TMS320F28374D: 库文件F2837xD_Gpio.c中GPIO初始化函数void InitGpio()的问题

How I understand it is that the first comment says that all GPIO pins are by default set to input with pull-ups enabled. The second comment seems to be referring to the fact that there's a way to avoid doing this for all pins, or a 'hack', which is for when the user maybe does not want pull-ups enabled by default. Looking at the code in the file, it seems you can change the default to something else within that for-loop. I have not tested it before, but that's what it appears to be.
