RT86130 Two more files for the Linux LPC1788 SSP/SPI patch.

RT #82124 Ethernet in Linux for SF2-DEV-KIT BSP

RT #84677. ESDHC: use external DMA (DMAC channel) for xfers

We configure used DMAC channel src as 'Always enabled', and so
can't process the whole xfer chain in one transaction (which
could increate speed more).

RT #82414. M2S: musb driver cleanup (build warnings)

RT #81519. M2S: Change allowed spi speed to maximum.

RT80459 Move the SmartFusion I2C device driver to the kernel tree.

Add I2C-specific initialization code to the platform code.
Add kernel configuration for the I2C busses and devices.

RT79979. stm32 rtc: Support RTC in Linux STM32F2

 * Implement the part of RTC initialization code that is not tied
directly to the RTC register map (platform-specific initialization code)
in the function stm32_rtc_init() in arch/arm/mach-stm32/rtc.c. Call this
function from stm32_init().
 * The initialization code in stm32_rtc_init() consists of the
following operations:
    1. Enable the PWR MCU module to allow access to the RTC.
    2. Enable the LSE oscillator (a low-speed external oscillator).
           This oscillator runs at 32.768 kHz.
    3. Select the LSE at the source clock for the RTC.
    4. Enable the Real-Time Clock (if not yet running).

RT #80098. Added data synch barrier before "wfi" in cpu_v7m_do_idle().

WFI can go to the low power mode, so DSB added to ensure all cache and
memory accesses are completed. See proc-v7.S for reference.

RT #78101. Fixed the CONFIG_MODULES build for lpc1788_etc.c.

RT79297. serial: stm32_usart: Implement stm_port_set_termios()

 * Implemented stm_port_set_termios() to change in run-time the baudrate,
parity bit configuration and the number of stop bits.
 * Added parsing of console= options from kernel parameters to
stm_console_setup().
 * Maximum baud rate is calculated depending on the apb clock.
