CRIS: Drop code related to obsolete or unused kconfigs

2015-11-02T19:03:05+00:00

Drop all code related to Kconfigs that don't exist.
Fix one Kconfig where it was actually typo:ed (ETRAX_KGB_PORT2)
Drop content related to CRIS v32 SoCs from etraxgpio.h headerfile,
all use of GPIO for both ETRAX FS and ARTPEC-3 should now be through
standard gpiolib instead.

cris: arch-v10: kgdb: Add '__used' for static variable is_dyn_brkp

2015-11-02T19:03:04+00:00

Within one C file, current gcc can optimize the global static variables
according to the C code, but it will skip assembly code -- it will pass
them to gas directly.

if the static variable is used between C code and assembly code in one C
file (e.g. is_dyn_brkp in kgdb.c), it needs '__used' to let gcc know it
should be still used, or gcc may remove it for optimization.

The related error in this case:

    LD      init/built-in.o
  arch/cris/arch-v10/kernel/built-in.o: In function `kgdb_handle_breakpoint':
  (.text+0x2aca): undefined reference to `is_dyn_brkp'

cris: arch-v10: kgdb: Use BAR instead of DTP0 for register P12

2015-11-02T19:03:04+00:00

For arch-v10, there is no DTP0 register, and at present, assembler know
BAR, so use BAR instead of DTP0, the related error (with allmodconfig):

cris: kgdb: use native hex2bin

2015-11-02T19:03:04+00:00

There are kernel native helpers to convert hex ascii to the binary format:
hex_to_bin() and hex2bin(). Thus, no need to reimplement them customly.

cris: don't use module_init for non-modular core eeprom.c code

2015-06-16T18:12:31+00:00

The eeprom.c code is compiled based on the Kconfig setting
ETRAX_I2C_EEPROM, which is bool.  So the code is either built in
or absent.  It will never be modular, so using module_init as an
alias for __initcall is rather misleading.

Fix this up now, so that we can relocate module_init from
init.h into module.h in the future.  If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.

Direct use of __initcall is discouraged, vs prioritized ones.
Use of device_initcall is consistent with what __initcall
maps onto, and hence does not change the init order, making the
impact of this change zero.   Should someone with real hardware
for boot testing want to change it later to arch_initcall or
something different, they can do that at a later date.

cris fasttimer: remove use of seq_printf return value

2015-04-15T23:35:25+00:00

The seq_printf return value, because it's frequently misused,
will eventually be converted to void.

See: commit 1f33c41c03da ("seq_file: Rename seq_overflow() to
     seq_has_overflowed() and make public")
