tegra2: Fix out-of-tree build for Ventana.

2011-12-22T07:36:09+00:00

Since Ventana is derived from Seaboard and requires seaboard.c to build,
make sure board/nvidia/seaboard is created in the build tree.

tegra2: Enable instruction cache

2011-12-09T16:30:09+00:00

Since low-level init is skipped, the instruction cache is never enabled on
Tegra2. This explicitly calls this initialization as soon as the A9 is
initialized.

tegra2: Add arch_cpu_init() to fire up Cortex-A9

2011-12-09T16:30:08+00:00

We want to move away from a special Tegra2 start-up, and just use
arch_cpu_init() instead. However, if we run board_init_f() from boot
we need to build it for ARMv4T, since the Tegra's AVP start-up CPU
does not support ARMv7.

The effect of this is to do the AVP init earlier, and in
arch_cpu_init(), rather that board_early_init_f().

tegra2: Use new GPIO APIs in gpio_config_uart()

2011-12-09T16:30:08+00:00

... rather than open-coding the register accesses.

However, gpio_request() typically stores the "label" parameter in a global
data structure. This causes problems when called from gpio_config_uart(),
since the code is running before relocation. To solve this, pass a NULL
string to gpio_request(), and modify gpio_request() not to touch the string
if it's NULL.

tegra2: Add support for Ventana

2011-12-09T16:30:08+00:00

Ventana is a board which is very similar to Seaboard. Support it by
re-using board/nvidia/seaboard/seaboard.c with minor run-time conditionals.

v5: Makefile: Use cmd_link_o_target, remove unused clean/distclean targets.
v6: Make gpio_config_uart_seaboard() static.
v7: Add MAINTAINERS entry for Ventana. Tom Warren doesn't have Ventana, so
    he asked me to add myself for this board.

tegra2: Modify MMC driver to handle power and cd GPIOs

2011-12-09T16:30:08+00:00

Pass the GPIO numbers for power and card detect to tegra2_mmc_init(), and
modify that function to perform all required GPIO initialization. This
removes the need for board files to perform these operations.

Move board_mmc_getcd() into tegra2_mmc.c now that the driver knows which
GPIOs to use.

Update affected call-sites in seaboard.c and harmony.c. Note that this
change should make all SD ports work on Harmony, since the required GPIO
setup is now being performed.

v4: Fix prototype of tegra2_mmc_init() in board.h to match driver change.
    Remove prototype of gpio_config_mmc() from board.h

tegra2: Move board_mmc_init into board files

2011-12-09T16:30:08+00:00

For Seaboard, this is mostly a cut/paste of board_mmc_init() and
pin_mux_mmc() into seaboard.c; pin_mux_mmc() was modified to add some
missing pinmux_tristate_disable calls for the GPIOs.

For Harmony, those functions were modified to configure SDMMC2 (index 2)
instead of SDMMC3 (index 1), since that's what is present on the board.

However, harmony.c is still missing the required GPIO setup, so neither
port is likely to function correctly yet.  This will be fixed in the next
change.

v4: Include board.h to prototype tegra2_mmc_init().

tegra2: Move MMC clock initialization into MMC driver

2011-11-03T07:15:00+00:00

This centralizes knowledge of MMC clocking into the MMC driver. This also
removes clock setup from the board files, which will simplify later changes
that modify the Harmony board to support the correct set of MMC controllers.

tegra2: Enable MMC for Seaboard

This adds the required GPIO and pinmux configuration to make eMMC / SD work
on Seaboard.

tegra2: Add more pinmux functions

2011-10-27T19:56:29+00:00

This adds support for changing pinmux functions of pin groups. This is done
by defining a PMUX_FUNC_... enum which can be used to select the function for
each group using pinmux_set_func(). It is also possible to enable
pullup/pulldown, and the existing tristate functionality is retained.

Also provided is a means of configuring a list of pingroups by providing a
configuration table to pinmux_config_table().
