2010-08-12nand/denali: change read_status function methodChuanxiao Dong
In mtd->write, Denali controller will use MODE_11 mode to read NAND flash status, then return back to MODE_1O mode to do page write. Here comes a bug for this kind of using, sometimes controller will not write data to NAND and just return a good interrupt to tell driver writing work is done. The data in this page is all 0xff and this page can not be written again. The reason is unknow. So read Denali controller register WRITE_PROTECT to get NAND status instead.

2010-08-05mtd: denali: update get nand para functionsChuanxiao Dong
In denali driver, wTotalBlocks variable is useless, so just remove them in get_toshiba_nand_para and get_hynix_nand_para first. Other wTotalBlocks in denali.c and other variables in dev_info struct are also useless, will remove them later. Also add a parameter in get_hynix_nand_para to prepare to remove dev_info struct. This parameter comes by reading NAND ID directly. Reading register will report wrong value for some NAND chips, e.g. some Micron MT29F32G08QAA chips. So update NAND_CMD_READID method as well.

2010-08-05mtd: Blackfin NFC: fix nand busy detectionBarry Song
The IRQSTAT register is a W1C register used by the interrupt handler and may have its BUSY bit changed. This makes it somewhat unreliable for the polling devready function. So switch it over to use the BUSY bit in the STAT register that always reflects the current state of the hardware. This fixes driver hangs seen when the NAND flash is under heavy system load (like I/O benchmarks).

2010-08-05mtd: Blackfin NFC: fix handling of page sizesBarry Song
Rather than forcing the platform resources to declare the desired page size, simply use the existing information passed down to us by the higher layers.

2010-08-05mtd: Blackfin NFC: wait for the ECC reset to finishBarry Song
When resetting the ECC registers/counters, the bit will automatically clear itself once the reset has actually finished.

2010-08-05mtd: Blackfin NFC: fix raw page write/read handlingBarry Song
Our write_buf/read_buf funcs always do ECC in HW ECC mode. That is not needed for raw funcs. In fact, write_buf/read_buf should be a pure func for data input/output while chip->ecc.hwctl controls ECC. Unfortunately, we can't separate ECC from normal data input/output in our NFC, so our DMA write_buf/read_buf entries are coupled with ECC operations closely. Thus we need to provide dedicated read_page_raw/write_page_raw funcs where we do non-DMA transactions so as to avoid automatic ECC.
