Hello Mark

I have a question about your patch related to FIX_P*D mapping.
(f4710445458c0a1bd1c3c014ada2e7d7dc7b882f)

I understand it maps using bm_p*d to mapping FIX_P*D in
fixmap_remap_fdt().
But in early_fdt_map(), we already maps all fixmap region using bm_p*d.

My question is, 'Do we really need using FIX_P*D to remap the FIX_FDT?'.
My guess is that it uses a previously written function. Functianlly,
nothing has changed.

I think we can just use bm_p*d, then it can save the time mapping
FIX_P*D.

Could I get your opinion about this?

Regards,
Daero Lee
