Commit bfb3409d676f ("imx: toradex/apalis-imx8: correct SCU API usage") made an incorrect logic change in the error code check of sc_misc_otp_fuse_read(): - if (scierr == SC_ERR_NONE) { + if (scierr) { /* QP has one A72 core disabled */ is_quadplus = ((val >> 4) & 0x3) != 0x0; } The other changes in this commit are correct. sc_misc_otp_fuse_read() returns 0 on a successful fuse read. This inversion causes board_mem_get_layout() to report incorrect RAM size. Go back the original error check logic to fix the problem.
