b2f1858455 arm: lib: fix push/pop-section directives
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).

e2924e5904 ARM: k2g: Configure reset mux to device reset
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.

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

36080228ed ARM: DRA7: Update/Correct MPU and CORE OPP_NOM voltage values
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.

91b86e2156 lib: Enable private libgcc by default
This patch decouples U-Boot binary from the toolchain on systems where
private libgcc is available. Instead of pulling in functions provided
by the libgcc from the toolchain, U-Boot will use it's own set of libgcc
functions. These functions are usually imported from Linux kernel, which
also uses it's own libgcc functions instead of the ones provided by the
toolchain.

This patch solves a rather common problem. The toolchain can usually
generate code for many variants of target architecture and often even
different endianness. The libgcc on the other hand is usually compiled
for one particular configuration and the functions provided by it may
or may not be suited for use in U-Boot. This can manifest in two ways,
either the U-Boot fails to compile altogether and linker will complain
or, in the much worse case, the resulting U-Boot will build, but will
misbehave in very subtle and hard to debug ways.

c0db6f8d20 arm: include: Import unified.h from Linux kernel
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.

loaded U-Boot from a fixed offset.
It will now load U-Boot from an offset of 256kB (which is 4 times the

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.

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.

10a03382f0 ARM: tegra: add p2771-0000 board support
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.

c7ba99c8c1 ARM: tegra: add core Tegra186 support
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.

39f633320c mmc: tegra: add basic Tegra186 support
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.

074a1fdd27 gpio: add Tegra186 GPIO driver
Tegra186's GPIO controller register layout is significantly different from
previous chips, so add a new driver for it. In fact, there are two
different GPIO controllers in Tegra186 that share a similar register
layout, but very different port mapping. This driver covers both.

The DT binding is already present in the Linux kernel (in linux-next via
the Tegra tree so far).

601800be22 ARM: tegra: convert CONFIG_TEGRA_GPIO to Kconfig
Future chips will contain different GPIO HW. This change will enable
future SoC support to select the appropriate GPIO driver for their HW,
in a future-looking fashion, using Kconfig.

TEGRA_GPIO is not simply selected by TEGRA_COMMON (even though all
current Tegra chips used this GPIO HW) to simplify the later addition
of support for Tegra SoCs that use different GPIO HW.

e6bf0ca0e2 ARM: tegra: fix naming in GPIO DT binding header
According to the Tegra TRM, GPIOs are aggregated into /ports/ of 8 GPIOs,
not into /banks/. Fix <dt-bindings/gpio/tegra-gpio.h> to correctly reflect
this naming convention. While this seems like silly churn, it will become
slightly more important once we introduce the GPIO binding for upcoming
Tegra chips. This mirrors an identical commit in the Linux kernel.
