Use of data types

[Khushhua Mogambo]

Hi
  I starting to port Linux kernel to my companies new ARM based
SoC and development board.

Some of the regs is 16bits wide and some is 32bits width. I ask if
my using u16 and u32 in place of 'unsigned short' and 'unsigned int'
in the whole porting would be acceptable or not?

In different wording, using only u16 and u32 always is considered good
quality or bad?

many thanks.
