1d2c0506d3 mmc: move more driver config options to Kconfig
Move (and rename) the following CONFIG options to Kconfig:

  CONFIG_DAVINCI_MMC  (renamed to CONFIG_MMC_DAVINCI)
  CONFIG_OMAP_HSMMC   (renamed to CONFIG_MMC_OMAP_HS)
  CONFIG_MXC_MMC      (renamed to CONFIG_MMC_MXC)
  CONFIG_MXS_MMC      (renamed to CONFIG_MMC_MXS)
  CONFIG_TEGRA_MMC    (renamed to CONFIG_MMC_SDHCI_TEGRA)
  CONFIG_SUNXI_MMC    (renamed to CONFIG_MMC_SUNXI)

They are the same option names as used in Linux.

This commit was created as follows:

[1] Rename the options with the following command:

find . -name .git -prune -o ! -path ./scripts/config_whitelist.txt \
-type f -print | xargs sed -i -e '

s/CONFIG_SUNXI_MMC/CONFIG_MMC_SUNXI/g
'

[2] Commit the changes

[3] Create entries in driver/mmc/Kconfig.
    (copied from Linux)

[4] Move the options with the following command
tools/moveconfig.py -y -r HEAD \
MMC_DAVINCI MMC_OMAP_HS MMC_MXC MMC_MXS MMC_SDHCI_TEGRA MMC_SUNXI

[5] Sort and align drivers/mmc/Makefile for readability

509d4b9545 ARM64: zynqmp: Generate handoff structure for ATF
Xilinx ATF extending options for passing images from BL2(FSBL)
to BL31. U-Boot SPL is FSBL replacement that's why it should generate
handoff structure the same. Support only one entry which is U-Boot in
EL2 itself. When FIT image is adopted structure generate should be data
driven.

Currently ATF is placing this structure at the beggining of OCM which is
rewriting early parts of ATF which should be unused at that time.

83843c9b3a sunxi: A64: do an RMR switch if started in AArch32 mode
The Allwinner A64 SoC starts execution in AArch32 mode, and both
the boot ROM and Allwinner's boot0 keep running in this mode.
So U-Boot gets entered in 32-bit, although we want it to run in AArch64.

By using a "magic" instruction, which happens to be an almost-NOP in
AArch64 and a branch in AArch32, we differentiate between being
entered in 64-bit or 32-bit mode.
If in 64-bit mode, we proceed with the branch to reset, but in 32-bit
mode we trigger an RMR write to bring the core into AArch64/EL3 and
re-enter U-Boot at CONFIG_SYS_TEXT_BASE.
This allows a 64-bit U-Boot to be both entered in 32 and 64-bit mode,
so we can use the same start code for the SPL and the U-Boot proper.

We use the existing custom header (boot0.h) functionality, but restrict
the existing boot0 header reservation to the non-SPL build now. A SPL
wouldn't need such header anyway. This allows to have both options
defined and lets us use one for the SPL and the other for U-Boot proper.

Also add arch/arm/mach-sunxi/rmr_switch.S, which contains the original
ARM assembly code and instructions how to re-generate the encoded
version.

ce62e57fc5 ARM: boot0 hook: remove macro, include whole header file
For prepending some board specific header area to U-Boot images we
were so far including a header file with a macro definition containing
the actual header specification.
This works fine if there are just a few statements and if there is only
one alternative.
However adding more complex code quickly gets messy with this approach,
so let's just drop that intermediate macro and let the #include actually
insert the code directly.
This converts the callers and the callees, but doesn't change anything
at this point.

a5168a5900 armv8: move reset branch into boot hook
The boot0 hook we have so far is applied _after_ the initial branch
to the "reset" entry point. An upcoming change requires even this
branch to be changed, so we apply the hook macro at the earliest
point, and have the branch in the hook file as well.
This is no functional change at this point, just refactoring to simplify
upcoming patches.

15b505b055 arm: imx: add HAB authentication of image to SPL boot
When using HAB as secure boot mechanism on Wandboard, the chain of
trust breaks immediately after the SPL. As this is not checking
the authenticity of the loaded image before jumping to it.

The HAB status output will not be implemented in SPL as it adds
a lot of strings that are only required in debug cases. With those
it exceeds the maximum size of the available OCRAM (69 KiB).

The SPL MISC driver support must be enabled, so that the driver can use OTP fuse
to check if HAB is enabled.

