That's not the case any more, after
make clean; make ti_am62x_sk_defconfig; make

I get:

 images]$ ls -l
...
-rw-r--r-- 1 ...    282545 Feb 15 21:24 tiboot3-am62x-gp-evm.bin
-rw-r--r-- 1 ...    285134 Feb 15 21:24 tiboot3-am62x-hs-evm.bin
-rw-r--r-- 1 ...    285134 Feb 15 21:24 tiboot3-am62x-hs-fs-evm.bin
-rw-r--r-- 1 ...    285134 Feb 15 21:24 tiboot3.bin

But, well, this seems to be an upstream change in U-Boot.

However, there seems to be no alternative to

BR2_TARGET_TI_K3_IMAGE_GEN_SECTYPE, after removal of 
boot/ti-k3-image-gen package. People with SK-AM62 will find
their boards silently broken (GP variants).
