* ARM: move -march=* and -mtune= options to arch/arm/MakefileMasahiro Yamada2015-03-27-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | My main motivations for this commit are: [1] Follow the arch/arm/Makefile style of Linux Kernel [2] Maintain compiler options systematically Currently, we give -march=* and -mtune=* options inconsistently: Only some of the CPUs pass -march=* and -mtune=* options. By collecting such options into the single place arch/arm/Makefile we can tell which options are missing at a glance. [3] Prepare for deprecating arch/*/cpu/*/config.mk Note: This commit just moves the compiler options so as not to change the behavior at all. It does not care about the correctness of the given options. Fox example, "-march=armv5te" might be better than "-march=armv4" for ARM946EJS, but it is beyond the scope this commit. Also, filling the missing -march=* and -tune=* is left to follow-up patches.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | arch/arm/include/asm/spl.h requires all SoCs to have arch/arm/include/asm/arch-*/spl.h.

So they should not be archtecture specific, but be described as a simpile enumeration. This commit merges most of arch/arm/include/asm/arch-*/spl.h into arch/arm/include/asm/spl.h.

| * ARM: tegra: use a CPU freq that all SKUs can supportStephen Warren2014-05-13-7/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | U-Boot on Tegra30 currently selects a main CPU frequency that cannot be supported at all on some SKUs, and needs higher VDD_CPU/VDD_CORE values on some others. This can result in unreliable operation of the main CPUs. Resolve this by switching to a CPU frequency that can be supported by any SKU. According to the following link, the maximum supported CPU frequency of the slowest Tegra30 SKU is 600MHz: repo http://nv-tegra.nvidia.com/gitweb/?p=linux-2.6.git;a=summary branch l4t/l4t-r16-r2 path arch/arm/mach-tegra/tegra3_dvfs.c table cpu_dvfs_table[] According to that same table, the minimum VDD_CPU required to operate at that frequency across all SKUs is 1.007V. Given the adjustment resolution of the TPS65911 PMIC that's used on all Tegra30-based boards we support, we'll end up using 1.0125V instead. At that VDD_CPU, tegra3_get_core_floor_mv() in that same file dictates that VDD_CORE must be at least 1.2V on all SKUs. According to tegra_core_speedo_mv() (in tegra3_speedo.c in the same source tree), that voltage is safe for all SKUs. An alternative would be to port much of the code from tegra3_dvfs.c and tegra3_speedo.c in the kernel tree mentioned above. That's more work than I want to take on right now. While all the currently supported boards use the same regulator chip for VDD_CPU, different types of regulators are used for VDD_CORE. Hence, we add some small conditional code to select how VDD_CORE is programmed. If this becomes more complex in the future as new boards are added, or we end up adding code to detect the SoC SKU and dynamically determine the allowed frequency and required voltages, we should probably make this a runtime call into a function provided by the board file and/or relevant PMIC driver.

These lists are also auto- generated using scripts that were also used to generate the kernel pinctrl drivers. This ensures that the lists are consistent between the two. The entries in tegra124_pingroups[] are all updated to remove the columns which are no longer used. All affected code is updated to match. There are differences in the set of drive groups. I have validated this against the TRM. There are differences order of pin definitions in pinmux.c; these previously had significant mismatches with the correct order:-( I adjusted a few entries in pinmux-config-venice2.h since the set of legal functions for some pins was updated to match the TRM.

* ARM: tegra: use apb_misc.h in more placesStephen Warren2014-04-17-2/+4
| | | | | | | | | | | | | | | | | Tegra's "APB misc" register region contains various miscellaneous registers and the Tegra pinmux registers. Some code that touches the misc registers currently uses struct pmux_tri_ctlr, which is intended to be a definition of pinmux registers, rather than struct apb_misc_pp_ctrl, which is intended to be a definition of the miscellaneous registers. Convert all such code to use struct apb_misc_pp_ctrl, since struct pmux_tri_ctlr goes away in the next patch. This requires adding a missing field definition to struct apb_misc_pp_ctrl, and moving the header into a more common location.

| * ARM: tegra: simplify halt_avp()Stephen Warren2014-03-05-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to completely halt the AVP processor, we should simply write FLOW_MODE_STOP without any extra options that allow wakeup. Amend the code to do this. I believe that enabling FIQ_1 and IRQ_1 allow the CPU to be awoken by interrupts. We don't want this; if later SW wishes to use the AVP, it should be reset and booted from scratch. Related, the bits that were previously IRQ_1 and FIQ_1 have a slightly different definition starting with Tegra114, so the values we're writing don't entirely make sense there anyway.

