* ARM: tegra: Tegra20 pinmux cleanupStephen Warren2014-04-17-11/+11
| | | | | | | | | | | | | | This renames all the Tegra20 pinmux pins and functions so they have a prefix which matches the type name. The entries in tegra20_pingroups[] are all updated to remove the columns which are no longer used. All affected code is updated to match.

* dts: move device tree sources to arch/$(ARCH)/dts/Masahiro Yamada2014-02-19-91/+0
| | | | | | | | | | | | | | | | | Unlike Linux Kernel, U-Boot historically had *.dts files under board/$(VENDOR)/dts/ and *.dtsi files under arch/$(ARCH)/dts/. I think arch/$(ARCH)/dts dicretory is a better location to store both *.dts and *.dtsi files. For example, before this commit, board/xilinx/dts directory had both Microblaze dts (microblaze-generic.dts) and ARM dts (zynq-*.dts), which are totally unrelated. This commit moves *.dts to arch/$(ARCH)/dts/ directories, allowing us to describe nicely mutiple DTBs generation in the next commit. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* kbuild: change out-of-tree buildMasahiro Yamada2014-02-19-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit changes the working directory where the build process occurs. Before this commit, build process occurred under the source tree for both in-tree and out-of-tree build. That's why we needed to add $(obj) prefix to all generated files in makefiles like follows: $(obj)u-boot.bin: $(obj)u-boot Here, $(obj) is empty for in-tree build, whereas it points to the output directory for out-of-tree build. And our old build system changes the current working directory with "make -C <sub-dir>" syntax when descending into the sub-directories. On the other hand, Kbuild uses a different idea to handle out-of-tree build and directory descending. The build process of Kbuild always occurs under the output tree. When "O=dir/to/store/output/files" is given, the build system changes the current working directory to that directory and restarts the make. Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>" syntax for descending into sub-directories. (We can write it like "make $(obj)=<sub-dir>" with a shorthand.) This means the current working directory is always the top of the output directory. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Tested-by: Gerhard Sittig <gsi@denx.de>

* Makefile: convert makefiles to Kbuild style and delete grep switchMasahiro Yamada2013-11-01-21/+1
| | | | | | | | | | | | | We have converted all makefiles needed to build $(LIBS). Until this commit we used to grep switch so that U-Boot style and Kbuild style makefiles coexist. But we do not need any more. Goint forward, use always Kbuild style Makefile when adding a new Makefile Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* Tegra: MMC: Add DT support to MMC driver for all T20 boardsTom Warren2013-03-14-25/+1
| | | | | | | | | | | | tegra_mmc_init() now parses the DT info for bus width, WP/CD GPIOs, etc. Tested on Seaboard, fully functional. Tamonten boards (medcom-wide, plutux, and tec) use a different/new dtsi file w/common settings.

* ARM: tegra: enable 8-bit SD slots in board filesStephen Warren2012-11-19-3/+2
| | | | | | | | | | | | | | | | | | | | Harmony contains an SD slot with all 8 bits routed. This allows plugging in an eMMC-chip-in-SD-form-factor. Seaboard/Springbank/Ventana/AC100 all have an eMMC chip with all 8 bits hooked up. Now that the U-Boot eMMC code fully supports 8-bit operation, initialize those ports as 8-bit instead of 4-bit to improve performance. Whistler was already registering its ports as 8-bit. TrimSlice doesn't have any 8-bit ports. I don't have any Avionic Design boards nor the Colibri board to test with.

* tegra: move common features to a common makefileMarc Dietrich2012-10-29-2/+4
| | | | | | | | | | | | | | | | | | | For Non-Nvidia boards to include newly added features (like emc clock scaling) it would be necessary to add each feature to their own board Makefile. This is because currently the top Makefile automaticly includes these features only for Nvidia boards. This patch adds a simple Makefile include so all new features become available for non-Nvidia board vendors.

* tegra20: rework UART GPIO handlingLucas Stach2012-10-15-7/+0
| | | | | | | | | | | | | | | | | | | | Rename board provided gpio_config_uart() to gpio_early_init_uart() as it does the same thing as the equally called function provided by the uart-switch code. This allows to simply call this function in early board init whether or not we are building with CONFIG_UART_SWITCH defined. Also provide a weak symbol for this function, to avoid the need to provide this function for boards that don't need any fixup. This patch supersedes the earlier posted "tegra: convert gpio_config_uart to weak symbol".

* Tegra20: Move some include files to arch-tegra for sharing with Tegra30Tom Warren2012-10-15-2/+2
| | | | | | | | | | | 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.

* tegra2: Add support for Compal Paz00 (Toshiba AC100)Stephen Warren2012-02-12-0/+122
The Toshiba AC100 (Compal code-name Paz00, aka Dynabook AZ) is a netbook derived from the NVIDIA Tegra Harmony reference board. It ships with Android, but is often repurposed to run Linux. This patch adds just enough support to get a U-Boot serial console, and the ability access built-in eMMC and the external SD slot. v2: * Rebased on latest HEAD, incorporated changes made to other board files. * Moved board files from board/nvidia to board/compal. * Switched to correct odmdata value. This required add the previous patch to fix U-Boot's interpretation of the odmdata RAM size field. * Removed nvmem= from default Linux kernel command-line; no drivers use the reserved memory yet, so there's no point reserving it.
