2016-06-03arm: lib: fix push/pop-section directivesStephen Warren
With the existing code, function symbols are defined in .text, and the body is defined in .text.xxx. This causes (at least some version of) the linker not to emit the function body into the final binary, since it's part of a different section to the symbols being referenced. This of course causes a wide variety of failures. This change moves the push/pop-section directives before the function symbols, and after any relate ENDPROC macro invocations, so that symbols and bodies are all in the "pushed" sections, and thus the function bodies are emitted into the binary. This solves (at least) the boot problems currently seen on Tegra systems that use SPL (i.e. all ARMv7 Tegras).

2016-06-02ARM: k2g: Configure reset mux to device resetLokesh Vutla
BOOTCFG_RSTMUX8 register controls the reset mux associated with the ARM. Timer5(dedicated to ARM) when used as WatchDog timer, the events it generates are routed to the above mux. Following are the 3 events that can controlled bt the reset mux: - Device Reset - An interrupt to the ARM_GIC - An interrupt to the ARM_GIC followed by a device reset. Right now to give a default watchdog behaviour "Device reset" is being selected. Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Acked-by: Nishanth Menon <nm@ti.com>

2016-06-02ARM: DRA7: Add macros for voltage values for all OPPsAnna, Suman
Define specific macros for the voltage values for all voltage domains for all applicable OPPs - OPP_NOM, OPP_OD and OPP_HIGH. No separate macros are defined for VD_MPU and VD_CORE at OPP_OD and OPP_HIGH as these use the same values as OPP_NOM. The current macros will be used as common macros that can be redefined appropriately based on a selected OPP configuration at build time.

2016-06-02ARM: DRA7: Consolidate voltage macros across different SoCsAnna, Suman
The voltage values for each voltage domain at an OPP is identical across all the SoCs in the DRA7 family. The current code defines one set of macros for DRA75x/DRA74x SoCs and another set for DRA72x macros. Consolidate both these sets into a single set. This is done so as to minimize the number of macros used when voltage values will be added for other OPPs as well.

Define a set of common macros for the efuse register offsets (different for each OPP) that are used to get the AVS Class 0 voltage values and ABB configuration values. Assign these common macros to the register offsets for OPP_NOM by default for all voltage domains. These common macros can then be redefined properly to point to the OPP specific efuse register offset based on the desired OPP to program a specific voltage domain.

2016-06-02ARM: DRA7: Update/Correct MPU and CORE OPP_NOM voltage valuesAnna, Suman
The current OPP_NOM voltage values defined for the MPU and CORE voltage domains are based on the initial DRA75x_74x_SR1.1_DM data manual. As per this DM, the PMIC boot voltage can be set to either 1.10V or 1.15V for VD_MPU, and either 1.06V or 1.15V for VD_CORE. While the current values are correct, the latter set of values are the values that are common across all DRA75x, DRA72x SoCs and for all current Silicon revisions. So, update both the MPU and CORE OPP_NOM voltages to 1.15V. The macros are also slightly reorganized so that both the MPU and CORE voltage domain values are defined together.

2016-06-02arm: 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.
