* tegra2: Move tegra2_mmc_init() prototype to public header.Thierry Reding2011-12-24-1/+1
| | | | | | | | | | | | | 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 codeSimon Glass2011-12-24-0/+3
| | | | | | | | | | | | | | | 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 switchSimon Glass2011-12-24-1/+0
| | | | | | | | | | | | | | | | 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 Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
* tegra2: Use new GPIO APIs in gpio_config_uart()Stephen Warren2011-12-09-16/+2
| | | | | | | | | | | | | | | ... 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 VentanaStephen Warren2011-12-09-2/+9
| | | | | | | | | | | | | | 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 GPIOsStephen Warren2011-12-09-31/+2
| | | | | | | | | | | | | | | | | | | | | | | 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.

* tegra2: Move board_mmc_init into board filesStephen Warren2011-12-09-0/+53
| | | | | | | | | | | | | | | | | | | | 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().

| | | | | | | | | 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. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Tested-by: Simon Glass <sjg@chromium.org>
* punt unused clean/distclean targetsMike Frysinger2011-10-15-6/+0
| | | | | | | | | | 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.

* arm: tegra2: fix out-of-tree buildChe-liang Chiou2011-09-07-0/+4
| | | | | | | | | | | | | | | 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.
