adf418d8c1 arm: mach-k3: security: Lower verbosity of cert message for GP
When we find a certificate on an image to be booted on a GP device we
print out a message explaining that the certificate is being skipped.
This message is rather long and is printed for every image. Shorten
the message and make the long version into a debug message.

b566f7d239 Merge patch series "Introduce ICSSG Ethernet driver"
MD Danish Anwar <danishanwar@ti.com> says:

Introduce ICSSG PRUETH support in uboot. The ICSSG driver is used in TI
AM654 SR2.0.

The ICSSG PRU Sub-system runs on EMAC firmware. This series Introduces
support for ICSSG driver in uboot.

This series has been tested on AM65x SR2.0, and the ICSSG interface is
able to ping / dhcp and boot kernel using tftp in uboot.

To use ICSSG2 ethernet, the ICSSG firmware needs to be loaded to PRU RPROC
cores and RPROC cores need to be booted with the firmware. This step is
done inside driver similar to kernel.

The remoteproc driver uses request_fw_into_buf() API from fs-loader driver
to load and start rproc with the required firmwares.

This series only introduces driver files. The device tree and config
changes to enable ICSSG driver will be introduced later.

737a668413 net: ti: icssg: Add ICSSG ethernet driver
This is the PRUSS Ethernet driver for TI AM654 SR2.0 and later SoCs with
the ICSSG PRU Sub-system running EMAC firmware. ICSSG Subsystem supports
two slices per instance. This driver caters to both slices / ports of
the icssg subsystem.

Since it is not possible for Ethernet driver to register more than one
port for a given instance, this patch introduces top level PRUETH as
UCLASS_MISC and binds UCLASS_ETH to individual ports in order to support
bringing up more than one Ethernet interface in U-Boot.

Since top level driver is UCLASS_MISC, board files would need to
instantiate the driver explicitly.

3206b77c84 arm: mach-k3: common: EFI loader map memory below ram top
During the boot, the EFI loader maps the memory from ram_top to ram_end
as EFI_BOOT_SERVICES_DATA. When LMB does boot_fdt_add_mem_rsv_regions()
to OPTEE, TFA, R5, and M4F DMA/memory "no-map" for the kernel it produces
the following error message:

ERROR: reserving fdt memory region failed (addr=9cb00000 size=100000 flags=4)
ERROR: reserving fdt memory region failed (addr=9cc00000 size=e00000 flags=4)

ERROR: reserving fdt memory region failed (addr=9e800000 size=1800000 flags=4)

To avoid this, don't flag with EFI_BOOT_SERVICES_DATA the memory from
ram_top to ram_end by the EFI loader.

5ed961094d arm: mach-k3: am625: Fixup a53 cpu frequency by speed grade
The maximum frequency of the A53 CPU on the AM62 depends on the speed
grade of the SoC. However, this value is hardcoded in the DT for all
AM62 variants, potentially causing specifications to be exceeded. Moreover,
setting a common lower frequency for all variants increases boot time.
To prevent these issues, modify the DT at runtime from the R5 core to
adjust the A53 CPU frequency based on its speed grade.

e6ea13eba9 arm: mach-k3: Fix config check for FS_LOADER
load_firmware() API calls fs-loader APIs and checks for CONFIG_FS_LOADER
before calling those APIs. The if check only checks for CONFIG_FS_LOADER
but not for CONFIG_SPL_FS_LOADER.

When CONFIG_FS_LOADER is enabled, load_firmware() API calls fs-loader APIs
but this is done at SPL stage and at this time FS_LOADER is not built yet
as a result we see below build error.

Fix this by modifying the if check to CONFIG_IS_ENABLED(FS_LOADER) instead
of IS_ENABLED(CONFIG_FS_LOADER) as the former will check for the
appropriate config option (CONFIG_SPL_FS_LOADER / CONFIG_FS_LOADER) based
on the build stage.

cc0f759ddc arm: mach-k3: Move DRAM address of ATF for AM62/AM62a
The current address of TF-A in DRAM is just below the 512MB address line.
This means if the DRAM in a system is 512MB then TF-A is right at the
end of memory which is often reused, for instance U-Boot relocates itself
here. If a system has less than 512MB then that system wouldn't work at
all as TF-A would fail to load.

