of _PTS is used by default).
s4_nonvs prevents the kernel from saving/restoring the
ACPI NVS memory during hibernation.
nonvs prevents the kernel from saving/restoring the
ACPI NVS memory during suspend/hibernation and resume.
sci_force_enable causes the kernel to set SCI_EN directly
on resume from S1/S3 (which is against the ACPI spec,
but some broken systems don't work without it).

/*
* LPC32XX CPU and system power management
*
* The LCP32XX has three CPU modes for controlling system power: run,
* direct-run, and halt modes. When switching between halt and run modes,
* the CPU transistions through direct-run mode. For Linux, direct-run
* mode is not used in normal operation. Halt mode is used when the
* system is fully suspended.
*
* Run mode:
* The ARM CPU clock (HCLK_PLL), HCLK bus clock, and PCLK bus clocks are
* derived from the HCLK PLL. The HCLK and PCLK bus rates are divided from
* the HCLK_PLL rate. Linux runs in this mode.
*
* Direct-run mode:
* The ARM CPU clock, HCLK bus clock, and PCLK bus clocks are driven from
* SYSCLK. SYSCLK is usually around 13MHz, but may vary based on SYSCLK
* source or the frequency of the main oscillator. In this mode, the
* HCLK_PLL can be safely enabled, changed, or disabled.
*
* Halt mode:
* SYSCLK is gated off and the CPU and system clocks are halted.
* Peripherals based on the 32KHz oscillator clock (ie, RTC, touch,
* key scanner, etc.) still operate if enabled. In this state, an enabled
* system event (ie, GPIO state change, RTC match, key press, etc.) will
* wake the system up back into direct-run mode.
*
* DRAM refresh
* DRAM clocking and refresh are slightly different for systems with DDR
* DRAM or regular SDRAM devices. If SDRAM is used in the system, the
* SDRAM will still be accessible in direct-run mode. In DDR based systems,
* a transistion to direct-run mode will stop all DDR accesses (no clocks).
* Because of this, the code to switch power modes and the code to enter
* and exit DRAM self-refresh modes must not be executed in DRAM. A small
* section of IRAM is used instead for this.
*
* Suspend is handled with the following logic:
* Backup a small area of IRAM used for the suspend code
* Copy suspend code to IRAM
* Transfer control to code in IRAM
* Places DRAMs in self-refresh mode
* Enter direct-run mode
* Save state of HCLK_PLL PLL
* Disable HCLK_PLL PLL
* Enter halt mode - CPU and buses will stop
* System enters direct-run mode when an enabled event occurs
* HCLK PLL state is restored
* Run mode is entered
* DRAMS are placed back into normal mode
* Code execution returns from IRAM
* IRAM code are used for suspend is restored
* Suspend mode is exited
