33554fcec9 rockchip: rk3288: Fix wrong TPL_TEXT_BASE
TPL offset 0xff704004 is unaligned address which is adding nearest
8-bytes for next instruction, So  0xff704004 is adding 0x20 for
proper alignment which is causing the next instruction data
0xefffffff is moved.

Hexdump with overlaped bytes:
-----------------------------
0000000 0000 0000 0000 0000 0000 0000 0000 0000
0000010 0000 0000 0000 0000 0000 0000 ffff eaff

So, Fix the TEXT_BASE for proper aligned address 0xff704000

fa7b8eae7c arm64: show_regs: Dump the LRs HW values
These were dropped in [1], after relocation, for their values offset by
reloc_off.
Unconditionally show the HW values and add a '(reloc)' hint for the
offset values showed after relocation.
Also, the LRs' dumps are now formatted the same way the other regs' are.

5fbed8f2c6 ARM: Kconfig: Move TI_SECURE_DEVICE to a common area
TI_SECURE_DEVICE is used by both OMAP2+ and Keystone2 family devices,
and so when ARCH_OMAP2PLUS was used to gate off the OMAP2+ Kconfig
Keystone2 family devices lost this config option.

Move this option out of mach-omap2 Kconfig to a spot accessible by both
families. We picked arch/arm/Kconfig over the TI specific board/ti/
location as this option is not specific to our boards but rather our
architecture.

Plus at some point this option can be changed to just
SECURE_DEVICE, as having secure parts is not exclusive to TI and
so other vendors can interpret this option as needed by their device
configurations.

2faa1a302b mmc: omap_hsmmc: Workaround for errata id i802
According to errata i802, DCRC error interrupts
(MMCHS_STAT[21] DCRC=0x1) can occur during the tuning procedure.

The DCRC interrupt, occurs when the last tuning block fails
(the last ratio tested). The delay from CRC check until the
interrupt is asserted is bigger than the delay until assertion
of the tuning end flag. Assertion of tuning end flag is what
masks the interrupts. Because of this race, an erroneous DCRC
interrupt occurs.

The suggested  workaround is to disable DCRC interrupts during
the tuning procedure which is implemented here.

"ti,dual-volt" is used in linux kernel to set the voltage capabilities.
For host controller dt nodes that doesn't have "ti,dual-volt",
it's assumed 1.8v is the io voltage. This is not always true (like in
the case of beagle-x15 where the io lines are connected to 3.3v).
Hence if "no-1-8-v" property is set, io voltage will be set to 3v.

Standard features that can be disabled without breaking board support

- SYS_MMCSD_RAW_MODE_U_BOOT_USE_PARTITION: the boot rom supports a

IMAGE_SUBSYSTEM_SAL_RUNTIME_DRIVER does not exist in the specification

d1ceb0c488 imx: mx7: run sec_init for CAAM RNG
This patch adds a sec_init call into arch_misc_init(). Doing so in
conjunction with the patch "drivers/crypto/fsl: assign job-rings to
non-TrustZone" enables use of the CAAM in Linux when OPTEE/TrustZone is
active.

u-boot will initialise the RNG and assign ownership of the job-ring
registers to a non-TrustZone context. With recent changes by Lukas Auer to
fully initialize the RNG in sec_init() this means that u-boot will hand-off
the CAAM in a state that Linux then can use the CAAM without touching the
reserved DECO registers.

This change is safe both for the OPTEE/TrustZone boot path and the regular
non-OPTEE/TrustZone boot path.

when defining imx_iomux_v3_setup_pad().

The input keycode KEY_POWER is used in the imx6ull.dtsi file,
hence include the input header where used.

77e04034ec imx: mx25: Remove SION bit in all pin-mux that are safe
SION bit should be used in the situation that we need
to read back the value of a pin and should not be set by
default macro.

We get some malfunction as raised by following thread

https://www.spinics.net/lists/linux-usb/msg162574.html

As reported by this application note:
https://www.nxp.com/docs/en/application-note/AN5078.pdf

The software input on (SION) bit is an option to force an input
path to be active regardless of the value driven by the
corresponding module. It is used when the nature direction
of a pin depending on selected alternative function is an output,
but it is needed to read the real logic value on a pin.

The SION bit can be used in:
• Loopback: the module of a selected alternative function drives
the pad and also receives the pad value as an input
• GPIO capture: the module of a selected alternative function
drives the pin and the value is captured by the GPIO

SION bit is not necessary when the pin is configured as a peripheral
apart specific silicon bug. If an application needs to have this
set, this should be done in board file or in dts file

893d98d9aa ARM: dts: add pinmux and tuning settings for HS200/SDR104
The pinmux and tuning settings are from
https://source.codeaurora.org/external/imx/linux-imx/tree/arch/
arm/boot/dts/imx7s.dtsi?h=imx_4.9.11_1.0.0_ga
https://source.codeaurora.org/external/imx/linux-imx/tree/arch/
arm/boot/dts/imx7d-sdb.dts?h=imx_4.9.11_1.0.0_ga

To support HS200 and SDR104, we need change pinmux settings dynamically.
And configure tuning step and start tuning tap, otherwise you may
see tuning failure.

55e83d2e36 arm: imx: mx53loco: remove usage of mx53_dram_size
Static variables are not available during board_init_f().
'static uint32_t mx53_dram_size[2];' was used in board specific
dram_init(), dram_init_banksize() and get_effective_memsize() to avoid
multiple calls to get_ram_size().

Reused dram initialization functions from arch/arm/mach-imx/mx5/mx53_dram.c
