> 
> This patch allow to override CONFIG_SYS_TCLK from board configuration
> files. This is needed for the Network Space v2 which use a non standard
> core clock frequency (166MHz instead of 200MHz for a 6281 SoC).
> 
> As a possible enhancement for 6281 and 6282 devices, TCLK could be
> dynamically detected by checking the Sample at Reset register bit 21.
> 
> Additionally this patch fix a typo.
