   1 Board information
   2 -----------------
   3
   4 The SBC produced by Phytec has a SOM based on a i.MX6Q.
   5 The SOM is sold in two versions, with eMMC or with NAND. Support
   6 here is for the SOM with NAND.
   7 The evaluation board "phyBoard-Mira" is thought to be used
   8 together with the SOM.

  10 More information on the board can be found on manufacturer's

  16 Building U-Boot
  17 -------------------------------
  18
  19 $ make pcm058_defconfig
  20 $ make
  21
  22 This generates the artifacts SPL and u-boot.img.
  23 The SOM can boot from NAND or from SD-Card, having the SPI-NOR
  24 as second option.
  25 The dip switch "DIP-1" on the board let choose between
  26 NAND and SD.
  27
  28 DIP-1 set to off:       Boot first from NAND, then try SPI
  29 DIP-1 set to on:        Boot first from SD, then try SPI
  30
  31 The bootloader was tested with DIP-1 set to on. If a SD-card
  32 is present, then the RBL tries to load SPL from the SD Card, if not,
  33 RBL loads from SPI-NOR. The SPL tries then to load from the same
  34 device where SPL was loaded (SD or SPI). Booting from NAND is
  35 not supported.
