91558c8153 arm: armv7: add us timer for bootstage
solve issue when bootstage is used with armV7 generic timer
first call of timer_get_boot_us() use the function get_timer()
before timer initialization (arch.timer_rate_hz = 0)
=> div by 0

Commit-notes

When I activate bootstage on ARMV7 architecture with platform
using the generic armv7 timer defined in file
./arch/arm/cpu/armv7m/timer.c

I have a issue because gd->arch.timer_rate_hz = 0

For me the get_timer() function should not used before timer_init
(which initialize gd->arch.timer_rate_hz) at least for the ARMV7
timer.

But in the init sequence, the first bootstage fucntion is called
before timer_init and this function use the timer function.

For me it is a error in the generic init sequence :
mark_bootstage is called before timer_init.

static init_fnc_t init_sequence_f[] = {
....
    arch_cpu_init_dm,
    mark_bootstage,        /* need timer, go after init dm */
...
#if defined(CONFIG_ARM) || defined(CONFIG_MIPS) || \
        defined(CONFIG_BLACKFIN) || defined(CONFIG_NDS32) || \
        defined(CONFIG_SPARC)
    timer_init,        /* initialize timer */
#endif
.......

To solve the issue for all the paltform, we can move timer_init()
call just before mark_bootstage() in this array...

It should be ok for ARMV7 but I don't sure for other platform
impacted
- the other ARM platform or ARMV7 wich don't use generic timer
- MIPS BLACKFIN NDS32 or SPARC

and I don't sure of impact for other function called
(board_early_init_f for example....)

=> This patch solve issue only in timer armv7
   get_boot_us() can be called everytime without div by 0 issue
   (gd->arch.timer_rate_hz is not used)

beee6a3083 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:

ffff0040 <data_abort>:
ffff0040:       ebfffffe        bl      ffff0040 <data_abort>

ffff0044 <reset>:
ffff0044:       ea000012        b       ffff0094 <save_boot_params>

ffff0048 <save_boot_params_ret>:
ffff0048:       e10f0000        mrs     r0, CPSR
ffff004c:       e200101f        and     r1, r0, #31
ffff0050:       e331001a        teq     r1, #26

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.

1b42ab3eda ARM: DRA7: Fixup DSPEVE, IVA and GPU clock frequencies based on OPP
This patch adds support to update the device-tree blob to adjust the
DSP and IVA DPLL clocks pertinent to the selected OPP choice, with
the default being OPP_NOM. The voltage settings are done in u-boot,
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
   v2014.10 u-boot release. See commit, 02c41535b6 ("ARM: OMAP4/5:
   Remove dead code against CONFIG_SYS_CLOCKS_ENABLE_ALL").

The non-essential DPLLs are configured within the kernel during
the clock init step when parsing the device tree and creating
the clock devices. This approach meets both the u-boot and kernel

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.

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).

7f17fb7400 mx6: ddr: pass mx6_ddr_sysinfo to calibration routines
The DDR calibration routines have scattered support for bus
widths other than 64-bits:

-- The mmdc_do_write_level_calibration() routine assumes the
presence of PHY1, and
-- The mmdc_do_dqs_calibration() routine tries to determine
whether one or two DDR PHYs are active by reading MDCTL.

Since a caller of these routines must have a valid struct mx6_ddr_sysinfo
for use in calling mx6_dram_cfg(), and the bus width is available in the
"dsize" field, use this structure to inform the calibration routines which
PHYs are active.

This allows the use of the DDR calibration routines on CPU variants
like i.MX6SL that only have a single MMDC port.

2997ee5054 arm: sunxi: do not force USB for arch-sunxi
Currently, USB is forced-enabled for the sunxi familly, and there is no
way to disable it.

However, USB takes a long time to initiliase, delaying the boot by up to
5 seconds (without any USB device attached!). This is a very long delay,
especially in cases where USB booting is not wanted at all, and where
the device is expected to boot relatively often (even in production).

Change the way the dependencies are handled, by only forcibly selecting
USB when CONFIG_DISTRO_DEFAULTS ("defaults suitable for booting general
purpose Linux distributions") is set. This option defaults to y for the
sunxi familly, so the current default behaviour is kept unchanged. Users
interested in boot time and/or size will be able to disable this to
further disable USB.

With USB disabled, the time spent in U-Boot before handing control to
the Linux kernel is about 1s now, down from ~5s (Nanopi Neo, sunxi H3).

Remove the custom low-level initialization function and reuse the

ARMV8_MULTIENTRY config option to be enabled for Exynos7420.

On Exynos7420, the boot CPU belongs to the second cluster and so
with ARMV8_MULTIENTRY config option enabled, the 'branch_if_master'
macro fails to detect the CPU as boot CPU. As a temporary workaround
the CPU_RELEASE_ADDR is set to point to '_main'.

b7b8410a8f ls2080: Exit dpaa only right before exiting U-Boot
On ls2080 we have a separate network fabric component which we need to
shut down before we enter Linux (or any other OS). Along with that also
comes configuration of the fabric using a description file.

Today we always stop and configure the fabric in the boot script and
(again) exit it on device tree generation. This works ok for the normal
booti case, but with bootefi the payload we're running may still want to
access the network.

So let's add a new fsl_mc command that defers configuration and stopping
the hardware to when we actually exit U-Boot, so that we can still use
the fabric from an EFI payload.

For existing boot scripts, nothing should change with this patch.

a4d7d56037 ARM64: zynqmp: Support for multiple PM IDs assigned to a PM domain
Previously, it was assumed that there is a 1:1 mapping between
PM ID defined in the platform firmware and a PM domain. However, there
can be a situation where multiple PM IDs belong to a single PM domain
(e.g. PM IDs for GPU and two pixel processors correspond to a single
PM domain).

This patch adds support for assigning more than one PM ID to
a single PM domain.

Updated documentation accordingly.

Assigned pixel processors PM IDs to GPU PM domain.
