ARM: socfpga: Add boot0 hook to prevent SPL corruption
Valid Altera SoCFPGA preloader image must contain special data at
offsets 0x40, 0x44, 0x48 and valid instructions at address 0x4c or
0x50. These addresses are by default used by U-Boot's vector table
and a piece of reset handler, thus a valid preloader corrupts those
addresses slightly. While this works most of the time, this can and
does prevent the board from rebooting sometimes and triggering this
issue may even depend on compiler.
The problem is that when SoCFPGA performs warm reset, it checks the
addresses 0x40..0x4b in SRAM for a valid preloader signature and
header checksum. If those are found, it jumps to address 0x4c or
0x50 (this is unclear). These addresses are populated by the first
few instructions of arch/arm/cpu/armv7/start.S:
Without this patch, the CPU will enter the code at 0xffff004c or
0xffff0050 , at which point the value of r0 and r1 registers is
undefined. Moreover, jumping directly to the preloader entry point
at address 0xffff0000 will also fail, because address 0xffff004.
is invalid and contains the preloader magic.
Add BOOT0 hook which reserves the area at offset 0x40..0x5f and
populates offset 0x50 with jump to the entry point. This way, the
preloader signature is stored in reserved space and can not corrupt
the SPL code.

This patch adds support to update the device-tree blob to adjust the

but the actual clock configuration itself is done in kernel because
of the following reasons:
1. SoC definition constraints us to NOT to do dynamic voltage
scaling ever after the initial avs0 setting in bootloader
- so the voltage must be set in bootloader.
2. The voltage level must be set even if the IP blocks like
GPU/DSP are unused.
3. The IVA, GPU and DSP DPLLs are not essential for u-boot functionality,
and similar DPLL clock configuration code has been cleaned up in

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.

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.

cmd: move CMD_PXE to Kconfig
Currently, CMD_PXE is forcibly enabled in config_distro_defaults.h, so
that general purpose distributions can rely on it being defined. This
header is included, under conditions or not, by various archs or
famillies of archs / SoCs.
However, it is very possible that boards based on those SoCs will not
have a physical ethernet connector at all, even if the have a MAC; for
example, the Nanopi Neo AIR (sunxi H3) does not. It is also possible
that network booting is absolutely not necessary for a device.
However, it is not possible to disable the PXE command, as it is
forcibly enabled and is non-configurable.
But it turns out we already have a config option to build a distro-ready
image, in the name of DISTRO_DEFAULTS.
Move CMD_PXE out of the hard-coded config_distro_defaults.h into a
Kconfig option, that gets selected by DISTRO_DEFAULTS when it is set.

Enable DISTRO_DEFAULT on platforms that missed it before
A number of platforms had been using the distro default feature before
it was moved to Kconfig but did not enable the new Kconfig option when
it was enabled. This caused a regression in terms of features and this
introduces breakage when more things move to Kconfig.
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).
