* tegra: Add display support to funcmuxSimon Glass2012-11-19-0/+37
| | | | | | | Add support for a default pin mapping for display1. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
* tegra: Use const for pinmux_config_pingroup/table()Simon Glass2012-11-19-2/+2
| | | | | | | | | These two functions don't actually modify their arguments so add a const keyword. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
* tegra20: initialize variable to avoid compiler warningAllen Martin2012-10-29-1/+1
| | | | | | | | | | | Initialize this variable to avoid a compiler warning about possible use of uninitialized variable with gcc 4.4.6.

* tegra: add funcmux entry for NAND attached to KBCLucas Stach2012-10-15-1/+18
| | | | | | | | Secondary config for the Flash attachment. Signed-off-by: Lucas Stach <dev@lynxeye.de> Acked-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
* tegra20: add clock_set_pllout functionLucas Stach2012-10-15-1/+39
| | | | | | | | | | | Common practice on Tegra 2 boards is to use the pllp_out4 FO to generate the ULPI reference clock. For this to work we have to override the default hardware generated output divider. This function adds a clean way to do so.

* tegra20: complete periph_id enumLucas Stach2012-10-15-0/+1
| | | | | | | | | | | | Most Tegra boards output the ULPI reference clock on pad DEV2. Complete the periph_id enum so that we are able to enable this clock output circuit.

* Tegra20: Move some include files to arch-tegra for sharing with Tegra30Tom Warren2012-10-15-27/+27
| | | | | | | | | | | The move is pretty straight-forward. ap20.h and tegra20.h were renamed to ap.h and tegra.h. Some files remain in arch-tegra20 but 'include' a file in 'arch-tegra' with #defines & structs that will be common between T20 and T30 HW. HW-specific #defines, etc. stay in the 'arch-tegra20' 'root' file. All boards build OK w/MAKEALL -s tegra20. Checkpatch.pl runs clean. Seaboard works OK.

* Tegra20: Move some code files to common directories for upcoming Tegra30 ↵Tom Warren2012-10-15-467/+1
| | | | | | | | | | | | | | | | patches. Move files that are going to be common between T20 and T30 into 'tegra-common' subdirs in AVP (arm720t), CPU (armv7), and shared (arch/arm/cpu/.) areas. Any files that are left behind in '/tegra20' will be copied to '/tegra30' subdirs and modified for that SoC. The 'common' files should need only minor changes. Include files (arch/arm/include/asm/arch-tegra/tegra20) will be done in a follow-on patch. Builds fine w/MAKEALL -s tegra20. Checkpatch.pl is clean. Signed-off-by: Tom Warren <twarren@nvidia.com>
* Tegra: Change Tegra20 to Tegra in common code, prep for T30Tom Warren2012-09-10-19/+19
| | | | | | | | | | Convert TEGRA20_ defines to either TEGRA_ or NV_PA_ where appropriate. Convert tegra20_ source file and function names to tegra_, also. Upcoming Tegra30 port will use common code/defines/names where possible. Signed-off-by: Tom Warren <twarren@nvidia.com> Acked-by: Stephen Warren <swarren@nvidia.com>
* tegra: Add NAND support to funcmuxSimon Glass2012-09-07-0/+7

* tegra20: Remove armv4t build flagsAllen Martin2012-09-01-2/+0
| | | | | | | | | | | These flags were necessary when building tegra20 as a single binary that supported ARM7TDMI and Cortex A9. Now that the ARM7TDMI support is split into a separate SPL, this is no longer necessary.

* tegra20: enable SPL for tegra20 boardsAllen Martin2012-09-01-277/+4
| | | | | | | | | | | Add SPL options to tegra20 config files and enable SPL build for tegra20 boards. Also remove redundant code from u-boot that is not contained in SPL.

* tegra20: move SDRAM param save to later in bootAllen Martin2012-09-01-5/+0
| | | | | | | | | | | | Move warmboot_save_sdram_params() to later in the boot sequence. This code relies on devicetree to get the address of the memory controller and with upcoming changes for SPL boot it gets called early in the boot process when devicetree is not initialized yet.

* tegra20: move tegra20 SoC code to arch/arm/cpu/tegra20-commonAllen Martin2012-09-01-0/+4047
In preparation for splitting out the armv4t code from tegra20, move the tegra20 SoC code to arch/arm/cpu/tegra20-common. This code will be compiled armv4t for the arm7tdmi and armv7 for the cortex A9.
