Deallocation was not possible before, but is now.

Also, fix a typo.

- A couple of fields have changed name:
reg_eth_rw_ga_lo.table -> tbl
reg_eth_rw_ga_hi.table -> tbl
reg_eth_rw_gen_ctrl.flow_ctrl_dis -> flow_ctrl

- Add some new register fields.
reg_eth_rw_gen_ctrl.gtxclk_out
reg_eth_rw_gen_ctrl.phyrst_n
reg_eth_rw_tr_ctrl.carrier_ext

- max_size in reg_eth_rw_rec_ctrl had the wrong size.

- Registers reg_eth_rw_mgm_ctrl and reg_eth_r_stat was reworked completely.

The old name "r" would quite often produce warnings when other
variables with the same name was shadowed. Rename it __x to
make it more unlikely to happen.

Both of these are implemented using cris_delay10ns().

This is done to avoid collision with linux/leds.h

Also, clean up some whitespace errors.

Also, fix some white space errors, and constify cpuinfo_op.

Also, fix some whitespace errors.

Using kmalloc instead of vmalloc solves the stability problems
experienced by some 100 LX products.

- Move alignment of init data to page size outside define CONFIG_BLK_DEV_INITRD
  This avoids oops due to memory on the same page as init data being freed.
- Change hardcoded page size to use macro from asm/page.h
- Add reserved memory via CONFIG_ETRAX_VMEM_SIZE.
- Use available defines for TEXT_TEXT and INITCALLS.
- Cleanup whitespace.

There is no need to do all this work if they share memory descriptors.
Also, fix some minor whitespace and long lines.

- Fix bug where allocated memory didn't account for alignment.
- Add support for ARTPEC-3
- Add module_init for crisv32_intmem_init.

- Remove unneded code for ETRAX FS and ARTPEC-3

- Slight tweaks, use $acr + addoq to propagate carry across the loop boundary.
- Better use of latency cycles.
- Remove duplicate folding of carry, it is not needed.

Implements cris_delay10ns.

- Clean up some formatting and whitespace.

These files are different for ETRAX FS and ARTPEC-3.

- Change include paths to machine specific headers (asm/arch/hwregs -> hwregs)
- Add cpu_possible_map as cpumask_t and export it.
- Drop struct pt_regs parameter from crisv32_ipi_interrupt.
- timer -> timer0

- 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.

- Update to work for ETRAX FS and ARTPEC-3

- Change all spin_lock/local_irq_save to spin_lock_irqsave.
- Change multiple returns in functions where we have a lock to goto out.
- Correct number of arguments to gpio_poll_timer_interrupt, gpio_pa_interrupt.
- Break out gpio_write logic to smaller functions to make it readable.
- In setget_input and setget_output, avoid extra if-indent level.
- Change name LED_* -> CRIS_LED_* to avoid name clash.
- Don't use braces around single statement ifs.
- Fix whitespace errors.
- Remove useless CVS id and log.

The CRIS v32 architectures have more gpio ports and built in PWM.

- CONFIG_ETRAXFS_SIM -> CONFIG_ETRAX_VCS_SIM
- ser_intr_mask.data_avail -> ser_intr_mask.dav

- Don't use SANITYCHECK(x) as a macro, test FAST_TIMER_SANITY_CHECKS with
  ifdef. This makes it possible for automatic indent etc to work.
- Correct some whitespace errors.
- Don't initialize static variable.

- Include pinmux.h from machine specific directory.
- Add some more symbols: crisv32_pinmux_alloc, crisv32_pinmux_dealloc_fixed,
  crisv32_io_get_name and crisv32_io_get
