There are seeral reasons, the most prominent being 1) because it's simply not needed in 95% of all cases 2) because it's bad to distribute vital configuration information into several independent files and 3) because we're preparing the grounds for a Kconfig based setup so we want to have all config options controlled by a single mechanism (board config file).

Yes, I have already thought about it before I submit patches. The fact is that there is there are two DDR chips connected to CS0 and CS1 of MX53 on loco board, but each DDR chip is 512MB, but CS0 and CS1 can support up to 1GB, which means the memory space is not continuous, when set: gd->ram_size = get_ram_size((volatile void *)CONFIG_SYS_SDRAM_BASE, PHYS_SDRAM_1_SIZE + PHYS_SDRAM_2_SIZE); it will return the same as: gd->ram_size = get_ram_size((volatile void *)CONFIG_SYS_SDRAM_BASE, PHYS_SDRAM_1_SIZE); I think the gd->ram_size is just used for uboot, but dram_init_banksize will tell linux kernel about the real memory layout. If you still think that I really need fix it, I will do it. > > >> +int board_mmc_getcd(u8 *cd, struct mmc *mmc) >> +{ >> + struct fsl_esdhc_cfg *cfg = (struct fsl_esdhc_cfg *)mmc->priv; >> + >> + if (cfg->esdhc_base == MMC_SDHC1_BASE_ADDR) >> + *cd = mxc_gpio_get(77); /*GPIO3_13*/ >> + else >> + *cd = mxc_gpio_get(75); /*GPIO3_11*/ > > Is this just data or a device?

No. Wrong order. Please don't add to the mess and clean up later.

Please merge your other two patches for the LOCO board together - these other patches correct only some CONFIG_ in the board configuration file: mx53loco: set mmc env to MMC slot1 MX5: Enable flat-device-tree support on mx53 loco board Submit a single patch with already the correct configuration for the LOCO board.
