| * mtd: brcmnand: respect ECC algorithm set by NAND subsystemBrian Norris2016-05-051-1/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is more obvious than guessing based on ECC strength. It allows using NAND on devices with BCH-1 (e.g. D-Link DIR-885L). This maintains DT backward compatibility by defaulting to Hamming if a 1-bit ECC algorithm is specified without a corresponding algorithm selection. i.e., to use BCH-1, you must specify: nand-ecc-strength = <1>; nand-ecc-step-size = <512>; nand-ecc-algo = "bch"; Also adds a check to ensure we haven't allowed someone to get by with SW ECC. If we want to support SW ECC, we need to refactor some other pieces of this driver.

| * gpmi-nand: Handle ECC Errors in erased pagesMarkus Pargmann2016-05-051-5/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ECC is only calculated for written pages. As erased pages are not actively written the ECC is always invalid. For this purpose the Hardware BCH unit is able to check for erased pages and does not raise an ECC error in this case. This behaviour can be influenced using the BCH_MODE register which sets the number of allowed bitflips in an erased page. Unfortunately the unit is not capable of fixing the bitflips in memory. To avoid complete software checks for erased pages, we can simply check buffers with uncorrectable ECC errors because we know that any erased page with errors is uncorrectable by the BCH unit. This patch adds the generic nand_check_erased_ecc_chunk() to gpmi-nand to correct erased pages. To have the valid data in the buffer before using them, this patch moves the read_page_swap_end() call before the ECC status checking for-loop.

| | | | | | | | | | | | | | | | | | | | | | | | | | So far it was only possible to specify ECC algorithm using "soft" and "soft_bch" values of nand-ecc-mode prop. There wasn't a way to specify it for a hardware ECC mode. Now that we have independent field in NAND subsystem for storing info about ECC algorithm we may also add support for this new DT property.

| | | | | | | | | | | | | | | | | | | | | | There isn't any difference between handling NAND_ECC_SOFT and NAND_ECC_SOFT_BCH now. What matters is the new field called "algo". Please note we're keeping backward DT compatibility. We are still treating "soft_bch" value as the one setting Hamming algorithm, it's just handled in of_get_nand_ecc_algo now.

For a very short period of time we should support both values: NAND_ECC_SOFT and NAND_ECC_SOFT_BCH treating them the same. It's because of_get_nand_ecc_mode may still be setting NAND_ECC_SOFT_BCH.

| * mtd: nand: omap2: Start dma request before enabling prefetchCooper Jr., Franklin2016-05-051-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The prefetch engine sends a dma request once a FIFO threshold has been met. No other requests are received until the previous request is handled. Starting a dma transfer (dma_async_issue_pending) results in any previous event for the dma channel to be cleared. Therefore, starting the prefetch engine before initiating the dma transfer may result in the prefetch triggering a dma request but instead of it being handled it can end up being cleared. This will result in a hang since the code will continue to wait for the dma request to complete. By initiating the dma request before enabling the prefetch engine this race condition is avoided and no dma request are missed/cleared.

| * mtd: nandsim: add __init attributeJulia Lawall2016-05-051-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add __init attribute on functions that are only called from other __init functions and that are not inlined, at least with gcc version 4.8.4 on an x86 machine with allyesconfig. Currently, the functions are put in the .text.unlikely segment. Declaring them as __init will cause them to be put in the .init.text and to disappear after initialization. The result of objdump -x on the functions before the change is as follows: 000000000000059a l F .text.unlikely 0000000000000239 alloc_device 000000000000034e l F .text.unlikely 000000000000002e get_partition_name 00000000000007d3 l F .text.unlikely 00000000000005da init_nandsim And after the change it is as follows: 0000000000000029 l F .init.text 0000000000000234 alloc_device 0000000000000000 l F .init.text 0000000000000029 get_partition_name 000000000000025d l F .init.text 00000000000005d5 init_nandsim Done with the help of Coccinelle. The semantic patch checks for local static non-init functions that are called from an __init function and are not called from any other function.