* | kbuild: add CONFIG_ prefix to USE_PRIVATE_LIBGCCMasahiro Yamada2014-03-07-55/+0
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, USE_PRIVATE_LIBGCC was defined in arch-specific config.mk and referenced in arch/$(ARCH)/lib/Makefile. We are not happy about parsing config.mk again and again. We have to keep the same behavior with a different way. By adding "CONFIG_" prefix, this macro appears in include/autoconf.mk, include/spl-autoconf.mk. (And treating USE_PRIVATE_LIBGCC as CONFIG macro is reasonable enough.) Tegra SoC family defined USE_PRIVATE_LIBGCC as "yes" in arch/arm/cpu/arm720t/tegra*/config.mk, whereas did not define it in arch/arm/cpu/armv7/tegra*/config.mk. It means Tegra enables PRIVATE_LIBGCC only for SPL. We can describe the same behavior by adding #ifdef CONFIG_SPL_BUILD # define CONFIG_USE_PRIVATE_LIBGCC #endif to include/configs/tegra-common.h.

* ARM: tegra: don't exceed AVP limits when configuring PLLPJimmy Zhang2014-02-03-51/+3
| | | | | | | | | | | | | | | | | | | | | | | | Based on the Tegra TRM, the system clock (which is the AVP clock) can run up to 275MHz. On power on, the default sytem clock source is set to PLLP_OUT0. In function clock_early_init(), PLLP_OUT0 will be set to 408MHz which is beyond system clock's upper limit. The fix is to set the system clock to CLK_M before initializing PLLP, and then switch back to PLLP_OUT4, which has an appropriate divider configured, after PLLP has been configured Implement this logic in new function tegra30_set_up_pllp(), which sets up PLLP and all PLLP_OUT* dividers, and handles the AVP clock switching. Remove the duplicate PLLP setup from pllx_set_rate() and adjust_pllp_out_freqs().

Adjust pmc.h to reflect this, and update any code affected by the change. The cpu.c change in this patch was extracted from a much larger patch by Jimmy Zhang. The pmc.h change was written from scratch, but inspired by related changes made by Tom Warren. There could well be other differences in the PMC register set for chips after Tegra20/30. However, they don't affect the code in U-Boot at present, so I haven't attempted an exhaustive update of pmc.h.

| | | | | | | | | | | | Use __image_copy_end instead of __bss_start for the end of the image to relocate. This is the same as commit 033ca72, but applied to all ARM start.S. This is a more appropriate symbol naming for an image copy & relocate feature, and this also saves a useless copy of data put between __image_copy_end and __bss_start in linker scripts (e.g. relocation information, or MMU initialization tables used only before jumping to the relocated image).

| * ARM: tegra: implement WAR for Tegra114 CPU reset vectorStephen Warren2013-03-14-4/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | A Tegra114 HW bug prevents the main CPU vector from being modified under certain circumstances. Tegra114 A01P and later with a patched boot ROM set the CPU reset vector to 0x4003fffc (end of IRAM). This allows placing an arbitrary jump instruction at that location, in order to redirect to the desired reset vector location. Modify Tegra114's start_cpu() to make use of this feature. This allows CPUs with the patched boot ROM to boot. Based-on-work-by: Jimmy Zhang <jimmzhang@nvidia.com>.

This is needed so that the SDIO slot power can be brought up for the MMC driver, so it has to precede those commits.

* | Replace __bss_end__ with __bss_endSimon Glass2013-03-15-1/+1
|/ | | | | | | | | | | | | Note this is a tree-wide change affecting multiple architectures. At present we use __bss_start, but mostly __bss_end__. This seems inconsistent and in a number of places __bss_end is used instead. Change to use __bss_end for the BSS end symbol throughout U-Boot. This makes it possible to use the asm-generic/sections.h file on all archs. Signed-off-by: Simon Glass <sjg@chromium.org>
