2014-02-19kbuild: change out-of-tree buildMasahiro Yamada
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>

2013-12-06arm: omap3: Enable clocks for peripherals only if they are usedMichael Trimarchi
This patch change the per_clocks_enable() function used in OMAP3 code to enable peripherals clocks. Only required clock should be activated. So if the board use the uart(x) as a console we need to activate it. The Board's config should include define to enable every subsystem that the board use. For a complete list of affected peripherals, registers CM_FCLKEN_PER and CM_ICLKEN_PER should be checked. Right now the bootloader can enable and disable clocks for: uart(x) using CONFIG_SYS_NS16550 gpio bank (x) using CONFIG_OMAP3_GPIO_X with X = { 2, 3, 4, 5, 6 } i2c bus using CONFIG_DRIVER_OMAP34XX_I2C. Not required gptimer(x) and mcbsp(x) for booting are disabled by default and are not supported by any define. Their activation need to included in the per_clocks_enable if the peripheral is included. Not booting board should enable the peripheral clock connected to their driver Signed-off-by: Michael Trimarchi <michael@amarulasolutions.com> Cc: Igor Grinberg <grinberg@compulab.co.il> Cc: Tom Rini <trini@ti.com> Acked-by: Igor Grinberg <grinberg@compulab.co.il>

2013-08-15ARM: omap3: Implement dpll5 (HSUSB clk) workaround for OMAP36xx/AM/DM37xx ↵Naumann Andreas
according to errata sprz318e. In chapter 'Advisory 2.1 USB Host Clock Drift Causes USB Spec Non-compliance in Certain Configurations' of the TI Errata it is recommended to use certain div/mult values for the DPLL5 clock setup. So far u-boot used the old 34xx values, so I added the errata recommended values specificly for 36xx init only. Also, the FSEL registers exist no longer, so removed them from init. Tested this on a AM3703 board with 19.2MHz oscillator, which previously couldnt lock the dpll5 (kernel complained). As a consequence the EHCI USB port wasnt usable in U-Boot and kernel. With this patch, kernel panics disappear and USB working fine in u-boot and kernel.

2012-09-27SPL: Create arch/arm/lib/spl.c for board_init_f and jump_to_image_linuxTom Rini
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>
2012-09-27SPL: Move the omap SPL framework to common/splTom Rini

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. Signed-off-by: Tom Rini <trini@ti.com>

2012-05-15arm, omap3: fix warm reset serial output on OMAP36xx/AM/DM37xxMatt Porter
In warm reset conditions on OMAP36xx/AM/DM37xx the rom code incorrectly sets the DPLL4 clock input divider to /6.5 which is an invalid value unless the input clock is 13MHz. When a JTAG emulator is attached, a warm reset is necessary after the emulator gains control of the process. This results in a loss of serial output due to the invalid DPLL4 settings. This patch fixes the issue by resetting the DPLL4 clock input divider to /1 when the input clock is not 13MHz. AM/DM37x TRM section 3.5.3.3.3.2.1 specifies that the /6.5 setting is only used when the input clock is 13MHz. Signed-off-by: Matt Porter <mporter@ti.com>

2012-02-27armv7: omap3: leave outer cache enabledAneesh V
Mainline kernel for OMAP3 doesn't enable L2 cache It expects L2$ to be enabled by ROM-code/bootloader. Leaving L2$ enabled can be troublesome in cases where the L2 cache is not under CP15 control, such as in Cortex-A9. This problem is explained in detail in the commit dc7100f4080952798413fb63bb4134b22c57623a However, this problem doesn't apply to Cortex-A8 because L2$ in Cortex-A8 is under CP15 control and hence the generic armv7 maintenance opertions work for it. As such we can make an exception for OMAP3 and leave the L2$ enabled when we jump to kernel. This is done by removing the strongly-linked implementation of v7_outer_cache_disable() and allowing it to fall back to the weakly linked implementation that doesn't do anything.
