* spl: dm: use CONFIG_IS_ENABLED to test for the DM optionPhilipp Tomsich2017-08-131-0/+13
| | | | | | | | | | | | | | Even though there's now a TPL_DM configuration option, the spl logic still checks for SPL_DM and thus does not pick up the proper config option. This introduces the use of CONFIG_IS_ENABLED(DM) in spl.c to always pick up the desired configuration option instead of having a hard-coded check for the SPL variant.

* avr32: Retire AVR32 for goodAndy Shevchenko2017-07-062-3/+3
| | | | | | | | | | | | | | AVR32 is gone. It's already more than two years for no support in Buildroot, even longer there is no support in GCC (last version is heavily patched 4.2.4). Linux kernel v4.12 got rid of it (and v4.11 didn't build successfully). There is no good point to keep this support in U-Boot either.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the system is running PSCI firmware, the System Reset function (func ID: 0x80000009) is supposed to be handled by PSCI, that is, the SoC/board specific reset implementation should be moved to PSCI. U-Boot should call the PSCI service according to the arm-smccc manner. The arm-smccc is supported on ARMv7 or later. Especially, ARMv8 generation SoCs are likely to run ARM Trusted Firmware BL31.

* linux/compat.h: Properly implement ndelay fallbackmario.six@gdsys.cc2016-11-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Commit c68c62 ("i2c: mvtwsi: Make delay times frequency-dependent") extensively used the ndelay function with a calculated parameter which is dependant on the configured frequency of the I2C bus. If standard speed is employed, the parameter is usually 10000 (10000ns period length for 100kHz frequency). But, since the arm architecture does not implement a proper version of ndelay, the fallback default from include/linux/compat.h is used, which defines every ndelay as udelay(1). This causes problems for slower speeds on arm, since the delay time is now 9us too short for the desired frequency, which leads to random failures of the I2C interface. To remedy this, we implement a proper, parameter-aware ndelay fallback for architectures that don't implement a real ndelay function.
