| * mtd: mtd_torturetest can cause stack overflowsAl Cooper2013-02-131-14/+11Star
| | | | | | | | | | | | | | | | | | | | mtd_torturetest uses the module parm "ebcnt" to control the size of a stack based array of int's. When "ebcnt" is large, Ex: 1000, it causes stack overflows on systems with small kernel stacks. The fix is to move the array from the stack to kmalloc memory.

This patch will check NAND flash's ecc minimum requirement in ONFI parameter. 1. if pmecc-cap, pmecc-sector-size is set in dts. then use it. Driver will print out a WARNING if the values are different from ONFI parameters. 2. if pmecc-cap, pmecc-sector-size is not set in dts, then use the value from ONFI parameters. * If ONFI ECC parameters are in ONFI extended parameter page, since we are not support it, so assume the minimum ecc requirement is 2 bits in 512 bytes. * For non-ONFI support nand flash, also assume the minimum ecc requirement is 2 bits in 512 bytes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GF13 can be only used in the following case: The ECC data chunk is less then 1K bytes. In mx23/mx28, the ecc data chunk is 512 bytes. So it is okay. But in mx6q, we begin to use some large nand chip whose ecc data chunk maybe 1K bytes long. So when the data chunk is 1K bytes, we have to use the GF14. This patch sets the Golois Field bit when the GF14 is needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The panic_nand_wait() expects the timeo in ms and not in jiffies. But in nand_wait(), the timeo for panic_nand_wait() is assigned with wrong value(jiffies + some delay). The timeo should be set like the panic_nand_write() does. This patch passes timeo in ms to panic_nand_wait(). And this patch also passes timeo in jiffies(converted by msecs_to_jiffies) to time_before() which makes the code more readable.

| * mtd: cfi_cmdset_0002: Support Persistent Protection Bits (PPB) lockingStefan Roese2013-02-042-0/+218
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently cfi_cmdset_0002.c does not support PPB locking of sectors. This patch adds support for this locking/unlocking mechanism. It is needed on some platforms, since newer U-Boot versions do support this PPB locking and protect for example their environment sector(s) this way. This PPB locking/unlocking will be enabled for all devices supported by cfi_cmdset_0002 reporting 8 in the CFI word 0x49 (Sector Protect/Unprotect scheme). Please note that PPB locking does support sector-by-sector locking. But the whole chip can only be unlocked together. So unlocking one sector will automatically unlock all sectors of this device. Because of this chip limitation, the PPB unlocking function saves the current locking status of all sectors before unlocking the whole device. After unlocking the saved locking status is re-configured. This way only the addressed sectors will be unlocked. To selectively enable this advanced sector protection mechanism, the device-tree property "use-advanced-sector-protection" has been created. To enable support for this locking this property needs to be present in the flash DT node. E.g.: nor_flash@0,0 { compatible = "amd,s29gl256n", "cfi-flash"; bank-width = <2>; use-advanced-sector-protection; ... Tested with Spansion S29GL512S10THI and Micron JS28F512M29EWx flash devices.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ELM module can be used for hardware error correction of BCH 4 & 8 bit. ELM module functionality is verified by checking the availability of handle for ELM module in device tree. Hence supporting 1. ELM module available, BCH error correction done by ELM module. Also support read & write page in one shot by adding custom read_page and write_page methods. This helps in optimizing code for NAND flashes with page size less than 4 KB. 2. If ELM module not available fall back to software BCH error correction support. New structure member is added to omap_nand_info 1. "is_elm_used" to know the status of whether the ELM module is used for error correction or not. 2. "elm_dev" device pointer to elm device on detection of ELM module. Also being here update the device tree documentation of gpmc-nand for adding optional property elm_id. Note: ECC layout uses 1 extra bytes for 512 byte of data to handle erased pages. Extra byte programmed to zero for programmed pages. Also BCH8 requires 14 byte ecc to maintain compatibility with RBL ECC layout. This results a common ecc layout across RBL, U-boot & Linux with BCH8. Signed-off-by: Philip Avinash <avinashphilip@ti.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

| * mtd: davinci_nand: fix modular build with CONFIG_OF=ySergei Shtylyov2013-02-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit cdeadd712f52b16a9285386d61ee26fd14eb4085 (mtd: nand: davinci: add OF support for davinci nand controller) has never been really build tested with the driver as a module. When the driver is built-in, the missing semicolon after structure initializer is "compensated" by MODULE_DEVICE_TABLE() macro being empty and so the initializer using the trailing semicolon on the next line; when the driver is built as a module, compilation error ensues, and as the 'davinci_all_defconfig' has the NAND driver modular, this error prevents DaVinci family kernel from building...

The biggy in there is a whitespace cleanup. After I was sent another set of whitespace cleanup patches I decided it was the time to clean the whitespace "issues" for once and and that touches many files below arch/mips/. Fix up silly conflicts, mostly due to whitespace cleanups. * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (105 commits) MIPS: Quit exporting kernel internel break codes to uapi/asm/break.h MIPS: remove broken conditional inside vpe loader code MIPS: SMTC: fix implicit declaration of set_vi_handler MIPS: early_printk: drop __init annotations MIPS: Probe for and report hardware virtualization support.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The nvram functions are exported and used by some normal drivers. To prevent name clashes with ofter parts of the kernel code add a bcm47xx_ prefix in front of the function names and the header file name.
