2016-06-03arm: lib: import muldi3.S from LinuxMarek Vasut
Import muldi3.S from Linux 4.4.6 , commit 0d1912303e54ed1b2a371be0bba51c384dd57326 on arm32. This file implements __aeabi_lmul and it's alias __muldi3, which is needed when doing Thumb1 builds. This patch also defines CONFIG_THUMB2_KERNEL and CONFIG_ARM_ASM_UNIFIED which is necessary for correct build of these files both in ARM and Thumb mode, just like Linux does.

Import __do_div64 from Linux 4.4.6 , commit 0d1912303e54ed1b2a371be0bba51c384dd57326 on arm32. This function is for some toolchains, which generate _udivmoddi4() for 64 bit division. Since we do not support stack unwinding, instead of importing the whole asm/unwind.h and all the baggage, this patch defines empty UNWIND() macro.

2016-06-03arm: lib: Sync libgcc 32b division/modulo operationsMarek Vasut
Sync the libgcc 32bit division and modulo operations with Linux 4.4.6 , commit 0d1912303e54ed1b2a371be0bba51c384dd57326 . The functions in these four files are present in lib1funcs.S in Linux, so replace these files with lib1funcs.S from Linux. Since we do not support stack unwinding, instead of importing the whole asm/unwind.h and all the baggage, this patch defines empty UNWIND() macro in lib1funcs.S . Moreover, to make all of the functions available, define CONFIG_AEABI , which is safe, because U-Boot is always compiled with ARM EABI.

2016-06-03arm: include: Import unified.h from Linux kernelMarek Vasut
Import unified.h from Linux kernel 4.4.6 , commit 0d1912303e54ed1b2a371be0bba51c384dd57326 . This header file contains macros used in libgcc functions in Linux kernel on ARM and will be needed for the libgcc sync. Since unified.h defines the W(instr) macro, we must drop this from the macro from memcpy.S , otherwise this triggers a warning about symbol redefinition. In order to keep the changes to unified.h to the minimum, tweak arch/arm/lib/Makefile such that it defines the CONFIG_ARM_ASM_UNIFIED macro, which places .syntax unified into all of the assembler files. This is mandatory. Moreover, for Thumb2 build, define CONFIG_THUMB2_KERNEL macro if and only if Thumb2 build is enabled. This macro is checked by unified.h and toggles between ARM and Thumb2 variant of the instructions in the assembler source files. Finally, this patch defines __LINUX_ARM_ARCH__=N macro based on the new CONFIG_SYS_ARM_ARCH Kconfig option. This macro selects between more optimal and more dense codepaths which work on armv5 and newer and less optimal codepaths which work on armv4 and possible armv3m. Tegra2 needs the same special handling as it does in arch/arm/Makefile to cater for the arm720t boot core.

2016-06-01arm: socfpga: improve raw MMC SPL bootSylvain Lesne
Before this patch, when booting from MMC (no filesystem), the SPL loaded U-Boot from a fixed offset. It will now load U-Boot from an offset of 256kB (which is 4 times the padded SPL image) in the third partition. This behaviour is similar to what the vendor SPL (based on U-Boot 2013.01) does, and allows to directly 'dd' the u-boot-with-spl.sfp file to the A2 partition.

Remove the check for GD_FLG_SPL_INIT in spl_relocate_stack_gd(). The check will always fail. This is because spl_relocate_stack_gd() is called from ARM's crt0.S and it is called before board_init_r(). The board_init_r() calls spl_init(), which sets the GD_FLG_SPL_INIT flag. Note that reserving the malloc area in RAM is not a problem even if the GD_FLG_SPL_INIT flag is not set.

2016-05-31ARM: tegra: add p2771-0000 board supportStephen Warren
P2771-0000 is a P3310 CPU board married to a P2597 I/O board. The combination contains SoC, DRAM, eMMC, SD card slot, HDMI, USB micro-B port, Ethernet, USB3 host port, SATA, PCIe, and two GPIO expansion headers. Currently, due to U-Boot's level of support for Tegra186, the only features supported by U-Boot are the console UART and the on-board eMMC. Additional features will be added over time. U-Boot has so far been tested by replacing the kernel image on the device with a U-Boot binary. It is anticipated that U-Boot will eventually replace the CCPLEX bootloader binary, as on previous chips. This hasn't yet been tested.

