aa36c84edf powerpc/mpc85xx: T104x: Add nand secure boot target
For mpc85xx SoCs, the core begins execution from address 0xFFFFFFFC.
In non-secure boot scenario from NAND, this address will map to CPC
configured as SRAM. But in case of secure boot, this default address
always maps to IBR (Internal Boot ROM).
The IBR code requires that the bootloader(U-boot) must lie in 0 to 3.5G
address space i.e. 0x0 - 0xDFFFFFFF.

For secure boot target from NAND, the text base for SPL is kept same as
non-secure boot target i.e. 0xFFFx_xxxx but the SPL U-boot binary will
be copied to CPC configured as SRAM with address in 0-3.5G(0xBFFC_0000)
As a the virtual and physical address of CPC would be different. The
virtual address 0xFFFx_xxxx needs to be mapped to physical address
0xBFFx_xxxx.

Create a new PBI file to configure CPC as SRAM with address 0xBFFC0000
and update DCFG SCRTACH1 register with location of Header required for
secure boot.

The changes are similar to
commit 467a40dfe3
    powerpc/mpc85xx: SECURE BOOT- NAND secure boot target for P3041

While P3041 has a 1MB CPC and does not require SPL. On T104x, CPC
is only 256K and thus SPL framework is used.
The changes are only applicable for SPL U-Boot running out of CPC SRAM
and not the next level U-Boot loaded on DDR.

8f01397ba7 powerpc/mpc85xx: SECURE BOOT- Enable chain of trust in SPL
As part of Chain of Trust for Secure boot, the SPL U-Boot will validate
the next level U-boot image. Add a new function spl_validate_uboot to
perform the validation.

Enable hardware crypto operations in SPL using SEC block.
In case of Secure Boot, PAMU is not bypassed. For allowing SEC block

2a5f7f2074 ARM: tegra: pick up actual memory size
On Tegra186, U-Boot is booted by the binary firmware as if it were a
Linux kernel. Consequently, a DTB is passed to U-Boot. Cache the address
of that DTB, and parse the /memory/reg property to determine the actual
RAM regions that U-Boot and subsequent EL2/EL1 SW may actually use.

Given the binary FW passes a DTB to U-Boot, I anticipate the suggestion
that U-Boot use that DTB as its control DTB. I don't believe that would
work well, so I do not plan to put any effort into this. By default the
FW-supplied DTB is the L4T kernel's DTB, which uses non-upstreamed DT
bindings. U-Boot aims to use only upstreamed DT bindings, or as close as
it can get. Replacing this DTB with a DTB using upstream bindings is
physically quite easy; simply replace the content of one of the GPT
partitions on the eMMC. However, the binary FW at least partially relies
on the existence/content of some nodes in the DTB, and that requires the
DTB to be written according to downstream bindings. Equally, if U-Boot
continues to use appended DTBs built from its own source tree, as it does
for all other Tegra platforms, development and deployment is much easier.

d0f45000ba ARM: tegra: unify Tegra186 Makefile a bit
Many files in arch/arm/mach-tegra are compiled conditionally based on
Kconfig variables, or applicable to all platforms. We can let the main
Tegra Makefile handle compiling (or not) those files to avoid each SoC-
specific Makefile needing to duplicate entries for those files. This
leaves the SoC-specific Makefiles to compile truly SoC-specific code.

In the future, we'll hopefully add Kconfig variables for all the other
files, and refactor those files, and so reduce the need for SoC-specific
Makefiles and/or ifdefs in the Makefiles.

So far, the framework support only FIT format image, and need to define

the name of property for the raw secure firmware image in that config.
The FIT image should be stored in Byte accessing memory, such as NOR

980d6a5511 ARM: Add an empty secure stack section
Until now we've been using memory beyond psci_text_end as stack space
for the secure monitor or PSCI implementation, even if space was not
allocated for it.

This was partially fixed in ("ARM: allocate extra space for PSCI stack
in secure section during link phase"). However, calculating stack space
from psci_text_end in one place, while allocating the space in another
is error prone.

This patch adds a separate empty secure stack section, with space for
CONFIG_ARMV7_PSCI_NR_CPUS stacks, each 1 KB. There's also
__secure_stack_start and __secure_stack_end symbols. The linker script
handles calculating the correct VMAs for the stack section. For
platforms that relocate/copy the secure monitor before using it, the
space is not allocated in the executable, saving space.

For platforms that do not define CONFIG_ARMV7_PSCI_NR_CPUS, a whole page
of stack space for 4 CPUs is allocated, matching the previous behavior.

