2019-01-17sfc: extend MTD support for newer hardwareBert Kenward1-0/+3
The X2 family of NICs (based on the SFC9250) have additional MTD partitions for firmware and configuration. This includes partitions that are read-only. The NICs also have extended versions of the NVRAM interface, allowing more detailed status information to be returned. Signed-off-by: Bert Kenward <bkenward@solarflare.com> Signed-off-by: David S.

2018-03-21mtd: Stop updating erase_info->state and calling mtd_erase_callback()Boris Brezillon1-10/+1
MTD users are no longer checking erase_info->state to determine if the erase operation failed or succeeded. Moreover, mtd_erase_callback() is now a NOP. We can safely get rid of all mtd_erase_callback() calls and all erase_info->state assignments. While at it, get rid of the erase_info->state field, all MTD_ERASE_XXX definitions and the mtd_erase_callback() function.

2013-08-27sfc: Move MTD operations into efx_nic_typeBen Hutchings1-556/+8
Merge the per-NIC-type MTD probe selection and struct efx_mtd_ops into struct efx_nic_type. Move the implementations into the appropriate source files. Several NVRAM functions are now only called from MTD operations which are now implemented in the same file (falcon.c or mcdi.c). There is no need for them to be extern, or to be defined at all if CONFIG_SFC_MTD is not enabled, so move them into the #ifdef CONFIG_SFC_MTD sections in those files. Most of the SPI-related definitions are also only used in falcon.c, so move them there. Put the remainder of spi.h into nic.h (which previously included it).

2013-08-22sfc: Eliminate struct efx_mtdBen Hutchings1-160/+119
Currently we use struct efx_mtd to represent a physical NVRAM device and struct efx_mtd_partition to represent a partition on that device. But this only really makes sense for Falcon, as we don't know or care whether MC-managed NVRAM partitions are on one or more physical devices. It complicates iteration and provides little benefit. Therefore: - Replace the pointer to efx_mtd in mtd_info::priv with a pointer to efx_nic - Move the falcon_spi_device pointer into the union in struct efx_mtd_partition - Move the device name to efx_mtd_partition::dev_type_name - Move the efx_mtd_ops pointer to efx_nic::mtd_ops - Make efx_nic::mtd_list a list of partitions Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

2012-03-30Merge tag 'for-linus-3.4' of git://git.infradead.org/mtd-2.6Linus Torvalds1-5/+5
Pull MTD changes from David Woodhouse: - Artem's cleanup of the MTD API continues apace. - Fixes and improvements for ST FSMC and SuperH FLCTL NAND, amongst others. - More work on DiskOnChip G3, new driver for DiskOnChip G4. - Clean up debug/warning printks in JFFS2 to use pr_<level>. Fix up various trivial conflicts, largely due to changes in calling conventions for things like dmaengine_prep_slave_sg() (new inline wrapper to hide new parameter, clashing with rewrite of previously last parameter that used to be an 'append' flag, and is now a bitmap of 'unsigned long flags').

2012-03-27sfc: mtd: Use MTD_FAIL_ADDR_UNKNOWN instead of 0xffffffffShmulik Ladkani1-1/+1
As of bb0eb217, MTD_FAIL_ADDR_UNKNOWN should be used to indicate mtd erase failure not specific to any particular block. Use MTD_FAIL_ADDR_UNKNOWN instead of 0xffffffff when setting 'erase->fail_addr' in 'efx_mtd_erase()'.

2012-03-27mtd: add leading underscore to all mtd functionsArtem Bityutskiy1-4/+4
This patch renames all MTD functions by adding a "_" prefix: mtd->erase -> mtd->_erase mtd->read_oob -> mtd->_read_oob ... The reason is that we are re-working the MTD API and from now on it is an error to use MTD function pointers directly - we have a corresponding API call for every pointer. By adding a leading "_" we achieve the following: 1. Make sure we convert every direct pointer users 2. A leading "_" suggests that this interface is internal and it becomes less likely that people will use them directly 3. Make sure all the out-of-tree modules stop compiling and the owners spot the big API change and amend them.

2012-01-27sfc: Consistently test DEBUG macro, not EFX_ENABLE_DEBUGBen Hutchings1-0/+1
The netif_dbg() macro is defined in <linux/netdevice.h>. If the DEBUG macro is defined, it logs a message at 'debug' level, otherwise it does nothing. In net_driver.h we define DEBUG if EFX_ENABLE_DEBUG is defined, but this is too late for those source files that already got a definition of netif_dbg() by including <linux/netdevice.h> Get rid of EFX_ENABLE_DEBUG, and only define and test DEBUG. In mtd.c, we do not use DEBUG as a condition flag but are forced to use the DEBUG macro-function from <linux/mtd/mtd.h>. Undefine DEBUG before including it.
