In m5208_sys_read(), we have a loop of n from 0 to 31, and we calculate (2u << n). For the n == 31 iteration this will shift off the top of the unsigned 32 bit integer. This is harmless, because we're going to stop the loop with n == 31 anyway, but we can avoid the error by using 64-bit arithmetic here. (The SDCS0 register is documented at https://www.nxp.com/docs/en/reference-manual/MCF5208RM.pdf section 18.4.5; we want the lower 5 bits to indicate the RAM size, where 31 == 4GB, 30 == 2GB, and so on down. As it happens, the layout of the mcf5208evb board memory map means it doesn't make sense to have more than 1GB of RAM in any case.)
