cris: Only build flash rescue image if CONFIG_ETRAX_AXISFLASHMAP is selected

2017-01-12T10:22:48Z

commit 328cf6927bb72cadefddebbc9a23c793108147a2 upstream. If CONFIG_ETRAX_AXISFLASHMAP is not configured, the flash rescue image object file is empty. With recent versions of binutils, this results in the following build error. cris-linux-objcopy: error: the input file 'arch/cris/boot/rescue/rescue.o' has no sections This is seen, for example, when trying to build cris:allnoconfig with recently generated toolchains. Since it does not make sense to build a flash rescue image if there is no flash, only build it if CONFIG_ETRAX_AXISFLASHMAP is enabled.

cris: buggered copy_from_user/copy_to_user/clear_user

2016-09-24T08:07:44Z

commit eb47e0293baaa3044022059f1fa9ff474bfe35cb upstream. * copy_from_user() on access_ok() failure ought to zero the destination * none of those primitives should skip the access_ok() check in case of small constant size.

cris: Drop reference to get_cmos_time()

2015-11-02T19:03:05Z

Function get_cmos_time() was removed with commit 657926a83df9 ("cris: time: Cleanup of persistent clock stuff"). The remaining reference to it may cause the following build error. arch/cris/kernel/built-in.o:(___ksymtab+get_cmos_time+0x0): undefined reference to `get_cmos_time' Makefile:946: recipe for target 'vmlinux' failed Fixes: 657926a83df9 ("cris: time: Cleanup of persistent clock stuff") Cc: Xunlei Pang Cc: Rabin Vincent Signed-off-by: Guenter Roeck Signed-off-by: Jesper Nilsson

CRIS: Drop code related to obsolete or unused kconfigs

2015-11-02T19:03:05Z

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.

- Remove update_persistent_clock(), as it does nothing now. - Remove read_persistent_clock(), let it fall back to the weak version. Cc: Mikael Starvik Cc: John Stultz Cc: Arnd Bergmann Signed-off-by: Xunlei Pang Acked-by: Rabin Vincent Signed-off-by: Jesper Nilsson

cris: re-use helpers to dump data in hex format

2015-11-02T19:03:05Z

There are native helpers such as print_hex_byte() and %*ph specifier to dump data in hex format. Re-use them instead of a custom approach. Signed-off-by: Andy Shevchenko Signed-off-by: Jesper Nilsson

CRIS v32: remove old GPIO and LEDs code

2015-11-02T19:03:05Z

Since we now have a gpiolib driver, remove this code: The gpio-etraxfs driver (along with things like gpio-keys-polled for polling support) replaces the GIO driver implementations in mach-a3 and mach-fs. The various generic external chip drivers replace the "virtual gpio" parts. The generic gpio-leds driver replaces the LED handling. Signed-off-by: Rabin Vincent Signed-off-by: Jesper Nilsson

CRIS v32: remove I2C bitbanging driver

2015-11-02T19:03:05Z

Now that we have a gpiolib GPIO driver, the generic i2c-gpio driver provides this functionality. Signed-off-by: Rabin Vincent Signed-off-by: Jesper Nilsson

CRIS v32: add ARTPEC-3 and P1343 device trees

2015-11-02T19:03:05Z

Add a device tree for the Axis P1343 with the ARTPEC-3 SoC and on-board LEDs and RTC. Signed-off-by: Rabin Vincent Signed-off-by: Jesper Nilsson

CRIS v32: dev88: add GPIO, LEDs, RTC, temp sensor

2015-11-02T19:03:04Z

Add the GPIO driver to the device tree and, using it, support for the LEDs and the RTC chip (via I2C-GPIO), as well as the temperature sensor (via SPI-GPIO). Signed-off-by: Rabin Vincent Signed-off-by: Jesper Nilsson
