Add a CONFIG_CHECK_ECC_ERRORS define which causes the SDRAM POST and
mtest command to check for ECC errors during execution.
The 83xx, 85xx, and 86xx architectures currently support enabling
CONFIG_CHECK_ECC_ERRORS. Other architectures/boards can use it if they
implement an ecc_count() and ecc_info() function.
