6c6dc56c1e CRIS v32: Add support for ETRAX FS and ARTPEC-3 for arch-v32/hwregs/eth_defs.h
- 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.

8d07328744 CRIS v32: Rename variable used in macro for arch-v32/hwregs/dma.h
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.

baa69b121a CRIS v32: Fix startup oops and replace hardcoded pagesize in vmlinux.lds.S
- Move alignment of init data to page size outside define CONFIG_BLK_DEV_INITRD

- 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.

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