085be482f6 ARM: revive CONFIG_USE_ARCH_MEMCPY/MEMSET for UniPhier and Tegra
Commit be72591bcd ("Kconfig: Move USE_ARCH_MEMCPY/MEMSET to
Kconfig") is misconversion.

The original logic in include/configs/uniphier.h was as follows:

  #if !defined(CONFIG_SPL_BUILD) && !defined(CONFIG_ARM64)
  #define CONFIG_USE_ARCH_MEMSET
  #define CONFIG_USE_ARCH_MEMCPY
  #endif

This means those configs were enabled when building U-Boot proper,
but disabled when building SPL.  Likewise for Tegra.

Now "depends on !SPL" prevents any boards with SPL support
from reaching these options.  This changed the behavior for
UniPhier and Tegra SoC family.

Please notice these two options only control the U-Boot proper
build.  As you see arch/arm/Makefile, ARM-specific memset/memcpy
are never compiled for SPL.  So, __HAVE_ARCH_MEMCPY/MEMSET should
not set for SPL.

Fixes: be72591bcd ("Kconfig: Move USE_ARCH_MEMCPY/MEMSET to Kconfig")

Add missing L3 cache flush functionality which absence prevents
Linux kernel from normal boot in case the L3 cache is enabled

The L3 cache is named the "last level" cache in order to keep
the terminology similar to the ATF code.
This cache should not be disabled by u-boot since the Linux
kernel cannot activate it, so it is activates at ATF stage.
However the cache flush is required for preventing data corruption
after disabling the MMU and the data cache before passing control
to the loaded Linux image.

fba82eb7c9 ARM: DRA7: Redefine voltage and efuse macros per OPP using Kconfig
Redefine the macros used to define the voltage values and the
efuse register offsets based on OPP for all the voltage domains.
This is done using Kconfig macros that can be set in a defconfig
or selected during a config step. This allows a voltage domain
to be configured/set to a corresponding voltage value depending
on the OPP selection choice.

The Kconfig choices have been added for MPU, DSPEVE, IVA and GPU
voltage domains, with the MPU domain restricted to OPP_NOM. The
OPP_OD and OPP_HIGH options will be added when the support for
configuring the MPU clock frequency is added. The clock
configuration for other voltage domains is out of scope in
u-boot code.

The CORE voltage domain does not have separate voltage values
and efuse register offset at different OPPs, while the MPU
voltage domain only has different efuse register offsets for
different OPPs, but uses the same voltage value. Any different
choices of OPPs for voltage domains on common ganged-rails
is automatically taken care to select the corresponding
highest OPP voltage value.

beb71279d8 ARM: OMAP4+: Add support for dynamically selecting OPPs
It can be expected that different paper spins of a SoC can have
different definitions for OPP and can have their own constraints
on the boot up OPP for each voltage rail. In order to have this
flexibility, add support for dynamically selecting the OPP voltage
based on the board to handle any such exceptions.

57de1ea5be arm: omap5: Add TEE loading support
secure_tee_install is used to install and initialize a secure TEE OS such as
Linaro OP-TEE into the secure world. This function takes in the address
where the signed TEE image is loaded as an argument. The signed TEE image
consists of a header (struct tee_header), TEE code+data followed by the
signature generated using image signing tool from TI security development
package (SECDEV). Refer to README.ti-secure for more information.

This function uses 2 new secure APIs.

1. PPA_SERV_HAL_TEE_LOAD_MASTER - Must be called on CPU Core 0. Protected
   memory for TEE must be reserved before calling this function. This API
   needs arguments filled into struct ppa_tee_load_info. The TEE image is
   authenticated and if there are no errors, the control passes to the TEE
   entry point.

2. PPA_SERV_HAL_TEE_LOAD_SLAVE - Called on other CPU cores only after
   a TEE_LOAD_MASTER call. Takes no arguments. Checks if TEE was
   successfully loaded (on core 0) and transfers control to the same TEE
   entry point.

The code at TEE entry point is expected perform OS initialization steps
and return back to non-secure world (U-Boot).

4c158b9a7d arm: omap5: Add function to make an SMC call on cpu1
On DRA7xx platform, CPU Core 1 is not used in u-boot. However, in some
cases it is need to make secure API calls from Core 1. This patch adds
an assembly function to make a secure (SMC) call from CPU Core #1.

3891a54f47 ARM: DRA7x/AM57xx: Get rid of CONFIG_AM57XX
CONFIG_AM57XX is just an unnecessary macro that is redundant given So,
remove the same instead of spreading through out the u-boot source
code and getting in the way to maintain common code for DRA7x family.
