Check the S3C2440 Data Manual. We can see that the S3C2440 can address the 1g address range, but the S3C2440 has only 27 address lines. Theoretically, only the 27 power of 2 is equal to M. Through careful analysis, we can see that S3C2440 solves this problem through a bank. The S3C2440 has 8 memory banks and leads to 8 bank lines (corresponding to ngcs0 ~ Ngcs7), select and disable different memory through
