* TI ARMv7: Don't use GD before crt0.S has set itTom Rini2015-01-16-8/+1
| | | | | | | | | | | | | | | | | Prior to this change we set the gd pointer early so that we can store data in it. This becomes problematic for DM changes as well as being odd in general. Re-work the code paths so that we don't need to set the gd pointer so early and instead can rely upon the normal setting of it. In order to do this we do need to move certain calls from s_init into spl_board_init(), mainly preloader_console_init and save_omap_boot_params. Tested on: Beaglebone Black, AM43xx GP EVM, Beagleboard, Beagleboard xM, OMAP5 uEVM, DRA7xx EVM Signed-off-by: Tom Rini <trini@ti.com> Tested-by: Simon Glass <sjg@chromium.org> Reviewed-by: Simon Glass <sjg@chromium.org>

* kconfig: arm: introduce symbol for ARM CPUsGeorges Savoundararadj2014-10-29-3/+0
| | | | | | | | | | | | | | | | | This commit introduces a Kconfig symbol for each ARM CPU: CPU_ARM720T, CPU_ARM920T, CPU_ARM926EJS, CPU_ARM946ES, CPU_ARM1136, CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100. Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected for CPU_ARM1176 and CPU_V7. For each target, the corresponding CPU is selected and the definition of SYS_CPU in the corresponding Kconfig file is removed. Also, it removes redundant "string" type in some Kconfig files.

* 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>

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

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

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