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

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