If Davinci AEMIF is used we don't need to set timings and bus width.
It is done by AEMIF driver (drivers/memory/davinci-aemfi.c).

Instead above #if, just use a variable.
bool aemif = IS_ENABLED(CONFIG_TI_DAVINCI_AEMIF) and then skip
the below code. #if block in the middle of the code looks ugly.
Yes, this is the hack.
The problem is that this part of code contains the call of Davinci
platform function davinci_aemif_setup_timing() which is not accessible
if Kernel is built for Keystone only.
That's why "#if" has been used.
This part of code has to be removed together with Davinci aemif platform
code (aemif.c), once Davinci will be converted to DT and use
new driver.
The corresponding comment can be added here. Is it ok?
Other than that patch looks fine to me.

Santosh
