Subject[PATCH 01/47] Rearrange Kconfigs for CRIS v10 and v32 to allow compilation without warnings.
- Remove some unneeded configs and add some new ones.
- Merge common config items to common file instead of duplicating them.
- Pull in standard Kconfig.preempt.
- Remove some unneeded Kconfigs for subsystems not (yet) available on CRIS
(md, scsi, ieee1394, i2o, isdn, telephony, media, pcmcia, pci)
- Rename CRISv32 config items which had different types from CRISv10.
(ETRAX_LED2G, ETRAX_LED2R, ETRAX_LED3G, ETRAX_LED3R, ETRAX_I2C_DATA_PORT,
ETRAX_I2C_CLK_PORT)