Page align the secure section only when CONFIG_ARMV7_SECURE_BASE is not

320e0570e6 sunxi: FEL - Add the ability to recognize and auto-import uEnv-style data
The patch converts one of the "reserved" fields in the sunxi SPL
header to a fel_uEnv_length entry. When booting over USB ("FEL
mode"), this enables the sunxi-fel utility to pass the string
length of uEnv.txt compatible data; at the same time requesting
that this data be imported into the U-Boot environment.

If parse_spl_header() in the sunxi board.c encounters a non-zero
value in this header field, it will therefore call himport_r() to
merge the string (lines) passed via FEL into the default settings.
Environment vars can be changed this way even before U-Boot will
attempt to autoboot - specifically, this also allows overriding
"bootcmd".

With fel_script_addr set and a zero fel_uEnv_length, U-Boot is
safe to assume that data in .scr format (a mkimage-type script)
was passed at fel_script_addr, and will handle it using the
existing mechanism ("bootcmd_fel").

19e99fb4ff sunxi: Support booting from SPI flash
Allwinner devices support SPI flash as one of the possible
bootable media type. The SPI flash chip needs to be connected
to SPI0 pins (port C) to make this work. More information is
available at:

    https://linux-sunxi.org/Bootable_SPI_flash

This patch adds the initial support for booting from SPI flash.
The existing SPI frameworks are not used in order to reduce the
SPL code size. Right now the SPL size grows by ~370 bytes when
CONFIG_SPL_SPI_SUNXI option is enabled.

While there are no popular Allwinner devices with SPI flash at
the moment, testing can be done using a SPI flash module (it
can be bought for ~2$ on ebay) and jumper wires with the boards,
which expose relevant pins on the expansion header. The SPI flash
chips themselves are very cheap (some prices are even listed as
low as 4 cents) and should not cost much if somebody decides to
design a development board with an SPI flash chip soldered on
the PCB.

Another nice feature of the SPI flash is that it can be safely
accessed in a device-independent way (since we know that the
boot ROM is already probing these pins during the boot time).
And if, for example, Olimex boards opted to use SPI flash instead
of EEPROM, then they would have been able to have U-Boot installed
in the SPI flash now and boot the rest of the system from the SATA
hard drive. Hopefully we may see new interesting Allwinner based
development boards in the future, now that the software support
for the SPI flash is in a better shape :-)

Testing can be done by enabling the CONFIG_SPL_SPI_SUNXI option
in a board defconfig, then building U-Boot and finally flashing
the resulting u-boot-sunxi-with-spl.bin binary over USB OTG with
a help of the sunxi-fel tool:

   sunxi-fel spiflash-write 0 u-boot-sunxi-with-spl.bin

The device needs to be switched into FEL (USB recovery) mode first.
The most suitable boards for testing are Orange Pi PC and Pine64.
Because these boards are cheap, have no built-in NAND/eMMC and
expose SPI0 pins on the Raspberry Pi compatible expansion header.
The A13-OLinuXino-Micro board also can be used.

086ec0e26d rockchip: sdram: Update the driver to support of-platdata
Add support for of-platdata with rk3288 SDRAM initr. This requires decoding
the of-platdata struct and setting up the device from that. Also the driver
needs to be renamed to match the string that of-platdata will search for.

The platform data is copied from the of-platdata structure to the one used
by the driver. This allows the same code to be used with device tree and

However this is annoying for tests, which may want to examine the state

6b6024eadb arm64: add better and more generic spin-table support
There are two enable methods supported by ARM64 Linux; psci and
spin-table.  The latter is simpler and helpful for quick SoC bring
up.  My main motivation for this patch is to improve the spin-table
support, which allows us to boot an ARMv8 system without the ARM
Trusted Firmware.

Currently, we have multi-entry code in arch/arm/cpu/armv8/start.S
and the spin-table is supported in a really ad-hoc way, and I see
some problems:

  - We must hard-code CPU_RELEASE_ADDR so that it matches the
    "cpu-release-addr" property in the DT that comes from the
    kernel tree.

  - The Documentation/arm64/booting.txt in Linux requires that
    the release address must be zero-initialized, but it is not
    cared by the common code in U-Boot.  We must do it in a board
    function.

  - There is no systematic way to protect the spin-table code from
    the kernel.  We are supposed to do it in a board specific manner,
    but it is difficult to predict where the spin-table code will be
    located after the relocation.  So, it also makes difficult to
    hard-code /memreserve/ in the DT of the kernel.

So, here is a patch to solve those problems; the DT is run-time
modified to reserve the spin-table code (+ cpu-release-addr).
Also, the "cpu-release-addr" property is set to an appropriate
address after the relocation, which means we no longer need the
hard-coded CPU_RELEASE_ADDR.

