[U-Boot] [PATCH] armv8/ls1043a: Add MTD partition scheme

[Wenbin Song]

Hi: York

1, There is an issue for sdk2.0 kernel that the nor-flash can't be probed . we can fix it as follow:

$make menuconfig

  x     -> Device Drivers                                                                                                                                                                       
  x        -> Memory Technology Device (MTD) support 
  x          -> RAM/ROM/Flash chip drivers                                                                                                                
  x            -> Flash chip driver advanced configuration options 
  x                -> Flash cmd/query data swapping                                                                                         
       x x                  ( ) NO                                   
       x x                  (X) BIG_ENDIAN_BYTE                     
       x x                  ( ) LITTLE_ENDIAN_BYTE                   

Enable BIG_ENDIAN_BYTE .

2,  The  spi-nor flash can working on  ls1043aqds , and I use the sdk2.0 kernel (ce5a3841f3).
      [    1.598954] m25p80 spi0.0: n25q128a11 (16384 Kbytes)
