static void sdram_disable_unaligned_support ( void  )

inlinestatic

Unaligned access is not supported.

static void sdram_enable_scrambling ( uint32_t  ul_key1, uint32_t  ul_key2  )

inlinestatic

Off-chip Memory Scrambling is enabled.

Parameters

ul_key1	Key Part 1.
ul_key2	Key Part 2.

static void sdram_enable_unaligned_support ( void  )

inlinestatic

Unaligned access is supported.

static void sdram_enter_deep_power_down ( void  )

inlinestatic

Enter SDRAM deep power down mode.

Note

This mode is unique to low-power SDRAM.
