d73718f323 armv8: Enable CPUECTLR.SMPEN for coherency
For A53, data coherency is enabled only when the CPUECTLR.SMPEN bit is
set. The SMPEN bit should be set before enabling the data cache.
If not enabled, the cache is not coherent with other cores and
data corruption could occur.

For A57/A72, SMPEN bit enables the processor to receive instruction
cache and TLB maintenance operations broadcast from other processors
in the cluster. This bit should be set before enabling the caches and
MMU, or performing any cache and TLB maintenance operations.

0de02de768 arm: Fix setjmp (again)
Commit e677724 (arm: Fix setjmp) added code to fix compilation of the setjmp
code path with thumv1. Unfortunately it missed a constraint that the adr
instruction can only refer to 4 byte aligned offsets.

So this patch adds the required alignment hooks to make compilation
work again even when setjmp doesn't happen to be 4 byte aligned.

ec5507707a video: tegra: Move to using simple-panel and pwm-backlight
We have standard drivers for panels and backlights which can do most of the

This patch includes device tree changes for the nvidia boards. I have only
been able to test seaboard. If this patch is applied, these boards will
also need to be synced with the kernel, and updated to use display-timings:

The later one is important, since in certain cases, it is desired that

9f823615af Kconfig: Add a new DISTRO_DEFAULTS Kconfig option
DISTRO_DEFAULTS is intended to mirror / replace
include/config_distro_defaults.h.

The intend is for boards which include this file to select this from
their Kconfig files and when moving setting to Kconfig which are #define-ed
in config_distro_defaults.h to select this from DISTRO_DEFAULTS so that
boards which have selected DISTRO_DEFAULTS will keep the same configuration
as before without needing any defconfig file changes.

The initial list of selected things matches all settings recently removed
from config_distro_defaults.h because they have been converted to Kconfig,
with the exception of CMD_ELF and CMD_NET, which have a default of y, if
the default of these ever changes they should be selected by DISTRO_DEFAULTS
too.

For testing and example purposes this commit also converts ARCH_SUNXI
to use DISTRO_DEFAULT instead of selecting everything it needs itself.

4257f5f8f6 sunxi: Add PSCI implementation in C
To make the PSCI backend more maintainable and easier to port to newer

Some inline assembly bits are required to access coprocessor registers.
PSCI stack setup is the only part left completely in assembly. In theory
this part could be split out of psci_arch_init into a separate common

b56e06d343 ARM: allocate extra space for PSCI stack in secure section during link phase
The PSCI implementation expects at most 2 pages worth of space reserved
at the end of the secure section for its stacks. If PSCI is relocated to
secure SRAM, then everything is fine. If no secure SRAM is available,
and PSCI remains in main memory, the reserved memory space doesn't cover
the space used by the stack.

If one accesses PSCI after Linux has fully booted, the memory that should
have been reserved for the PSCI stacks may have been used by the kernel
or userspace, and would be corrupted. Observed after effects include the
system hanging or telinit core dumping when trying to reboot. It seems
the init process gets hit the most on my test bed.

This fix allocates the space used by the PSCI stacks in the secure
section by skipping pages in the linker script, but only when there is
no secure SRAM, to avoid bloating the binary.

This fix is only a stop gap. It would be better to rework the stack
allocation mechanism, maybe with proper usage of CONFIG_ macros and an
explicit symbol.

135aa95002 clk: convert API to match reset/mailbox style
The following changes are made to the clock API:
* The concept of "clocks" and "peripheral clocks" are unified; each clock
  provider now implements a single set of clocks. This provides a simpler
  conceptual interface to clients, and better aligns with device tree
  clock bindings.
* Clocks are now identified with a single "struct clk", rather than
  requiring clients to store the clock provider device and clock identity
  values separately. For simple clock consumers, this isolates clients
  from internal details of the clock API.
* clk.h is split so it only contains the client/consumer API, whereas
  clk-uclass.h contains the provider API. This aligns with the recently
  added reset and mailbox APIs.
* clk_ops .of_xlate(), .request(), and .free() are added so providers
  can customize these operations if needed. This also aligns with the
  recently added reset and mailbox APIs.
* clk_disable() is added.
* All users of the current clock APIs are updated.
* Sandbox clock tests are updated to exercise clock lookup via DT, and
  clock enable/disable.
* rkclk_get_clk() is removed and replaced with standard APIs.

