Port linux2.6.18 to ARM9.

If you don't talk nonsense, let's talk about how to change it,

};

/* Map the Ethernet controller cs8900a */
{0xe0000000, _ phys_to_pfn (maid + 0x01000000), sz_1m, mt_device}
};
Static struct resource cs89x0_resources [] = {Drivers/NET/cs89x0. c
[0] = {

. End = 0x19000000 + 16,
. Flags = ioresource_mem,
},
[1] = {
. Start = irq_eint9,
. End = irq_eint9,
. Flags = ioresource_irq,
},
};
 
Static struct platform_device cs89x0_device = {
. Name = "cirrus-cs89x0 ",
. Num_resources = array_size (cs89x0_resources ),
. Resource = cs89x0_resources,
};

(3) add support for CS8900 Nic

(4) There are also added support for devfs. I will not say much about this because there are a lot of online materials.
(5) We recommend that you use the 3.4.1 compiler for compiling.
(6) There is a lot of information on the Internet to say that MTD should be removed from the ECC test on NAND, but after my tests, there will be many problems in doing so. In particular, when using the yaffs file system, you should turn off the ECC that comes with yaffs and use the mtd ecc.
(7) porting yaffs will be discussed later.
