Please stop including (and remove) the meta-ti-bsp: from the subject.
It needlessly increases the verbosity of the commit message.

I don't like seeing the same big lists repeated over and over. I'd
prefer if you created a new variable and then used that to set the
SRC_URI for the three platforms:
JACINTO_LPM_PATCHES = "\
file://0001-feat-k3-choose-cluster_start_id-depending-on-the-soc.patch \
file://0002-feat-ti-add-message-to-encrypt-tfa-during-suspend.patch \
file://0003-feat-k3-handle-suspend-in-case-of-LPM_BOARDCFG_MANAG.patch \
"
SRC_URI:append:j7200 = " ${JACINTO_LPM_PATCHES}"
SRC_URI:append:j742s2 = " ${JACINTO_LPM_PATCHES}"
SRC_URI:append:j784s4 = " ${JACINTO_LPM_PATCHES}"
Feel free to pick a different variable name of course, just something
unique and descriptive.