Buildman shows no clock-related errors for any board for which buildman
can download a toolchain.

test/py passes for sandbox (which invokes the dm clk test amongst
others).

51ea5a060d ARM: uniphier: reserve memory for DRAM PHY training on PH1-LD20
The DRAM PHY layer on PH1-LD20 is able to calibrate PHY parameters
periodically.  This compensates for the voltage and temperature
deviation and improves the PHY parameter adjustment.  Instead, it
requires 64 byte scratch memory in each DRAM channel for the dynamic
training.  The memory regions must be reserved in DT before jumping
to the kernel.

The scratch area can be anywhere in each DRAM channel, but the DRAM
init code in SPL currently assigns it at the end of each channel.
So, it makes sense to reserve the regions on run-time by U-Boot
instead of statically embedding it in the DT in Linux.  Anyway,
a boot-loader should know much more about memory initialization
than the kernel.

5bc88cc2be sunxi: Downclock AHB1 to 100MHz on Allwinner A64
Currently the AHB1 clock speed is configured as 200MHz by
the SPL, but this causes a subtle and hard to reproduce data
corruption in SRAM C (for example, this can't be easily
detected with a trivial memset/memcmp test).

For what it's worth, the Allwinner's BSP configures AHB1
as 200MHz, as can be verified by running the devmem2 tool
in the system running the Allwinner's kernel 3.10.x:

   0x1C20028: PLL_PERIPH0_CTRL_REG = 0x90041811
   0x1C20054: AHB1_APB1_CFG_REG    = 0x3180
   0x1C20058: APB2_CFG_REG         = 0x1000000
   0x1C2005C: AHB2_CFG_REG         = 0x1

However the FEL mode uses more conservative settings (100MHz
for AHB1):

   0x1C20028: PLL_PERIPH0_CTRL_REG = 0x90041811
   0x1C20054: AHB1_APB1_CFG_REG    = 0x3190
   0x1C20058: APB2_CFG_REG         = 0x1000000
   0x1C2005C: AHB2_CFG_REG         = 0x0

It is yet to be confirmed whether faster AHB1/AHB2 clock settings
can be used safely if we initialize the AXP803 PMIC instead of
using reset defaults. But in order to resolve the data corruption
problem right now, it's best to downclock AHB1 to a safe level.

Note that this issue only affects the SPL, which is not fully
supported on Allwinner A64 yet and it should not affect the boot0
usage (unless somebody can confirm SRAM C corruption with the
boot0 too).

cdaa633fcf arm/arm64: implement a boot header capability
Some SPL loaders (like Allwinner's boot0, and Broadcom's boot0)
require a header before the actual U-Boot binary to both check its
validity and to find other data to load. Sometimes this header may
only be a few bytes of information, and sometimes this might simply
be space that needs to be reserved for a post-processing tool.

Introduce a config option to allow assembler preprocessor commands
to be inserted into the code at the appropriate location; typical
assembler preprocessor commands might be:
  .space 1000
  .word 0x12345678

Signed-off-by: Steve Rae <srae@broadcom.com>
Commit Notes:
Please note that the current code:
  start.S (arm64) and
  vectors.S (arm)
already jumps over some portion of data already, so this option basically
just increases the size of this region (and the resulting binary).

For use with Allwinner's boot0 blob there is a tool called boot0img[1],
which fills the header to allow booting A64 based boards.
For the Pine64 we need a 1536 byte header (including the branch
instruction) at the moment, so we add this to the defconfig.

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).

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.

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.

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.