To avoid the issues above, move TF-A to the start of DRAM, which doesn't
change from system to system.

As TF-A is position independent, this has no dependency on TF-A. We
also fixup DT as needed when TF-A address is moved, so this change also
has no dependency on Linux and is fully forward/backward compatible.

8b0fc29de0 arm: mach-k3: am62: Fixup TF-A/OP-TEE reserved-memory node in FDT
The address we load TF-A and OP-TEE to is configurable by Kconfig
CONFIG_K3_{ATF,OPTEE}_LOAD_ADDR, but the DT nodes reserving this memory
are often statically defined. As these binaries are dynamically loadable,
and in the case of OP-TEE may not even be loaded at all, hard-coding these
addresses is not a hardware description, but rather a configuration.

If the address that U-Boot loaded TF-A or OP-TEE does not match the
address in hard-coded in DT, then fix that node address. This also handles
the case when no reserved memory for these is provided by DT, which is
more correct as explained above.

Add this fixup function, and enable it for AM62.

72703c7a0d arm: mach-k3: Refactor QoS settings
Refactor common QoS code into a new common header file, and the soc
specific setup_qos functions into a common API.

Rename $(soc)_qos_count and $(soc)_qos_data variables to qos_count and
qos_data. When QoS settings of more SoCs are added, only one pair will
be defined at a time, based on the config SOC_K3_$(soc).

This refactoring has been done for 2 major purposes.

- The auto-generated $(soc)_qos_data.c and $(soc)_qos.h files cannot
  have any code that is specific to any bootloader. Those files have to
  remain agnostic of different bootloader implementations and their
  header files.

- The existing implementation was less than ideal and would have enabled
  multiple $(soc)_qos_count and $(soc)_qos_data variables for all SoC
  variants.

94cfc6fc96 arm: mach-k3: j721s2_init: Support less than max DDR controllers
The number of DDR controllers to be initialised and used should depend
on the device tree with the constraint of the maximum number of
controllers the device supports. Since J721S2 has multiple (2)
controllers, instead of hardcoding the number of probes, move to
depending on the device tree UCLASS_RAM nodes present.

073f4f10b9 Merge patch series "Move framebuffer reservation for SPL to RAM end"
Devarsh Thakkar <devarsht@ti.com> says:

Move video memory reservation for SPL at end of RAM so that it does
not interefere with reservations for next stage so that the next stage
need not have holes in between for passed regions and instead it can
maintain continuity in reservations.

Also catch the bloblist before starting reservations to avoid the same
problem.

While at it, also fill missing fields in video handoff struct before
passing it to next stage.

This is as per discussions at :

ba20b2443c arm: mach-k3: common: Reserve video memory from end of the RAM
Setup video memory before page table reservation using
"spl_reserve_video_from_ram_top" which ensures framebuffer memory gets
reserved from the end of RAM.

This is done to enable the next stage to directly skip the
pre-reserved area from previous stage right from the end of RAM without
having to make any gaps/holes to accommodate those regions which was the
case before as previous stage reserved region not from the end of RAM.

Use gd->ram_top instead of local ram_top and update gd->reloc_addr after
each reservation to ensure further regions are reserved properly.

mach-k3/am625_fdt.c does fdt fixup depending on fields in the device
identification register. Move the accessors to the device identification
register as inline functions into the am62_hardware.h header, so that
they can be used for other functionality.

22d238f25d arch: mach-k3: Fix incorrect mapping of higher DDR addresses as device memory
Entry for physical address 0x500000000 in memory map table for MMU
configuration is spilling over and inadvertently making DDR available at
higher address (above 4GB address space) get mapped as device memory
(nGnRnE).

Fix this by adjusting entry size. Tested on AM62A SK. Before this patch:

=> time crc32 0x881000000 0x20000000
crc32 for 881000000 ... 8a0ffffff ==> 7f34d7ca

time: 1 minutes, 14.716 seconds

After patch:

=> time crc32 0x881000000 0x20000000
crc32 for 881000000 ... 8a0ffffff ==> 7f34d7ca

time: 2.710 seconds
