preventing
compilation unless the function will actually be used, i.e. when
CONFIG_TEGRA_NAND is defined.

lib: time: add weak timer_init() function

2014-01-24T21:59:06+00:00

If timer_init() is made a weak stub function, then it allows us to
remove several empty timer_init functions for those boards that
already have a timer initialized when u-boot starts. Architectures
that use the timer framework may also remove the need for timer.c.

Makefile: convert makefiles to Kbuild style and delete grep switch

2013-11-01T15:42:13+00:00

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
