First, thanks for working on this. I have this on my list for quite a
long time, but struggled to find enough time to actually get it done.

You shouldn't remove the old driver before the new one is in place, as
this breaks the build in between the two patches.

Can you provide more information about the problem/crash you experience
and the platform you are working on?
Are you referring to the same issue as Ashish in this discussion here [1]?
There are two reasons why I'd like to avoid using the whole memory
mapped area for AHB access.
First, I'd like to keep the U-Boot driver as close as possible to the
Linux driver.
Second, the intention of the spi-mem layer is to abstract the flash
layer and therefore this driver should work independently of flash type
or size. With your version this wouldn't be the case if you connect a
flash that is bigger than the memory map for example.
Thanks,
Frieder
