On the enbw_cmc board is a KSZ8864RMN switch which needs
 | 
						|
configured through spi before working. This is done on
 | 
						|
startup from u-boot through a config file stored at an
 | 
						|
address specified in the "hwconfig" environment variable,
 | 
						|
subcommand "config".
 | 
						|
 | 
						|
For example on the enbw_cmc board:
 | 
						|
 | 
						|
hwconfig=switch:lan=on,pwl=off,config=0x60160000
 | 
						|
 | 
						|
The file has the following structure:
 | 
						|
 | 
						|
- a comment starts with a '#' or a ';' and ends with a newline
 | 
						|
- The switch needs for its config a reg/value pair, so we
 | 
						|
  have two columns in the file:
 | 
						|
    reg  : contains the register address
 | 
						|
    value: contains a 8 bit register value
 | 
						|
  This 2 columns are seperated through space or tab.
 | 
						|
 | 
						|
example (minimal configuration on the enbw_cmc board):
 | 
						|
 | 
						|
;reg    value   comment
 | 
						|
;-----------------------------------------
 | 
						|
0x01	0x00
 | 
						|
0x01	0x01    ; Start Switch with this configuration
