This patch works with the following three flags from two headers (nand.h and bbm.h): (1) NAND_USE_FLASH_BBT (nand.h) (2) NAND_USE_FLASH_BBT_NO_OOB (nand.h) (3) NAND_BBT_NO_OOB (bbm.h) These flags are all related and interdependent, yet they were in different headers. Flag (2) is simply the combination of (1) and (3) and can be eliminated. This patch accomplishes the following: * eliminate NAND_USE_FLASH_BBT_NO_OOB (i.e., flag (2)) * move NAND_USE_FLASH_BBT (i.e., flag (1)) to bbm.h It's important to note that because (1) and (3) are now both found in bbm.h, they should NOT be used in the "nand_chip.options" field. I removed a small section from the mtdnand DocBook because it referes to NAND_USE_FLASH_BBT in nand.h, which has been moved to bbm.h.

*
|
|
* Modified from original 644X-EVM board support.
|

|
|
* The Neuros OSD 2.0 is the hardware component of the Neuros Open
|
|
* Internet Television Platform. Hardware is very close to TI
|
|
* DM644X-EVM board. It has:
|
|
* DM6446M02 module with 256MB NAND, 256MB RAM, TLV320AIC32 AIC,
|
|
* USB, Ethernet, SD/MMC, UART, THS8200, TVP7000 for video.
|
|
* Additionally realtime clock, IR remote control receiver,
|
|
* IR Blaster based on MSP430 (firmware although is different
|
|
* from used in DM644X-EVM), internal ATA-6 3.5” HDD drive
|
|
* with PATA interface, two muxed red-green leds.
|
|
*
