NXP FlexRAM on-chip ram controller
If the flexram,bank-spec property is specified, then the flexram will be
dynamically reconfigured to the configuration specified at runtime. An
example to configure the flexram dynamically using the
flexram,bank-spec property for rt1060 is as follows:

&itcm {
reg = < 0x0 DT_SIZE_K(64) >;
};
&dtcm {
reg = < 0x20000000 DT_SIZE_K(384) >;
};
&ocram {
reg = < 0x20280000 DT_SIZE_K(64) >;
};
&flexram {
flexram,bank-spec = <FLEXRAM_OCRAM>,
<FLEXRAM_OCRAM>,
<FLEXRAM_DTCM>,
<FLEXRAM_DTCM>,
<FLEXRAM_DTCM>,
<FLEXRAM_DTCM>,
<FLEXRAM_DTCM>,
<FLEXRAM_DTCM>,
<FLEXRAM_ITCM>,
<FLEXRAM_ITCM>,
<FLEXRAM_DTCM>,
<FLEXRAM_DTCM>,
<FLEXRAM_DTCM>,
<FLEXRAM_DTCM>,
<FLEXRAM_DTCM>,
<FLEXRAM_DTCM>;
};

This will configure the flexram for 384K of DTCM, 64K of ITCM,
and 64K of OCRAM.
