18cfa612a9 fit: Support compat string property in configuration node
This patch adds support for an optional optimization to compatible
string matching where the compatible string property from the root node
of the kernel FDT can be copied into the configuration node of the FIT
image. This is most useful when using compressed FDTs or when using FDT
overlays, where the traditional extraction of the compatible string from
the kernel FDT itself is not easily possible.

b1307f884a fit: Support compression for non-kernel components (e.g. FDT)
This patch adds support for compressing non-kernel image nodes in a FIT
image (kernel nodes could already be compressed previously). This can
reduce the size of FIT images and therefore improve boot times
(especially when an image bundles many different kernel FDTs). The
images will automatically be decompressed on load.

This patch does not support extracting compatible strings from
compressed FDTs, so it's not very helpful in conjunction with
CONFIG_FIT_BEST_MATCH yet, but it can already be used in environments
that select the configuration to load explicitly.

2090854cd2 common: Move bootm_decomp_image() to image.c (as image_decomp())
Upcoming patches want to add decompression to use cases that are no
longer directly related to booting. It makes sense to retain a single
decompression routine, but it should no longer be in bootm.c (which is
not compiled for all configurations). This patch moves
bootm_decomp_image() to image.c and renames it to image_decomp() in
preparation of those upcoming patches.

adc097e133 env: ti: boot: Use ttyS2 instead of ttyO2
ttyO2 console enables legacy CONFIG_SERIAL_OMAP driver in kernel.
Nowadays it's preferred to use the generic CONFIG_SERIAL_8250_OMAP
driver, which being enabled via ttyS2 console. Both drivers are enabled
in multi_v7_defconfig and in omap2plus_defconfig, for compatibility
reasons. Let's switch to ttyS2 console, to be sure that standard 8250
serial driver is used.

Similar behavior can be also achieved by enabling
CONFIG_SERIAL_8250_OMAP_TTYO_FIXUP option in kernel, but it's better not
to rely on that, as it can be disabled or removed after transitional
period.

Right now on DRA7/AM57x platforms the 8250-omap driver is being probed
first, and omap-serial driver is only probed if the first one failed.
It can be seen from uart3 definition in arch/arm/boot/dts/dra7-l4.dtsi:

    compatible = "ti,dra742-uart", "ti,omap4-uart";

So the kernel already uses 8250 driver. This change basically allows
kernel developers to throw away the omap-serial driver and associated
compatibility options. Similar discussions [1,2] have started several
years ago, so it should be safe to do that now.

6b66d2ee47 ARM: dts: am57xx: Disable voltage switching for SD card
If UHS speed modes are enabled, a compatible SD card switches down to 1.8V
during enumeration. If after this a software reboot/crash takes place and
on-chip ROM tries to enumerate the SD card, the difference in
IO voltages (host @ 3.3V and card @ 1.8V) may end up damaging the card.

The fix for this is to have support for power cycling the card in
hardware (with a PORz/soft-reset line causing a power cycle of the card).
Because the beaglebone X15 (rev A,B and C), am57xx-evms and am57xx-idks don't
have this capability, disable voltage switching for these boards.

The major effect of this is that the maximum supported speed mode is now
high speed(50 MHz) down from SDR104(200 MHz).

0a704924f3 armv7R: K3: j721e: Add support for boot device detection
J721E allows for booting from primary or backup boot media.
Both media can be chosen individually based on switch settings.
ROM looks for a valid image in primary boot media, if not found
then looks in backup boot media. In order to pass this boot media
information to boot loader, ROM stores a value at a particular
address. Add support for reading this information and determining
the boot media correctly.

c2562d7c9e arm: K3: j721e: Add basic support for J721E SoC definition
The J721E SoC belongs to the K3 Multicore SoC architecture platform,
providing advanced system integration to enable lower system costs
of automotive applications such as infotainment, cluster, premium
Audio, Gateway, industrial and a range of broad market applications.
This SoC is designed around reducing the system cost by eliminating
the need of an external system MCU and is targeted towards ASIL-B/C
certification/requirements in addition to allowing complex software
and system use-cases.

Some highlights of this SoC are:
* Dual Cortex-A72s in a single cluster, three clusters of lockstep
  capable dual Cortex-R5F MCUs, Deep-learning Matrix Multiply Accelerator(MMA),
  C7x floating point Vector DSP, Two C66x floating point DSPs.
* 3D GPU PowerVR Rogue 8XE GE8430
* Vision Processing Accelerator (VPAC) with image signal processor and Depth
  and Motion Processing Accelerator (DMPAC)
* Two Gigabit Industrial Communication Subsystems (ICSSG), each with dual
  PRUs and dual RTUs
* Two CSI2.0 4L RX plus one CSI2.0 4L TX, one eDP/DP, One DSI Tx, and
  up to two DPI interfaces.
* Integrated Ethernet switch supporting up to a total of 8 external ports in
  addition to legacy Ethernet switch of up to 2 ports.
* System MMU (SMMU) Version 3.0 and advanced virtualisation
  capabilities.
* Upto 4 PCIe-GEN3 controllers, 2 USB3.0 Dual-role device subsystems,
  16 MCANs, 12 McASP, eMMC and SD, UFS, OSPI/HyperBus memory controller, QSPI,
  I3C and I2C, eCAP/eQEP, eHRPWM, MLB among other peripherals.
* Two hardware accelerator block containing AES/DES/SHA/MD5 called SA2UL
  management.
* Configurable L3 Cache and IO-coherent architecture with high data throughput
  capable distributed DMA architecture under NAVSS
* Centralized System Controller for Security, Power, and Resource
  Management (DMSC)

54e4311fa1 remoteproc: k3_rproc: Rename to ti_k3_arm64_rproc
k3_rproc driver is specifically meant for controlling an arm64
core using TISCI protocol. So rename the driver, Kconfig symbol,
compatible and functions accordingly.

While at it drop this remoteproc selection for a53 defconfig.

4fa23ebe73 remoteproc: tisci: add TI-SCI processor control helper functions
Texas Instruments' K3 generation SoCs has specific modules/register
spaces used for configuring the various aspects of a remote processor.
These include power, reset, boot vector and other configuration features
specific to each compute processor present on the SoC. These registers
are managed by the System Controller such as DMSC on K3 AM65x SoCs.

The Texas Instrument's System Control Interface (TI-SCI) Message Protocol
is used to communicate to the System Controller from various compute
processors to invoke specific services provided by the firmware running
on the System Controller.

Add a common processor control interface header file that can be used by
multiple remoteproc drivers. The helper functions within this header file
abstract the various TI SCI protocol ops for the remoteproc drivers, and
allow them to request the System Controller to be able to program and
manage various remote processors on the SoC. The common macros required
by the R5 remoteproc driver were also added. The remoteproc drivers are
expected to manage the life-cycle of their ti_sci_proc_dev local
structures.

96f41f9cde cmd: remoteproc: Allow list command to print the probed devices
'rproc list' is currently allowed only after probing all the
available remoteproc devices. Given that 'rproc init' is updated
to probe and initialize devices individually, allow the 'rproc list'
command to print all probed devices at any point.
