mtd: mtdram: Expose module parameters Since we can set module parameters also when a driver is built in, it makes no sense to protect module parameter with #ifdef MODULE.

mtd: Stop updating erase_info->state and calling mtd_erase_callback() 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.

mtd: mtdram: properly handle the phys argument in the point method When the phys pointer is non null, the point method is expected to return the physical address for the pointed area. In the case of the mtdram driver we have to retrieve the physical address for the corresponding vmalloc area. However, there is no guarantee that the vmalloc area is made of physically contiguous pages. In that case we simply limit retlen to the actually contiguous pages.

mtd: harmonize mtd_point interface implementation Some MTD drivers return -EINVAL if the 'phys' parameter is not NULL, trying to convey that they cannot return the physical address. However, this is not very logical because they still can return the virtual address ('virt'). But some drivers (lpddr) just ignore the 'phys' parameter instead, which is a more logical thing to do. Let's harmonize this and: 1. Always initialize 'virt' and 'phys' to 'NULL' in 'mtd_point()'. 2. Do not return an error if the physical address cannot be found. So as a result, all drivers will set 'phys' to 'NULL' if it is not supported. None of the 'mtd_point()' users use 'phys' anyway, so this should not break anything. I guess we could also just delete this parameter later. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

mtd: do not duplicate length and offset checks in drivers We already verify that offset and length are within the MTD device size in the MTD API functions. Let's remove the duplicated checks in drivers. This patch only affects the following API's: 'mtd_erase()' 'mtd_point()' 'mtd_unpoint()' 'mtd_get_unmapped_area()' 'mtd_read()' 'mtd_write()' 'mtd_panic_write()' 'mtd_lock()' 'mtd_unlock()' 'mtd_is_locked()' 'mtd_block_isbad()' 'mtd_block_markbad()' This patch adds a bit of noise by removing too sparse empty lines, but this is not too bad.

mtd: return error code from mtd_unpoint The 'mtd_unpoint()' API function should be able to return an error code because it may fail if you specify incorrect offset. This patch changes this MTD API function and amends all the drivers correspondingly. Also return '-EOPNOTSUPP' from 'mtd_unpoint()' when the '->unpoint()' method is undefined. We do not really need this currently, but this just makes sense to be consistent with 'mtd_point()'.

mtd: add leading underscore to all mtd functions 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.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
