No, all of them.

By removing it i triggered one error which i don't really understand. It
will be great if you can help me.

By defaul kernel will do fallowing remapping, which will trigger:
"Unable to handle kernel paging request at virtual address c2802174"

phys addr     ioremap        range size
=======================================
0x80054000 -> c2800000 size: 0x200
0x80040000 -> c2802000 size: 0x204
0x80088000 -> c2808000 size: 0x4000


But if change second range from 0x204 to 0x4000, then it works fine.
0x80054000 -> c2800000 size: 0x200
0x80040000 -> c2808000 size: 0x4000
0x80088000 -> c2810000 size: 0x4000

Why?

The "why" is in the text from your oops dump.  That's precisely /why/ we
print that text - so that we know /why/ the fault happened.
