If the total combined required buffer sizes is larger than the size of IRAM, then SDRAM will be used instead. This can be enabled safely if the IRAM is not intended for other uses. config ARCH_LPC32XX_MII_SUPPORT bool "Check to enable MII support or leave disabled for RMII support" help Say Y here to enable MII support, or N for RMII support. Regardless of which support is selected, the ethernet interface driver needs to be selected in the device driver networking section. The PHY3250 reference board uses RMII, so users of this board should say N. endmenu endif