4b689f02ff dm: gpio: MPC85XX GPIO platform data support
Define a platform data structure for the MPC85XX GPIO driver to allow
use of the driver without device tree. Users should define the GPIO
blocks for their platform like this:
  struct mpc85xx_gpio_plat gpio_blocks[] = {
         {
                 .addr = 0x130000,
                 .ngpios = 32,
         },
         {
                 .addr = 0x131000,
                 .ngpios = 32,
         },
  };

  U_BOOT_DEVICES(my_platform_gpios) = {
         { "gpio_mpc85xx", &gpio_blocks[0] },
         { "gpio_mpc85xx", &gpio_blocks[1] },
  };

This is intended to build upon the recent submission of the base
MPC85XX driver from Mario Six. We need to use that new driver
without dts support and this patch gives us that flexibility.
This has been tested on a Freescale T2080 CPU, although only the first
GPIO block.

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

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.

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.

and what is especially important most of those cases won't be
related to DMAed data to or from peripherals, i.e. we'll be doing

Given that IOC engine only snoops data that goes through DMA
we need to care ourselves about data used only by CPU cores
and so remove dependency on IOC from invalidate_dcache_all()
and always do real invalidation.

b5bd09820c arm: Allow skipping of low-level init with I-cache on
At present CONFIG_SKIP_LOWLEVEL_INIT prevents U-Boot from calling
lowlevel_init(). This means that the instruction cache is not enabled and
the board runs very slowly.

What is really needed in many cases is to skip the call to lowlevel_init()
but still perform CP15 init. Add an option to handle this.

d8906c1f3f x86: Probe pinctrl driver in cpu_init_r()
At present pinctrl driver gets probed in ich6_gpio driver's probe
routine, which has two issues:

 - Pin's PADs only gets configured when GPIO driver is probed, which
   is not done by default. This leaves the board in a partially
   functional state as we must initialize PADs correctly to get
   perepherals fully working.
 - The probe routine of pinctrl driver is called multiple times, as
   normally there are multiple GPIO controllers. It should really
   be called just once.

Move the call to syscon_get_by_driver_data() from ich6_gpio driver
to cpu_init_r().

f7a01e4848 x86: baytrail: Configure card detect pin of the SD controller
As of today, the latest version FSP (gold4) for BayTrail misses the
PAD configuration of the SD controller's Card Detect signal. The
default PAD value for the CD pin sets the pin to work in GPIO mode,
which causes card detect status cannot be reflected by the Present
State register in the SD controller (bit 16 & bit 18 are always zero).

Add a configuration for this pin in the pinctrl node.

Note I've checked the PAD configuration for all the pins in all the
3 controllers (eMMC/SDIO/SD). Only this SDMMC3_CD_B pin does not get
initialized to correct mode by FSP. With fsp,emmc-boot-mode set to
2 (eMMC 4.1), eMMC pins are initialized to func 1, but if we set
fsp,emmc-boot-mode to 1 (auto), those pins are initialized to func 3
which is correct according to datasheet.

58d1fedb1f x86: baytrail: Change fsp, emmc-boot-mode to "auto"
At present all BayTrail boards configure fsp,emmc-boot-mode to 2,
which means "eMMC 4.1" per FSP documentation. However, eMMC 4.1
only shows up on some early stepping silicon of BayTrail SoC.
Newer stepping SoC integrates an eMMC 4.5 controller. Intel FSP
provides a config option fsp,emmc-boot-mode which tells FSP which
eMMC controller it initializes. Instead of hardcoded to 2, now
we change it to 1 which means "auto".

With this change, MinnowMax board (with a D0 stepping BayTrail SoC)
can see the eMMC 4.5 controller at PCI address 00.17.00 via U-Boot
'pci' command.

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

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.

07d31f8f98 dm: gpio: Add driver for MPC85XX GPIO controller
This patch adds a driver for the built-in GPIO controller of the MPC85XX
SoC (probably supporting other PowerQUICC III SoCs as well).

Each GPIO bank is identified by its own entry in the device tree, i.e.

gpio-controller@fc00 {
      #gpio-cells = <2>;
      compatible = "fsl,pq3-gpio";
      reg = <0xfc00 0x100>
}

By default, each bank is assumed to have 32 GPIOs, but the ngpios
setting is honored, so the number of GPIOs for each bank in configurable
to match the actual GPIO count of the SoC (e.g. the 32/32/23 banks of
the P1022 SoC).

The usual functions of GPIO drivers (setting input/output mode and output
value setting) are supported.

The driver has been tested on MPC85XX, but it is likely that other
PowerQUICC III devices will work as well.
