Are you sure about this ? I've briefly browsed through the commits
in ti-sgx-km, and I don't see anything about removing support for

However indeed there used to be a per-platform directory in


But it has now been replaced by a single folder omap_linux, in commit
5f8570e190b37e534c9195728812190ec999c9d5, which says:

commit 5f8570e190b37e534c9195728812190ec999c9d5

    km: Makefile cleanup
    This patch simplifies the omap makefile to improve readability.
    The makefile is used to build DRM-based SGX user modules for K4.x and
    AM3/4/5/6 SoC only and therefore there is no need to keep the unused
    environment variables and conditions in history.
    - Remove unsupported targets
    - Remove unused environment variables
    - Remove unused and/or dead conditions

There are still tests for various TARGET_PRODUCT values:

eurasia_km/eurasiacon/build/linux2/omap_linux/Makefile:ifneq ($(filter omap5uevm jacinto6evm,$(TARGET_PRODUCT)),)
eurasia_km/eurasiacon/build/linux2/omap_linux/Makefile:ifneq ($(filter ti654x,$(TARGET_PRODUCT)),)
eurasia_km/eurasiacon/build/linux2/omap_linux/Makefile:ifneq ($(filter ti335x ti437x,$(TARGET_PRODUCT)),)
eurasia_km/eurasiacon/build/linux2/omap_linux/Makefile: ifeq ($(TARGET_PRODUCT), ti437x)

Could you clarify why you think there is only support for AM335x left ?