2016-05-31ARM: tegra: add core Tegra186 supportStephen Warren
This adds the bare minimum code to support Tegra186, with UART and eMMC working. The empty gpio.h is required because <asm/gpio.h> includes it. A future cleanup round may be able to solve this for all Tegra generations at once. mach-tegra/Makefile is adjusted not to compile anything for Tegra186, but instead to defer everything to mach-tegra/tegra186/Makefile. This allows the SoC code to pick-and-choose which of the C files in the "common" mach-tegra/ directory to compile in based on the SoC's needs. Most of the code is not valid for Tegra186, and this approach removes the need for mach-tegra/Makefile to contain many SoC-specific ifdefs. This approach may be applied to all other Tegra SoCs in a future cleanup round. board186.c is introduced to replace board.c and board2.c. These files currently contain a slew of SoC- and board-specific code that is not valid for Tegra186. This approach avoids adding yet more ifdefs to those files. A future cleanup round may refactor most of board*.c into board-/ SoC-specific functions files thus allowing the top-level functions like board_init_early_f to be shared again.

2016-05-31mmc: tegra: add basic Tegra186 supportStephen Warren
Tegra186's MMC controller needs to be explicitly identified. Add another compatible value for it. Tegra186 will use an entirely different clock/reset control mechanism to existing chips, and will use standard clock/reset APIs rather than the existing Tegra-specific custom APIs. The driver support for that isn't ready yet, so simply disable all clock/reset usage if compiling for Tegra186. This must happen at compile time rather than run-time since the custom APIs won't even be compiled in on Tegra186. In the long term, the plan would be to convert the existing custom APIs to standard APIs and get rid of the ifdefs completely. The system's main eMMC will work without any clock/reset support, since the firmware will have already initialized the controller in order to load U-Boot. Hence the driver is useful even in this apparently crippled state. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>

2016-05-31Revert "image.h: Tighten up content using handy CONFIG_IS_ENABLED() macro."Masahiro Yamada
This reverts commit 56adbb38727320375b2f695bd04600d766d8a1b3. Since commit 56adbb387273 ("image.h: Tighten up content using handy CONFIG_IS_ENABLED() macro."), I found my boards fail to boot Linux because the commit changed the logic of macros it touched. Now, IMAGE_ENABLE_RAMDISK_HIGH and IMAGE_BOOT_GET_CMDLINE are 0 for all the boards. As you can see in include/linux/kconfig.h, CONFIG_IS_ENABLE() (and IS_ENABLED() as well) can only take a macro that is either defined as 1 or undefined. This is met for boolean options defined in Kconfig. On the other hand, CONFIG_SYS_BOOT_RAMDISK_HIGH and CONFIG_SYS_BOOT_GET_CMDLINE are defined without any value in arch/*/include/asm/config.h . This kind of clean-up is welcome, but the options should be moved to Kconfig beforehand. Moreover, CONFIG_IS_ENABLED(SPL_CRC32_SUPPORT) looks weird. It should be either CONFIG_IS_ENABLED(CRC32_SUPPORT) or IS_ENABLED(CONFIG_SPL_CRC32_SUPPORT). But, I see no define for CONFIG_SPL_CRC32_SUPPORT anywhere. Likewise for the other three. The logic of IMAGE_OF_BOARD_SETUP and IMAGE_OF_SYSTEM_SETUP were also changed for SPL. This can be a problem for boards defining CONFIG_SPL_OF_LIBFDT. I guess it should have been changed to IS_ENABLED(CONFIG_OF_BOARD_SETUP). In the first place, if we replace the references in C code, the macros IMAGE_* will go away. if (IS_ENABLED(CONFIG_OF_BOARD_SETUP) { ... } Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
