2013-09-14mtd: tegra-nor: Use staged read from NORManoj Chourasia
Most of the large read requests passed by upper MTD block layer are for highmem region which dma_map_single cannot handle. Those requests were getting serviced by memcpy_fromio, this was degrading performance. Moreover the memory region passed to dma_map_single should be on cache line boundaries. If the requirement is not met then system may crash due to cache incoherency. The approach added in this patch is to have a DMA coherent memory buffer. Read device via DMA to this coherent buffer and them memcpy it to user space pointer. This not only fixes some bugs but also enhances the NOR read performance. bug 928788 bug 898250 Signed-off-by: Manoj Chourasia <mchourasia@nvidia.com> Reviewed-on: http://git-master/r/76866 (cherry picked from commit 1491c0461a627c3bb63b01e126585eff9922ba1a) Change-Id: Ic8e24d2cc965f84bb97d2b6b29f27458aba17720 Reviewed-on: http://git-master/r/84026 Tested-by: Manoj Chourasia <mchourasia@nvidia.com> Reviewed-by: Varun Wadekar <vwadekar@nvidia.com> Rebase-Id: Ree1195ff059814e12710091201cae1df4ab661e9

2013-02-04mtd: cfi_cmdset_0002: Support Persistent Protection Bits (PPB) lockingStefan Roese
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.

This allows to put the filesystem at a defined address in ROM allowing to save more precious RAM. I think it's safe to default to ROM because the intention of using the uclinux map is to use a romfs and so mtd-ram doesn't give you anything that mtd-rom doesn't.

Convert all uses of devm_request_and_ioremap() to the newly introduced devm_ioremap_resource() which provides more consistent error handling. devm_ioremap_resource() provides its own error messages so all explicit error messages can be removed from the failure code paths.

Commit d68cbdd4fb (mtd: physmap_of: allow to specify the mtd name for retro compatiblity) broke cmdline partitioning using dev_name() in the kernel command line. of_property_read_string() does not touch mtd_name when linux,mtd-name is not present in the device tree, which causes map.name to be set to a random value. Fix this by initializing mtd_name to NULL.

2013-01-03Drivers: mtd: remove __dev* attributes.Greg Kroah-Hartman
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-12-10mtd: physmap_of: error checking to prevent a NULL pointer dereferenceAnton Prins
This patch solves a NULL pointer dereference, this may occur if the tuple is not mappable (jumps to continue in the for-loop). Out of the loop possible results are: - info->list_size == 0 if no of the tuples is mappable - info->list_size == 1 - info->list_size > 1 If no one of the supplied tuples is mappable (info->list_size == 0) and info->cmtd will not be set. But it is used in mtd_device_parse_register, OOPS! actually it should generate an error in this case!
