574852a2a5 CRIS v32: Update signal handling in kernel/signal.c
- do_signal now returns void, and does not have the previous signal set
  as a parameter.
- Remove sys_rt_sigsuspend, we can use the common one instead.
- Change sys_sigsuspend to be more like x86, don't call do_signal here.
- handle_signal, setup_frame and setup_rt_frame now return -EFAULT
  if we've delivered a segfault, which is used by callers to perform
  necessary cleanup.
- Break long lines, correct whitespace and formatting errors.

7edf744053 CRIS v32: Update driver for RTC chip pcf8563.
- Moved all calls to register_chrdev to a function called by module_init.
- Added mutex locking.
- Added better error handling at start up.
- Added BIN_TO_BCD of the month value before it is saved to the RTC.
- Corrected the month value returned by pcf8563_readreg.
- Cache the voltage low value at driver init so the battery status
  information does not get 'accidentally' cleared when setting the RTC time.
- Removed obsolete CONFIG_ETRAX_RTC_READONLY
- Voltage low ioctl():s RTC_VLOW_RD -> RTC_VL_READ, RTC_VLOW_SET -> RTC_VL_CLR

5f526d1467 CRIS v10: Setup serial port 2 to avoid accidental TXD pulse on startup.
If serial port 2 is used, select it in R_GEN_CONFIG.
If serial port 2 is used, setup the control registers for the port.
This is done to avoid a pulse on the TXD line during start up,
which could disturb some units.

Also, remove useless CVS id and log.
