[U-Boot] enabling MMU in U-Boot-2017.09

Hello Everyone,
I am using U-Boot-2017.09. I want to enable MMU before U-Boot loads uImage.
I googled it and I found one thread dated back in July 2010. this is the link https://lists.denx.de/pipermail/u-boot/2010-July/073510.html
Basically, it involved code change (enabling MMU in start.S and some other modifications).
Before walking down on that road described in that link, I want to know is there any configuration parameter with which I can achieve it easily in U-Boot-2017.09?
If not, then is there any document/ guide which I can follow for U-Boot-2017.09? I am using armv7 cpu.
Any help would be highly appreciated.
Thanks you, Harshad.

You did not specify which exact armv7 processor you are using, and what issues are you trying to fix. Please provide more details.

Hi Bin,
Thanks for your reply.
I am using acadia processor.
After Linux boots we are getting some problems in MMU path. Debugging that would be one way to move ahead.
However, I want to enable MMU in Uboot context to test MMU path to RAM.
Also, is there any document or README which will have all the available configuration options? README in the U-Boot-2017.09 do have some of the configuration options but I believe not all of them are included there.
Please, do let me know if you need more details. I am new to this community. Please, bare with me.
Thanks, Harshad.
