2008-04-28siimage: coding style cleanup (take 2)Sergei Shtylyov
Fix 18 errors and several warnings given by checkpatch.pl: - use of C99 // comments; - trailing whitespace; - 'switch' and 'case' not at the same indentation level; - no space before the open parenthesis of the 'if' and 'switch' statements; - space between function name and open parenthesis (though I have introduced such warnins in some places since the code looks prettier with the spaces); - including <asm/io.h> instead of <linux/io.h>; - line over 80 characters. In addition to these changes, also do the following: - make the arrays in sil_set_pio_mode() 'static', and make the arrays in sil_set_dma_mode() 'static const'; - change the string of the 'if' statements into the 'switch' statement in sil_pata_udma_filter(); - drop the needless '==' operators from the 'if' statements where a condition is a mere bit test; - remove needless initializer for the 'tmp' variable in init_chipset_siimage(); - beautify groups of the variable initializers and assignment operators; - add new line after variable definitions; - remove new line between the comment and the statements it refers to; - remove needless curly braces and parentheses; - fix typos, capitalize acronyms, etc. in the comments...

2008-04-28[MIPS] Pb1200/DBAu1200: move platform code to its proper placeSergei Shtylyov
Since both the IDE interface and SMC 91C111 Ethernet chip are on-board devices, not SOC devices, move the platform device registration form the common to the board specific code. While at it, remove semicolon (which didn't break compilation only by chance) from the AU1XXX_ATA_DDMA_REQ macro and do some renaming: - change 'au1200_ide0_' variable name prefix to the mere 'ide_'; - change 'smc91x_' variable name prefix to 'smc91c111_' since that's the name of the chip used on the boards; - drop 'AU1XXX_' prefix from the names of macros describing IDE and Ethernet on-board devices; - change 'SMC91111_' to 'SMC91C111_', change 'IRQ' to 'INT' in the names of the macros describing the Ethernet chip for consistency with the IDE macros; - change 'ATA_' to 'IDE_' and 'OFFSET' to 'SHIFT' (since this value is indeed a shift count) in the names of the macros describing the IDE interface.
