* ARM: omap: merge GPMC initialization code for all platformpekon gupta2014-05-23-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GPMC controller on TI's OMAP SoC is general purpose controller to interface with different types of external devices like; - parallel NOR flash - parallel NAND flash - OneNand flash - SDR RAM - Ethernet Devices like LAN9220 Though GPMC configurations may be different for each platform depending on clock-frequency and external device interfacing with controller. But initialization sequence remains common across all platfoms. Thus this patch merges gpmc_init() scattered in different arch-xx/mem.c files into single omap-common/mem-common.c However, actual platforms specific register config values are still sourced from corresponding platform specific headers like; AM33xx: arch/arm/include/asm/arch-am33xx/mem.h OMAP3: arch/arm/include/asm/arch-omap3/mem.h OMAP4: arch/arm/include/asm/arch-omap4/mem.h OMAP4: arch/arm/include/asm/arch-omap5/mem.h Also, CONFIG_xx passed by board-profile decide config for which set of macros need to be used for initialization CONFIG_NAND: initialize GPMC for NAND device CONFIG_NOR: initialize GPMC for NOR device CONFIG_ONENAND: initialize GPMC for ONENAND device Signed-off-by: Pekon Gupta <pekon@ti.com> [trini: define GPMC_SIZE_256M for omap3] Signed-off-by: Tom Rini <trini@ti.com>

* ARM: OMAP: replace custom sr32() by standard I/O accessorsWolfgang Denk2014-04-17-163/+205
| | | | | | | | | | | | | | | | | | Replace the custom bit manipulation function sr32() by standard I/O accessors. A major motivation for this cleanup was the fact, that a number of calls of that function resulted in 32 bit wide shift operations on u32 data, which according to the C-ISO/IEC-9899-Standard provokes undefined behaviour: 6.5.7 Bitwise shift operators ... If the value of the right operand is negative or is greater than or equal to the width of the promoted left operand, the behavior is undefined.

* 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>

* | arm: omap3: Enable clocks for peripherals only if they are usedMichael Trimarchi2013-12-06-2/+0
|/ | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | 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.

* arm, omap3: fix warm reset serial output on OMAP36xx/AM/DM37xxMatt Porter2012-05-15-0/+16
| | | | | | | | | | | | | | | | 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>

* armv7: omap3: leave outer cache enabledAneesh V2012-02-27-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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.
