The old comment stated that it was "junk needed for the arch-independent code
but which we never use in the CRIS port", but this is no longer true.

- Change name of __smp_processor_id to raw_smp_processor_id.
- cpu_possible_map is no longer a define for phys_cpu_present_map,
  it is now a cpumask_t.

Also, remove useless CVS id tag.

Also, remove useless CVS id tag.

Fixed a bug where two interfaces using pins in the same pin group could
not be allocated at the same time even if there where no pin collisions.

Change all restore and returns into goto exit pattern.

Also, remove useless CVS id and correct chapter reference for ETRAX100LX
Designer's Reference in comment.

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.

Also, cleanup formatting and fix whitespace errors.

Don't return when we're inside local_irq_disable(), use goto exit instead.
Also, cleanup some whitespace errors.

- Remove useless CVS id tag.
- Remove no longer needed extern declarations for kgdb.

- Change C99 comment style to C89.

- Move local_irq_save to after possible return in console_write_direct.
- Remove old raw_printk hack, not needed anymore.
- Add watchdog handling.
- Make serial_driver use depend on CONFIG_ETRAX_SERIAL.
- Remove useless CVS log.

- Change RTC_VLOW_RD -> RTC_VL_READ, RTC_VLOW_SET -> RTC_VL_CLR
- Whitespace and formatting.

- Use mutex instead of spinlock, fixes kernel bugzilla report 8339.
- Make sure that pcf8563_init can be called multiple times but only setup once.
- Change RTC_VLOW_RD -> RTC_VL_READ, RTC_VLOW_SET -> RTC_VL_CLR
- Cache the voltage low value at driver init so the battery status
  information does not get 'accidentally' cleared when setting the RTC time.
- Add weekday handling.
- Correct leapyear handling to include 100 and 400 year exceptions.
- Correct whitespace and formatting errors.
- Remove useless CVS id tag.

- Set the variable first to zero after first setup, so we can
  stop multiple calls to i2c_init from trying to setup i2c.

- The last byte read by the master in an i2c transfer needs to
  be NACKed, not ACKed.

- Also, remove useless CVS log and CVS id tags.

- Remove useless CVS log and CVS id tags.
- Whitespace fix and remove C++ comment.

- Correct include path for sv_addr_ag.h, should be asm/arch/
- Fix some whitespace errors.
- Remove useless CVS id tag.

- Correct include path for sv_addr_ag.h, should be included from asm/arch/
- Remove useless CVS id tag.
- Correct whitespace errors and some formatting.

Replace EXTRA_CFLAGS with ccflags-y.
Change ASFLAGS and LDFLAGS into asflags-y and ldflags-y, we only need
these flags in this makefile.

Replace use of EXTRA_CFLAGS with ccflags-y and LDFLAGS with ldflags-y,
(we only need to change linker flags for this makefile)

- Shorten include paths to machine dependent header files.
- Register name for first timer is now regi_timer0.
- Remove raw_printk hack, use oops_in_progress instead.
- Add handling of CPU frequency scaling for CRIS.
- Remove regs parameter to timer_interrupt, get them from get_irq_regs instead.
- Whitespace and formatting changes.

- Shorten include paths for machine dependent header files.
- Add volatile to hardeware register pointers.
- Add spinlocks around critical region.
- Expand macros for handling of leds.

- Remove watchdog handling, handled elsewhere.
- Shorten include paths to machine dependent header files.
- Remove raw_printk hack, we now use oops_in_progress instead.
- Add handling of BUG for exception handlers (break 14).
- Formatting and whitespace changes.

- Shorten include paths for machine dependent header files.
- Remove unused extern declaration of etrax_gpio_wake_up_check.
- Register name for first timer is now regi_timer0.

- First timer register has changed name to timer0.
- Build IRQs with only IRQ number, mask bit will be calculated instead.
- Add more IRQs, up to 64 supported.
- Use arrays to hold which IRQs triggered instead of trying to do magic
  with two 32 bit values now that more than 32 IRQs are supported.
