SDRAM speed always defaults to 166kHz

[kethort]

The speed data type in the SdramInfo struct should be uint32_t.

If it's an int data type, the value of memClock in calcClocks is "negative" after this calculation:

uint32_t memClock = m_sdramInfo->speed * 1000;

And that forces memClock to default to 166000 no matter what value the speed is set to in the SdramInfo struct.

if (memClock > 166000)
     memClock = 166000;

Serial monitor before data type change:

Starting up...
memClock : 4294956224
memClock : 166000
Requested kHz: -11072
Actual kHz : 165000
PLL k : 1
PLL n : 32

Serial monitor after data type change:

Starting up...
memClock : 120000
memClock : 120000
Requested kHz: 120000
Actual kHz : 120000
PLL k : 1
PLL n : 23
