2140d6b0ff arch: arm: mach-k3: am642_init: Correct the function name spl_boot_mode() to spl_mmc_boot_mode()
Function spl_boot_mode() is called in common/spl/spl_mmc.c, to find the
boot mode for a given boot device. This function was renamed to
spl_mmc_boot_mode() by commit e97590654a.

Therefore, rename spl_boot_mode to spl_mmc_boot_mode.

Force the clk-k3 driver to probe early during R5 SPL boot to ensure the

99214c1f48 arm: mach-k3: introduce new config option for sysfw split
On J7 family of SoCs (J721E and J7200), sysfw is being split to be run
under two cores, TIFS portion on DMSC core, and DM firmware under MCU
R5. As MCU R5 is also used to run one phase of the bootloader, we must
prevent access from here towards sysfw services. To support this, add
new config option which can be used to detect presence of RM/PM sysfw
services.

26f32c32b2 configs: am64x_evm_*_defconfig: Rearrange the components in SRAM to satisfy the limitations for USB DFU boot mode
For USB DFU boot mode there is a limitation on the load address of boot
images that they have to be less than 0x70001000. Therefore, move the
SPL_TEXT_BASE address to 0x70000000.

Currently ATF is being loaded at 0x70000000, if the SPL is being loaded at
0x70000000 then ATF would overwrite SPL image when loaded. Therefore, move
the location of ATF to a latter location in SRAM, past the SPL image. Also
rearrange the EEPROM and BSS data on top of ATF.

Given below is the placement of various data sections in SRAM

669a03e0ff arm: mach-k3: am642_init: Do USB fixups to facilitate host and device boot modes
U-Boot either supports USB host or device mode for a node at a time in the
device tree nodes. To support both host and dfu bootmodes, dr_mode is set
to "peripheral" by default and then fixed based on the mode selected by
the boot mode config dip switches on the board.

This needs to happen before the cdns3 generic layer binds the usb device
to a host or a device driver. Therefore, use fdtdec_setup_board()
implementation to fixup the device tree property.

This commit does the same thing as Linux commit 33def8498fdd.

078332cee3 arm: mach-k3: am642: Shut down R5 core after ATF startup on A53
The AM642 SoCs use the Main R5FSS0 as a boot processor, and runs
the R5 SPL that performs the initialization of the System Controller
processor and starting the Arm Trusted Firmware (ATF) on the Arm
Cortex A53 cluster. The Core0 serves as this boot processor and is
parked in WFE after all the initialization. Core1 does not directly
participate in the boot flow, and is simply parked in a WFI.

Power down these R5 cores (and the associated RTI timer resources
that were indirectly powered up) after starting up ATF on A53 by
using the appropriate SYSFW API in release_resources_for_core_shutdown().
This allows these Main R5F cores to be further controlled from the
A53 to run regular applications.

35b65dd8ef reset: Remove addr parameter from reset_cpu()
Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to.  This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value.  Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.

Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g.  COLD vs WARM resets).  As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).

To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely.  Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.

This transformation was done with the following coccinelle patch:

    @@
    expression argvalue;
    @@
    - reset_cpu(argvalue)
    + reset_cpu()

    @@
    identifier argname;

Starting J7200 SoC, ROM supports for loading sysfw directly from boot
image. ROM passes this information on number of images that are loaded
to bootloader at certain location. Add support for storing this
information before it gets corrupted.

30de1ba0d3 arm: mach-k3: j7200: Add support for SOC detection
The J7200 SoC is a part of the K3 Multicore SoC architecture platform.
It is targeted for automotive gateway, vehicle compute systems,
Vehicle-to-Vehicle (V2V) and Vehicle-to-Everything (V2X) applications.
The SoC aims to meet the complex processing needs of modern embedded
products.

Some highlights of this SoC are:
* Dual Cortex-A72s in a single cluster, two clusters of lockstep
  capable dual Cortex-R5F MCUs and a Centralized Device Management and
  Security Controller (DMSC).
* Configurable L3 Cache and IO-coherent architecture with high data
  throughput capable distributed DMA architecture under NAVSS.
* Integrated Ethernet switch supporting up to a total of 4 external ports
  in addition to legacy Ethernet switch of up to 2 ports.
* Upto 1 PCIe-GEN3 controller, 1 USB3.0 Dual-role device subsystems,
  20 MCANs, 3 McASP, eMMC and SD, OSPI/HyperBus memory controller, I3C and
  I2C, eCAP/eQEP, eHRPWM among other peripherals.
* One hardware accelerator block containing AES/DES/SHA/MD5 called SA2UL
  management.

dc57a554a5 arm: mach-k3: sysfw-loader: Add support for rom loading sysfw image
Starting J7200 SoC, ROM supports for loading sysfw directly from boot
image. In such cases, SPL need not load sysfw from boot media, but need
to receive boot notification message from sysfw. So separate out
remoteproc calls for system controller from sysfw loader and just
receive the boot notification if sysfw is already loaded.

403fc5c9cf arm: mach-k3: am6_init: Do USB fixups to facilitate host and device boot modes
U-boot only supports either USB host or device mode for a node at a
time in dts. To support both host and dfu bootmodes, set "peripheral"
as the default dr_mode but fixup property to "host" if host bootmode
is detected.

This needs to happen before the dwc3 generic layer binds the usb device
to a host or device driver. Therefore, add an fdtdec_setup_board()
implementation to fixup the dt based on the boot mode.

Also use the same fixup function to set the USB-PCIe Serdes mux to PCIe
in both the host and device cases. This is required for accessing the
interface at USB 2.0 speeds.

f9916b6d3b armv7R: K3: am654: Use full malloc in SPL both pre and post reloc
In order to be able to use things like file system drivers early on in
SPL (before relocation) in a memory-constrained environment when DDR is
not yet available we cannot use the simple malloc scheme which does not
implement the freeing of previously allocated memory blocks. To address
this issue go ahead and enable the use of the full malloc by manually
initializing the required functionality inside board_init_f by creating
a full malloc pool inside the pre-relocation malloc pool.

864e285739 arm: mach-k3: Clean non-coherent lines out of L3 cache
When switching on or off the ARM caches some care must be taken to ensure
existing cache line allocations are not left in an inconsistent state.
An example of this is when cache lines are considered non-shared by
and L3 controller even though the lines are shared. To prevent these
and other issues all cache lines should be cleared before enabling
or disabling a coherent master's cache. ARM cores and many L3 controllers
provide a way to efficiently clean out all cache lines to allow for
this, unfortunately there is no such easy way to do this on current K3
MSMC based systems.

We could explicitly clean out every valid external address tracked by
MSMC (all of DRAM), or we could attempt to identify only the set of
addresses accessed by a given boot stage and flush only those
specifically. This patch attempts the latter. We start with cleaning the
SPL load address. More addresses can be added here later as they are
identified.

Note that we perform a flush operation for both the flush and invalidate
operations, this is not a typo. We do this to avoid the situation that
some ARM cores will promote an invalidate to a clean+invalidate, but only
emit the invalidation operation externally, leading to a loss of data.
