Like AM33xx and AM43xx, DRA7xx and AM57xx devices may need to have an non-standard boot address in memory. This may be due to the device being a high security variant, which place the Initial SoftWare (ISW) after certificates and secure software.
Allow these devices to set this from Kconfig.

Turns out this breaks OMAP3 among others as the question is asked there now and we have no default value (nor I suspect a reasonable one).
The only thing changed is ti_omap5_common.h, the default provided in that file is 0x40301350, would it be okay to just make that the default for ISW_ENTRY_ADDR for all platforms that included that file?
Well, ISW_ENTRY_ADDR doesn't make sense for OMAP3, right? I suspect the problem is that in moving it from mach-omap2/am33xx/Kconfig to mach-omap2/Kconfig you need to update the depends on guards so that it doesn't show up where it's not used.
CONFIG_SPL_TEXT_BASE should be converted to Kconfig, but cannot be right now due to some other platforms using strange methods for setting it in header files. So we have ISW_ENTRY_ADDR in Kconfig that is used to set CONFIG_SPL_TEXT_BASE. ISW_ENTRY_ADDR can be defined for any platform, I just may not be used depending on what headers it includes and whether they use it to set CONFIG_SPL_TEXT_BASE.
The change here is using it in ti_omap5_common.h, which a lot more platforms use is seems than I noticed. So all these platforms now need ISW_ENTRY_ADDR set to what the header to set them as (0x40301350).
Again, all this goes away when CONFIG_SPL_TEXT_BASE gets converted to Kconfig.
