ppc4xx: Fix ECC Correction bug with SMC ordering for NDFC driver

2009-08-25T15:41:42+00:00

Fix ECC Correction bug where the byte offset location were double
flipped causing correction routine to toggle the wrong byte location
in the ECC segment. The ndfc_calculate_ecc routine change the order
of getting the ECC code.
        /* The NDFC uses Smart Media (SMC) bytes order */
        ecc_code[0] = p[2];
        ecc_code[1] = p[1];
        ecc_code[2] = p[3];
But in the Correction algorithm when calculating the byte offset
location, the s1 is used as the upper part of the address. Which
again reverse the order making the final byte offset address
location incorrect.
	byteoffs = (s1 << 0) & 0x80;
	.
	.
	byteoffs |= (s0 >> 4) & 0x08;
The order is change to read it in straight and let the correction
function to revert it to SMC order.

flash: Fix CFI buffer size bug

2009-08-13T07:28:20+00:00

Fix bug introduced by 9c048b523413ae5f3ff34e00cf57569c3368ab51.

The cfi_flash.c driver cast the flash buffer size to a uchar in
flash_write_cfibuffer(). On some flash parts, (tested on Numonyx
part PC32F512M29EWH), the buffer size is 1KB. Remove the cast to
uchar to enable buffer sizes to be larger.

Add driver for the ST M95xxx SPI EEPROM

2009-08-09T21:45:14+00:00

This chip is used in a number of boards manufactured by Calao-Systems
which should be supported soon. This driver provides the necessary
spi_read and spi_write functions necessary to communicate with the chip.

Remove legacy NAND and disk on chip code.

2009-07-17T00:07:47+00:00

Legacy NAND had been scheduled for removal.  Any boards that use this
were already not building in the previous release due to an #error.

The disk on chip code in common/cmd_doc.c relies on legacy NAND,
and it has also been removed.  There is newer disk on chip code
in drivers/mtd/nand; someone with access to hardware and sufficient
time and motivation can try to get that working, but for now disk
on chip is not supported.

nand: ndfc: Remove unnecessary #ifdef's

2009-07-16T22:52:03+00:00

Now that the 4xx NAND driver ndfc is moved to the common NAND driver
directory we don't need this #ifdef's anymore.
