    cgtqmx6eval/cgtumx6: add defconfig files for manufacturing bootloader · cb2617e3

    Adds the default configuration files in order to build the manufacturing bootloaders
    for congatec i.MX6 based products (conga-QMX6, conga-UMX6).
    
    In order to build a suitable manufacturing bootloader for a specific partnumber, it is
    essential to choose the correct configuration file depending on product, memory size,
    memory frequency and bus width.
    
    For instance, if it's intended to build a manufacturing bootloader for conga-QMX6/DCL-1G eMMC4
    (with congatec part number 016101) the board parameters are:
    
    product: QMX6 (i.e. the target board is cgtqmx6eval)
    memorysize: 1GByte (i.e. 1024 MByte)
    memory buswidth: 64bit (the congatec i.MX6 solo core products are connected via a 32bit memory interface, all others are using 64bit)
    memory frequency: 400MHz, respectively 396MHz (i.MX6 solo and dual core lite operates at 396MHz, i.MX6 dual and quad core at 528MHz)
    
    Therefore, the correct configuration file for part number 016101 would be: cgtqmx6eval_mfg_1024_64_400_defconfig
    
    Respectively, the correct configuration file for part number 016212 (conga-UMX6/iDC-1G eMMC4) would be: cgtumx6_mfg_1024_64_528_defconfig
    Please contact the congatec technical support if you are unsure how to determine the correct configuration file.
