* tegra: Whistler board supportStephen Warren2012-07-07-0/+231
| | | | | | | | | | | | | | | | | | | Whistler is a highly configurable Tegra evaluation and development board. This change adds support for the following specific configuration: E1120 motherboard E1108 CPU board E1116 PMU board The motherboard configuration switches are set as follows: SW1=0 SW2=0 SW3=5 S1/S2/S3/S4 all on, except S3 7/8 are off. Other combinations of daugher boards may work to varying degrees, but will likely require some SW adjustment.

* spi: Tegra2: Seaboard: fix UART corruption during SPI transactionsTom Warren2012-07-07-20/+7
| | | | | | | | | | | Simon Glass's proposal to fix this on Seaboard was NAK'd, so I removed his NS16550 references and added a small delay before SPI/UART muxing. Tested on my Seaboard with large SPI reads/writes and saw no corruption (crc's matched) and no spurious comm chars.

* tegra: Turn off power detect in board initWei Ni2012-05-15-0/+18
| | | | | | | | | | | Tegra core power rail has leakage voltage around 0.2V while system in suspend mode. The source of the leakage should be coming from PMC power detect logic for IO rails power detection. That can be disabled by writing a '0' to PWR_DET_LATCH followed by writing '0' to PWR_DET (APBDEV_PMC_PWR_DET_0).

* tegra2: Plumb in SPI/UART switch codeSimon Glass2011-12-24-0/+12
| | | | | | | | | | | | | | | 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/+185
| | | | | | | | | | | | | | | | 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: Add arch_cpu_init() to fire up Cortex-A9Simon Glass2011-12-09-4/+0
| | | | | | | | | | | | | 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().

| | | | | | | | | | | | | | | ... 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.

| | | | | | | | | | | | | | | | | | | | | | | 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 Warren2011-12-09-52/+109
| | | | | | | | | | | | | | | | | | | | 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().
