tegra: usb: Add USB support to nvidia boards

2012-03-29T06:12:49+00:00

This adds basic USB support for port 0. The other port is not supported
yet.

tegra: Move boards over to use arch-level board UART function

2011-12-24T09:23:32+00:00

Now that we can set up the UART in common tegra code, make the boards
use it.

tegra: Move clock_early_init() to arch_cpu_init()

2011-12-24T09:23:32+00:00

The clock init is not board specific, so move it into
the cpu code.

tegra: Move cpu_init_cp15() to arch_cpu_init()

2011-12-24T09:23:32+00:00

This call is more of an architecture requirement than a board
one, so move it there.

tegra2: Move tegra2_mmc_init() prototype to public header.

2011-12-24T09:23:31+00:00

tegra2_mmc_init() is implemented by the Tegra2 MMC driver. Since most of
the Tegra2-based boards will need to call it, this commit exports it in
the new public asm/arch/mmc.h header file to prevent each board from
providing its own prototype.

tegra2: Plumb in SPI/UART switch code

2011-12-24T09:23:31+00:00

On Seaboard the UART and SPI interfere with each other. This causes the UART
to receive spurious zero bytes after SPI transactions and also means that
SPI can corrupt a few output characters when it starts up if they are still
in the UART buffer.

This updates the board to use the SPI/UART switch to avoid the problem.

For now this feature is turned off since it needs changes to the NS16550
UART to operate.

tegra2: Implement SPI / UART GPIO switch

2011-12-24T09:23:31+00:00

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

tegra2: spi: Add SPI driver for Tegra2 SOC

2011-12-24T09:23:30+00:00

tegra2: Add UARTB support

2011-12-24T09:23:30+00:00

UARTB is used on some boards, so support it here.
