Carles Cufi 33d17497d2 drivers: uart_nrf5: Use MDK baudrate divisor constants
The baudrate calculation present in set_baudrate() is
causing the UART to emit inital bytes incorrectly, for a
reason currently unknown, but directly related to the fact
that __aeabi_uldivmod is being invoked.
Since the nRF5x Product Specifications do not provide a
standard formula to calculate baudrates and instead list
a predefined set of divisor values, we opt here to use the
official values and remove the attempt at calculating them
manually.

Kumar Gala bbf736cf6e build: refactor kernel hex build to be common
Several platforms utilize a ihex image format.  Rather than
duplicating the build bits in everyones makefile, pull it into the
toplevel makefile so we all share it.

Ricardo Salveti 1dd18c3f92 arm: Add initial support for Nordic Semiconductor nRF51 series
Still missing a working timer driver, as SysTick is not really available
in this SoC series (enabled to avoid build issues, but not used).

Ricardo Salveti 69b9451af1 arm/nordic: use a common header for the nrf51/nrf52 SoC families
Integrating the IRQ definitions for both nRF51 and nRF52, and defining
the set of IRQ values that are common to both.

Also switch the controller, uart and clock drivers to use the common
header definitions.

Vinayak Chettimada 5732ae1ae0 arm: nordic_nrf5: Select clock control for BLE controller
Bluetooth controller implementation requires the low power
oscillator for radio time space scheduling and as sleep
clock; the high frequency oscillator as the active clock.

For Nordic Semiconductor's nRF5 Series SoC's select the
NRF Clock peripheral when BLUETOOTH_CONTROLLER is selected
in Kconfig build.

Daniel Thompson de2be17fee arm/nrf52: Set CPU_HAS_FPU
Quoting the product specification this device contains an "ARM
Cortex-M4 processor with floating-point unit" or, as this would
more normally be expressed an ARM Cortex-M4F.

Update Kconfig accordingly.

Vinayak Chettimada ad0e041e3d soc: Use nrf.h instead of nrf52.h and nrf52_bitfields.h
Since nrf.h abstracts the differences between the nRF51 and nRF52
architectures and chooses the right headers to include, it is
safer to use that instead of directly including the soc-specific
headers.

Inaky Perez-Gonzalez 60f5c97dd0 doc|config: Nordic RF5 fix references to SOC_NRF5
There was a reference to SOC_FAMILY_NRF5 which was not use by anyone
else and it seemes like it was a typo, where the right reference was
to symbol SOC_NRF5. However, the right fix is to move both sites to
use SOC_FAMILY_NRF5 *and* fix the SOC_SERIES to be only nrf52,
otherwise it causes path duplication and the build fails.

This was also causing documentation warnings that are thus killed.

Kumar Gala bbe222cad0 soc: arm: Unify setting of Cortex-M specifc compiler flags
Moved setting of specific Cortex-M compiler flags in each SoC directory
unify setting them in the arch/arm/soc Makefile.

Add flags for Cortex M0, M0+, M1, M3, M4, and M7.  However only
CONFIG_CPU_CORTEX_M3 and CONFIG_CPU_CORTEX_M4 are supported at this time

As part of this change converted Kbuild files for some SoCs into
Makefiles as the Makefiles would be empty otherwise.
