[BOOTVID]
- Synchronize correctly arm/bootdata.c with i386, as it was done previously. - Code formatting: whitespace fixes, add braces/brackets and spaces where needed; comments styling. - Correctly put braces for casts and around macro parameters. - Add some IN/OUT. - Fix parameter names of a function. [INBV] - Fix parameter names of two functions. svn path=/trunk/; revision=64017
