Linux Network Port Drive implementation (to be continued)

The drive is located under Linux/driver/net.

1. Register read/write

Asm/io.h

#define __RAW_WRITEB (V,a) (__chk_io_ptr (a), * (volatile unsigned char __force *) (a) = (v))
#define __RAW_READB (a) (__chk_io_ptr (a), * (volatile unsigned char __force *) (a))

DB->IO_ADDR = Ioremap (Db->addr_res->start, iosize);
Db->io_data = Ioremap (Db->data_res->start, iosize);

Static U8
IOR (board_info_t * db, int reg)
{
Writeb (Reg, DB->IO_ADDR);
Return readb (Db->io_data);
}

static void
IOW (board_info_t * db, int reg, int value)
{
Writeb (Reg, DB->IO_ADDR);
Writeb (value, db->io_data);
}
