2012-10-15tegra: clean up board include hellLucas Stach
The prototypes used in board files were all scattered out, which lead to code duplication between SPL and normal U-Boot and some prototypes not actually being used. Consolidate this in a common board header. Signed-off-by: Lucas Stach <dev@lynxeye.de> Acked-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
2012-07-09tegra: Allow boards to perform early GPIO setupThierry Reding
The new gpio_early_init() function, which does nothing by default, can be overridden by boards to configure GPIOs at an early stage. Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de> Acked-by: Stephen Warren <swarren@wwwdotorg.org> Signed-off-by: Tom Warren <twarren@nvidia.com>

2011-12-24tegra2: Move tegra2_mmc_init() prototype to public header.Thierry Reding
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.

2011-12-24tegra2: Plumb in SPI/UART switch codeSimon Glass
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.

2011-12-09tegra2: Add arch_cpu_init() to fire up Cortex-A9Simon Glass
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().

2011-12-09tegra2: Modify MMC driver to handle power and cd GPIOsStephen Warren
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.

2011-10-27tegra2: Enable MMC for SeaboardTom Warren
This adds the required GPIO and pinmux configuration to make eMMC / SD work on Seaboard. Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Tom Warren <twarren@nvidia.com>
2011-10-27tegra2: Clean up board code a littleSimon Glass
This removes clock_init() and pinmux_init() which are names better suited to those respective modules. By moving board_init_f() to the bottom of the file we can remove the need for so many functions in the board.h header file. The only clock/pinmux/gpio init we need to do prior to relocation is for the UART. Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Tom Warren <twarren@nvidia.com>
