From Andreas Dannenberg (TI K3 architect) [1]:
"HS-FS should be the default for all TI AM6x devices. This is our
"production silicon" and what's used for (almost) all projects,
especially new projects. This being said having support for GP device
variants still is desirable for existing boards/projects, such as the
current BeaglePlay boards (amongst earlier version of TI starter kit
EVMs for AM6x)."
See further details on e2e Forum [2]:
"Unfortunately with this transition any existing GP device based AM62x
(and AM64x) boards will no longer boot with MMC/SD card images generated"
For such existing GP device based AM62x (and AM64x) boards, users have
to provide the tiboot3.bin name using BR2_TARGET_TI_K3_R5_LOADER_TIBOOT3_BIN.

Since all AM62 and AM64 defconfig has been updated to use binman
and ti-k3-image-gen has been removed, binman is now mandatory
for all TI K3 SoC. So remove BR2_TARGET_TI_K3_R5_LOADER_USE_BINMAN
option since since it can't be disabled anymore.
We can remove BR2_TARGET_TI_K3_R5_LOADER_USE_BINMAN without
legacy handling since this option is not part of any Buildroot
release.
While at it, add one more like to binman dependencies in comments.

Removing any explicit reference to the ti_am62x_sk_defconfig
configuration, the script can also be used by other configurations or at
least by ti_am64x_sk_defconfig.

The 2024.01 version of U-Boot for the am62x-sk board has introduced two
major changes:
- The device tree k3-am625-sk.dtb is no longer searched in /boot, but in
/boot/dtb/ti. Hence, the disabling of BR2_LINUX_KERNEL_INSTALL_TARGET
and the use of extlinux.conf for the proper loading of the device tree.
Furthermore, the parameter BR2_ROOTFS_POST_SCRIPT_ARGS was used to
auto-generate the extlinux.conf file so that developers can change the
kernel loading options by modifying the .config.
- U-Boot is capable of building tiboot3.bin using Binman. So it's no longer
necessary to use custom tools like ti-k3-image-gen.
- Use a custom tiboot3.bin since the default is "hs-fs",
but the ti_am62x_sk_defconfig expect the "gp" one
Tested on SK-AM62B-P1.

BR2_TARGET_UBOOT_NEEDS_TI_K3_DM option has been introduced initially to
support certain TI K3 devices such as AM62x and AM62Ax that require a
Device Manager (DM) firmware.
This option needs to be renamed to use a more generic name in order
to cover further TI K3 SoCs support along with the new u-boot binman
tool that will be added in followup patch. With binman enabled in
u-boot on TI K3 SoC, ti-k3-boot-firmware is needed at buildtime to
provide ti-sysfw (System Firmware) for all TI K3 SoC along with Device
Manager (DM) firmware for AM62x and AM62Ax devices.
With binman support enabled, we don't need to provide the path of the
Device Manager firmware anymore (see [2]).
We can remove DM="<DM firmware>.xer5f" from UBOOT_MAKE_OPTS.
It also means that we can also remove BR2_TARGET_UBOOT_TI_K3_DM_SOCNAME
used to define DM path.
DM=$(BINARIES_DIR)/ti-dm/$(UBOOT_TI_K3_DM_SOCNAME)/ipc_echo_testb_mcu1_0_release_strip.xer5f
For now, keep BR2_TARGET_UBOOT_TI_K3_DM_SOCNAME and DM only when
ti-k3-image-gen is used. We need to update ti_am62x_sk_defconfig
to use binman before removing them along with ti-k3-image-gen.

The patch removes the hash for version 2022.10 of ti-k3-r5-loader
(i. e. U-Boot). Instead, it is added to a custom hash file in the
global patch dir of the ti_am6{2,4]x_sk_defconfig configurations.

Using PLATFORM=k3 can leads to a runtime boot crash on some K3 SoC (e.g.
j721e) because the optee flavor is missing.
We could use BR2_TARGET_OPTEE_OS_PLATFORM=k3 and
BR2_TARGET_OPTEE_OS_PLATFORM_FLAVOR=am62x but we actually can use
BR2_TARGET_OPTEE_OS_PLATFORM=k3-am62x as explained in the optee-os
Makefile [1]:
# If $(PLATFORM) is defined and contains a hyphen, parse it as
# $(PLATFORM)-$(PLATFORM_FLAVOR) for convenience
This is how meta-ti set the optee-os platform:
meta-ti]$ git grep OPTEEMACHINE
meta-ti-bsp/conf/machine/am437x-hs-evm.conf:OPTEEMACHINE = "ti-am43xx"
meta-ti-bsp/conf/machine/am57xx-hs-evm.conf:OPTEEMACHINE = "ti-am57xx"
meta-ti-bsp/conf/machine/beagleplay.conf:OPTEEMACHINE = "k3-am62x"
meta-ti-bsp/conf/machine/dra7xx-hs-evm.conf:OPTEEMACHINE = "ti-dra7xx"
meta-ti-bsp/conf/machine/include/am62axx.inc:OPTEEMACHINE = "k3-am62x"
meta-ti-bsp/conf/machine/include/am62pxx.inc:OPTEEMACHINE = "k3-am62x"
meta-ti-bsp/conf/machine/include/am62xx.inc:OPTEEMACHINE = "k3-am62x"
meta-ti-bsp/conf/machine/include/am64xx.inc:OPTEEMACHINE = "k3-am64x"
meta-ti-bsp/conf/machine/include/am65xx.inc:OPTEEMACHINE = "k3-am65x"
meta-ti-bsp/conf/machine/include/j7200.inc:OPTEEMACHINE = "k3-j721e"
meta-ti-bsp/conf/machine/include/j721e.inc:OPTEEMACHINE = "k3-j721e"
meta-ti-bsp/conf/machine/include/j721s2.inc:OPTEEMACHINE = "k3-j784s4"

meta-ti-bsp/conf/machine/include/j784s4.inc:OPTEEMACHINE = "k3-j784s4"
meta-ti uses the OPTEEMACHINE to set optee-os platform [2].
