Building the kernel for omap3530 (beagleboard) (overo gusmtix fire)

hello everyone and I wish you a good day!!

my question is in relation to the “overo gumstix fire” board that has the same processor as the “beagleboard” I have tried to build the kernel for this board following the tutorial: https://www.digikey.com/eewiki/display/linuxonarm/BeagleBoard but i can’t get or find the u-boot panch for the overo, as mentioned for beagleboard 0001-omap3_beagle-uEnv.txt-bootz-n-fixes.patch!!

Does anyone know how to make or build that patch, or where can I find it?

thank you!!
