2012-02-07ENGR00173731-3 mxs-dma : rewrite the last parameter of mxs_dma_prep_slave_sg()Huang Shijie
[1] Background : The GPMI does ECC read page operation with a DMA chain consist of three DMA Command Structures. The middle one of the chain is used to enable the BCH, and read out the NAND page. The WAIT4END(wait for command end) is a comunication signal between the GPMI and MXS-DMA. [2] The current DMA code sets the WAIT4END bit at the last one, such as: +-----+ +-----+ +-----+ | cmd | ------------> | cmd | ------------------> | cmd | +-----+ +-----+ +-----+ ^ | | set WAIT4END here This chain works fine in the mx23/mx28. [3] But in the new GPMI version (used in MX50/MX60), the WAIT4END bit should be set not only at the last DMA Command Structure, but also at the middle one, such as: +-----+ +-----+ +-----+ | cmd | ------------> | cmd | ------------------> | cmd | +-----+ +-----+ +-----+ ^ ^ | | | | set WAIT4END here too set WAIT4END here If we do not set WAIT4END, the BCH maybe stalls in "ECC reading page" state. In the next ECC write page operation, a DMA-timeout occurs. This has been catched in the MX6Q board. [4] In order to fix the bug, rewrite the last parameter of mxs_dma_prep_slave_sg(), and use the dma_ctrl_flags: --------------------------------------------------------- DMA_PREP_INTERRUPT : append a new DMA Command Structrue. DMA_CTRL_ACK : set the WAIT4END bit for this DMA Command Structure. --------------------------------------------------------- [5] changes to the relative drivers: For gpmi-nand driver: use the new flags.

2012-01-31net: remove mm.h inclusion from netdevice.hAlexey Dobriyan
Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually). To prevent mm.h inclusion via other channels also extract "enum dma_data_direction" definition into separate header. This tiny piece is what gluing netdevice.h with mm.h via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h". Removal of mm.h from scatterlist.h was tried and was found not feasible on most archs, so the link was cutoff earlier. Hope people are OK with tiny include file. Note, that mm_types.h is still dragged in, but it is a separate story. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-01-19ENGR00169906-5 GPMI : change the code for new interfaceHuang Shijie
If we do not set the WAIT4END in the middle DMA command structure of the long DMA command chain, a DMA timeout may occurs. The reason of the DMA timeout is: [1] We do not set the WAIT4END in the DMA command structure which do the ECC READ PAGE by the BCH. [2] So the following DMA command structure (maybe in other DMA CHAIN)may disable the BCH module. [3] If the time delay between [2] and [1] is long enough, it's ok. But if the time delay is not long enough, the BCH module may become unnormal, so it can not finish its job. The DMA will timeout in this case. We have changed the DMA interface to fix the bug, now use the new interface. Acked-by: Jason Liu <r64343@freescale.com> Signed-off-by: Huang Shijie <b32955@freescale.com>

2011-11-11mtd: nand_base: always initialise oob_poi before writing OOB dataTHOMSON, Adam (Adam)
commit f722013ee9fd24623df31dec9a91a6d02c3e2f2f upstream. In nand_do_write_ops() code it is possible for a caller to provide ops.oobbuf populated and ops.mode == MTD_OOB_AUTO, which currently means that the chip->oob_poi buffer isn't initialised to all 0xFF. The nand_fill_oob() method then carries out the task of copying the provided OOB data to oob_poi, but with MTD_OOB_AUTO it skips areas marked as unavailable by the layout struct, including the bad block marker bytes. An example of this causing issues is when the last OOB data read was from the start of a bad block where the markers are not 0xFF, and the caller wishes to write new OOB data at the beginning of another block. In this scenario the caller would provide OOB data, but nand_fill_oob() would skip the bad block marker bytes in oob_poi before copying the OOB data provided by the caller. This means that when the OOB data is written back to NAND, the block is inadvertently marked as bad without the caller knowing. This has been witnessed when using YAFFS2 where tags are stored in the OOB. To avoid this oob_poi is always initialised to 0xFF to make sure no left over data is inadvertently written back to the OOB area.

commit 543e32d5ff165d0d68deedb0e3557478c7c36a4a upstream. This bug was introduced in f8155a40 ("mtd: pxa3xx_nand: rework irq logic") and causes the PXA3xx NAND controller fail to operate with NAND flash that has empty pages. According to the comment in this block, the hardware controller will report a double-bit error for empty pages, which can and must be ignored.

2011-11-11mtd: provide an alias for the redboot module nameAndres Salomon
commit d5de1907d0af22e1a02de2b16a624148517a39c2 upstream. parse_mtd_partitions takes a list of partition types; if the driver isn't loaded, it attempts to load it, and then it grabs the partition parser. For redboot, the module name is "redboot.ko", while the parser name is "RedBoot". Since modprobe is case-sensitive, attempting to modprobe "RedBoot" will never work. I suspect the embedded systems that make use of redboot just always manually loaded redboot prior to loading their specific nand chip drivers (or statically compiled it in).
