2012-10-15tegra: nand: add board pinmuxLucas Stach

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>

2012-10-15tegra20: rework UART GPIO handlingLucas Stach
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". Build tested with MAKEALL -s tegra20 Signed-off-by: Lucas Stach <dev@lynxeye.de> Acked-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
2012-10-15tegra20: add clock_set_pllout functionLucas Stach
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. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Tom Warren <twarren@nvidia.com>

2012-10-15Tegra20: Move some include files to arch-tegra for sharing with Tegra30Tom Warren
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. Signed-off-by: Tom Warren <twarren@nvidia.com>
2012-10-15Tegra20: Move some code files to common directories for upcoming Tegra30 ↵Tom Warren
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>
2012-10-15tegra20: add USB ULPI init codeLucas Stach
This adds the required code to set up a ULPI USB port. It is mostly a port of the Linux ULPI setup code with some tweaks added for more correctness, discovered along the way of debugging this. To use this both CONFIG_USB_ULPI and CONFIG_USB_ULPI_VIEWPORT have to be set in the board configuration file.

2012-10-15tegra20: port to new ehci interfaceLucas Stach

2012-10-15usb: ehci: rework to take advantage of new lowlevel interfaceLucas Stach
Kill off ehci-core.h It was used to specify some static controller data. To support more than one controller being active at any time we have to carry the controller data ourselfes. Change the ehci interface accordingly. NOTE: OMAP implemented the ehci stuff a bit backwards and should be fixed to do the same thing as other platforms. But the change for now is at least compile clean. Signed-off-by: Lucas Stach <dev@lynxeye.de> Reviewed-by: Marek Vasut <marex@denx.de>

2012-10-15ARM: prevent misaligned array initsAlbert ARIBAUD
Under option -munaligned-access, gcc can perform local char or 16-bit array initializations using misaligned native accesses which will throw a data abort exception. Fix files where these array initializations were unneeded, and for files known to contain such initializations, enforce gcc option -mno-unaligned-access.

2012-10-08arm: armv7: omap3: Fix restore sequence in lowlevel_initAlbert ARIBAUD
The restore sequence in lowlevel_init was in the wrong order, causing lr to lose its original value and be set equal to ip instead. Also, its use of the stack clashes with that of s_init, so move the s_init call after the restore and turn it into a tail-optimized branch.

2012-10-08arm: rmobile: bugfix: wrong register saving in lowlevel_initTetsuyuki Kobayashi
