This simple PMU driver allows to tyrn power on and off for selected
devices. In particularly Intel Tangier needs to power on SDHCI
controllers in order to access to them during board initialization.
In the future it might be expanded to cover other Intel MID platforms,
that's why it's located under arch/x86/lib and called pmu.c.

Add a specific serial driver for Intel MID platforms.
It has special fractional divider which can be programmed via UART_PS,
UART_MUL, and UART_DIV registers.
The UART clock is calculated as
UART clock = XTAL * UART_MUL / UART_DIV
The baudrate is calculated as
baud rate = UART clock / UART_PS / DLAB
Initialize fractional divider correctly for Intel Edison platform.
For backward compatibility we have to set initial DLAB value to 16
and speed to 115200 baud, where initial frequency is 29491200Hz, and
XTAL frequency is 38.4MHz.

work is handled by the boot monitor and, depending on the keystone

The boot monitor acts as the gateway to these secure functions and the
boot monitor for secure devices is available as part of the SECDEV

Various commands to NAND flash results in the NAND flash becoming busy.
For those commands the SoC should wait until the NAND indicates it is
no longer busy before sending further commands. However, there is a delay
between the time the SoC sends its last command and when the NAND flash
sets its Ready/Busy Pin. This delay (tWB) must be respected or the SoC may
falsely assume the flash is ready when in reality it just hasn't had enough
time to indicate that it is busy.
Properly delaying by tWB is already done for nand_command/nand_command_lp
in nand_base.c including the version of it in the Linux kernel. Therefore,
this patch brings the handling of tWB delay inline to nand_base.c

Up till this commit passing NULL as input parameter was allowed, but not
handled properly.
When one passed NULL to one of this function parameters, the code was
executed causing data abort.
However, what is more interesting, the abort was not caught because of code
execution in HYP mode with masked CPSR A bit ("Imprecise Data Abort mask bit).
The TI's AM57xx SoC switch to HYP mode with A bit masked in lowlevel_init.S
due to SMC call. Such operation (by default) is performed in SoC ROM code.
The problem would pop up when one:
- Switch back to SVC mode after disabling LPAE support
- Somebody enables A bit (by executing cpsie a asm instruction)
and then the previously described exception would be caught.
