2012-09-29mtd: physmap_of: Add "no-unaligned-direct-access" DT propertyStefan Roese1-0/+14
On some platforms (e.g. MPC5200) a direct 1:1 mapping may cause problems with JFFS2 usage, as the local bus (LPB) doesn't support unaligned accesses as implemented in the JFFS2 code via memcpy(). By defining "no-unaligned-direct-access", the flash will not be exposed directly to the MTD users (e.g. JFFS2) any more.

2012-09-29mtd: allow uclinux map driver to be used on any ColdFire CPU platformGreg Ungerer1-1/+1
The uclinux.c map driver has traditionally been used only on non-MMU based systems. But there is no fundamental reason it can't be used on systems running with virtual memory. Some ColdFire CPU based systems now have full paged MMU hardware and can use the uclinux.c mapping driver, so making the uclinux.c driver configuration depend on !CONFIG_MMU doesn't make sense now. Allow the CONFIG_MTD_UCLINUX option to be enabled if CONFIG_COLDFIRE is enabled. (I have chosen not to just more generally allow uclinux.c for any MMU type to keep this option hidden for most systems that are not interested in setting it).

2012-09-29mtd: fix wrong usage of ioremap_nocache() in uclinux.c map driverGreg Ungerer1-6/+9
The uclinux.c mapping driver uses ioremap_nocache() to map its physical mapping address to a system virtual address. Problem is that the region it is mapping is not device memory. It is ordinary system RAM. On most non-MMU systems this doesn't matter, and the mapping is always a 1:1 translation of the address. On paged memory systems on some architectures the page table mappings are not compatible between normal RAM and device memory. If we want to use the uclinux.c mapping driver on real MMU enabled systems we should be using the kernel virtual address that the mapping is at. For architectures that support the traditional initrd they use phys_to_virt or __va to convert the physical start initrd address to a kernel usable virtual address. The uclinux filesystem mapping is even more restrictive than the typical initrd, it always follows the kernels own bss section (so always in directly mapped memory). Therefore we can use the usual phys_to_virt to translate the physical start address to a virtual address.

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system Pull "Disintegrate and delete asm/system.h" from David Howells: "Here are a bunch of patches to disintegrate asm/system.h into a set of separate bits to relieve the problem of circular inclusion dependencies. I've built all the working defconfigs from all the arches that I can and made sure that they don't break. The reason for these patches is that I recently encountered a circular dependency problem that came about when I produced some patches to optimise get_order() by rewriting it to use ilog2(). This uses bitops - and on the SH arch asm/bitops.h drags in asm-generic/get_order.h by a circuituous route involving asm/system.h. The main difficulty seems to be asm/system.h. It holds a number of low level bits with no/few dependencies that are commonly used (eg. memory barriers) and a number of bits with more dependencies that aren't used in many places (eg. switch_to()). These patches break asm/system.h up into the following core pieces: (1) asm/barrier.h Move memory barriers here. This already done for MIPS and Alpha. (2) asm/switch_to.h Move switch_to() and related stuff here. (3) asm/exec.h Move arch_align_stack() here. Other process execution related bits could perhaps go here from asm/processor.h. (4) asm/cmpxchg.h Move xchg() and cmpxchg() here as they're full word atomic ops and frequently used by atomic_xchg() and atomic_cmpxchg(). (5) asm/bug.h Move die() and related bits. (6) asm/auxvec.h Move AT_VECTOR_SIZE_ARCH here. Other arch headers are created as needed on a per-arch basis." Fixed up some conflicts from other header file cleanups and moving code around that has happened in the meantime, so David's testing is somewhat weakened by that.

2012-03-27mtd: add leading underscore to all mtd functionsArtem Bityutskiy2-4/+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.

2012-01-09mtd: lantiq-flash: drop iounmap for devm_ allocated dataJulia Lawall1-5/+1
Data allocated with devm_ioremap or devm_ioremap_nocache should not be freed using iounmap, because doing so causes a dangling pointer, and a subsequent double free. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ expression x; @@ ( x = devm_ioremap(...) | x = devm_ioremap_nocache(...) ) @@ expression r.x; @@ * iounmap(x) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

Arch setup code might want to use their own partition parsers, but still use the generic physmap flash driver.

2012-01-09mtd: maps: bcm963xx-flash: make CFE partition parsing an mtd parserJonas Gorski2-150/+4
Recent BCM63XX devices support a variety of flash types (parallel, SPI, NAND) and share the partition layout. To prevent code duplication make the CFE partition parsing code a stand alone mtd parser to allow SPI or NAND flash drivers to use it.

Replace raw printk's with their pr_XXX equivalent and unify broken up strings so they become grepable. Also replace the PFX definition with a pr_fmt().

2012-01-09mtd: convert drivers/mtd/* to use module_platform_driver()Axel Lin11-129/+11
This patch converts the drivers in drivers/mtd/* to use the module_platform_driver() macro which makes the code smaller and a bit simpler.
