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.

The 2024.01 version of U-Boot for the am64x-sk board has introduced two
major changes:
- The device tree k3-am642-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_am64x_sk_defconfig expect the "gp" one.

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=am64x but we actually can use
BR2_TARGET_OPTEE_OS_PLATFORM=k3-am64x 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/j722s.inc:OPTEEMACHINE = "k3-am62x"
meta-ti-bsp/conf/machine/include/j784s4.inc:OPTEEMACHINE = "k3-j784s4"
meta-ti uses the OPTEEMACHINE to set optee-os platform [2].
