Memory Controller Reset and Initialization
On reset, the SDRAM interface is disabled. Reset values for the boot ROM are determined by
BOOT_SEL (see the Intel® PXA27x Processor Family Developers Manual, Memory Controller
chapter). Boot ROM is immediately available for reading upon exit from reset, and all memory
interface control registers are available for writing.
On hardware reset, the memory pins and controller are in the state shown in
