Greetings,

Please, could anyone tell me, what is the value expected in
set_io_map and set_mem_map. Is it the cycle time (normally, 255ns for io)?

This question appeared because of following defines in soc_common.h,
where times are definitely not cycle times.

#define SOC_PCMCIA_IO_ACCESS		(165)
#define SOC_PCMCIA_5V_MEM_ACCESS	(150)
#define SOC_PCMCIA_3V_MEM_ACCESS	(300)
#define SOC_PCMCIA_ATTR_MEM_ACCESS	(300)
