Adding support for AM43xx secure devices require the addition
of some SOC specific config options like the amount of memory
used by public ROM and the address of the entry point of u-boot
or SPL, as seen by the ROM code, for the image to be built
correctly.
This mandates the addition of am AM43xx CONFIG option and the
ARM Kconfig file has been modified to source this SOC Kconfig
file. Moving the TARGET_AM43XX_EVM config option to the SOC
KConfig and out of the arch/arm/Kconfig.
Updating defconfigs to add the CONFIG_AM43XX=y statement and
removing the #define CONFIG_AM43XX from the header file.

Update more defconfigs
Replace CREATE_BOARD_SYMLINK with TI_I2C_BOARD_DETECT

Is this correct?
AFAIK AM33xx and AM43xx have gotten lumped together in several places
both in U-Boot as well as in the Linux Kernel due to similarities in
architecture allowing for code re-use, almost like a "platform" even
though of course those are two different devices. I suppose because
AM33xx devices were first that's how the folder got its name original
name.
If you look around in that folder and open some files you should see
some code such as in emif4.c where stuff is shared.
Ah, yes, thanks.

Thanks for your patchseries looks very interesting.
May you have patches for am335x ? I ask, because I have an am335x based
board, which also uses HS boot mode, so I can test your patches, and
we can may sync our work.
Generally speaking AM335x HS device support in public U-Boot is
currently not for us (us, meaning anybody including existing customers)
to publicly discuss but you can probably take a guess in which direction
things might go after these initial steps taken with Daniel's patch
series. If you have inputs/suggestions however please feel free to email
me directly and we can take it from there.
Ok, thanks.
