* mx5 clocks: CleanupBenoît Thébaudeau2012-10-15-146/+91
| | | | | | | | | | Clean up the i.MX5 clock driver: - Use readl() and writel() instead of their __raw_ counterparts. - Use the clr/setbits_le32() family of macros rather than expanding code. - Use accessor macros for bit-fields instead of _MASK and _OFFSET.

| | | | | | | | | | | | | Add meaningful constants for each clock channels and use them for enabling and disabling i.MX6 clocks. Includes an update to enable/disable the IPU1 clock in drivers/video/ipu_common to remove IMX5x register access when used on i.MX6 as discussed in V1: http://patchwork.ozlabs.org/patch/185129/ Signed-off-by: Eric Nelson <eric.nelson@boundarydevices.com>
* Tegra20: Move some include files to arch-tegra for sharing with Tegra30Tom Warren2012-10-15-6/+6
| | | | | | | | | | | 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 Warren2012-10-15-1/+48
| | | | | | | | | | | | | | | | 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>
* tegra20: add USB ULPI init codeLucas Stach2012-10-15-22/+131
| | | | | | | | | | | | | 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.

* ARM: prevent misaligned array initsAlbert ARIBAUD2012-10-15-2/+5
| | | | | | | | | | | | | | 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.

* arm: armv7: omap3: Fix restore sequence in lowlevel_initAlbert ARIBAUD2012-10-08-5/+4
| | | | | | | | | | | 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.

* arm: rmobile: bugfix: wrong register saving in lowlevel_initTetsuyuki Kobayashi2012-10-08-11/+1
| | | | | | | | lowlevel_init() of rmobile badly assumed that ip register holds return address. The commit "63ee53a7 armv7 cpu_init_crit: Simplify code" breaks this assumption. This patch removes this bad assumption and simplify code. Signed-off-by: Tetsuyuki Kobayashi <koba@kmckk.co.jp>
* arm: armv7: temporarily set -mno-unaligned-accessAlbert ARIBAUD2012-10-05-0/+2
| | | | | | | | | This patch aims at ensuring that the 2012.10 release works out-of-the-box on as many targets as possible, by reinstating commit 5347560f5427bcdd48a563b62180481606ac8044, which adds option -mno-unaligned-access to armv7 builds. This patch will be overriden immediately after release of 2012.10.

| | | | | | | | | | | Latest rmobile code was tested by using old gcc (gcc-4.4). When we use gcc-4.6 (or later), the build is made, but does not work. This solves a problem not to work by add -march=armv5 to compiple option when we built in gcc-4.6 (or later). I tested by linaro's compiler version 2012.04-20120426.

* SPL: Create arch/arm/lib/spl.c for board_init_f and jump_to_image_linuxTom Rini2012-09-27-11/+11
| | | | | | | | | | | | | | In SPL (CONFIG_SPL_FRAMEWORK) board_init_f must setup the stack pointer, clear the BSS and call board_init_r. We mark this as weak as some platforms may need to perform additional initalization at this point. We provide a gd that we know will be in a usable location, once the BSS has been cleared to help with this as well. Finally, we no longer call relocate_code so remove that from the armv7 version. Next, both board_init_f and jump_to_image_linux are going to be inherently arch-specific, so move these versions to arch/arm/lib/spl.c Signed-off-by: Tom Rini <trini@ti.com>
* SPL: Move the omap SPL framework to common/splTom Rini2012-09-27-449/+5
| | | | | | | | | | | | | Add a new flag, CONFIG_SPL_FRAMEWORK to opt into the common/spl SPL framework, enable on all of the previously using boards. We move the spl_ymodem.c portion to common/ and spl_mmc.c to drivers/mmc/. We leave the NAND one in-place as we plan to replace it later in this series. We use common/spl to avoid linker problems with respect to merging constant strings in objects. Otherwise all strings in common/ will be linked in and kept which grows SPL in size too much.

| | | | | | | | | | | | | - Remove includes we don't need - Switch some printf statements to puts - Convert some printf statements to debug, introduce new puts statements - In most cases saying just "No mkimage signature, assuming u-boot.bin" or similar is sufficient. This also means the non-DEBUG case doesn't need printf, in the core of SPL. - The other case here is that PLAIN_VERSION provided what we wanted already, so just use it.
