* mtd: physmap_of: Add multiple regions and concatenation supportStefan Roese2009-06-061-56/+143
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support to handle multiple non-identical chips in one flash device tree node. It also adds concat support to physmap_of. This makes it possible to support e.g. the Intel P30 48F4400 chips which internally consists of 2 non-identical NOR chips on one die. Additionally partitions now can span over multiple chips. To describe such a chip's, multiple "reg" tuples are now supported in one flash device tree node. Here an dts example: flash@f0000000,0 { #address-cells = <1>; #size-cells = <1>; compatible = "cfi-flash"; reg = <0 0x00000000 0x02000000 0 0x02000000 0x02000000>; bank-width = <2>; partition@0 { label = "test-part1"; reg = <0 0x04000000>; }; }; Signed-off-by: Stefan Roese <sr@denx.de> Reviewed-by: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

| * [POWERPC] Cleanups for physmap_of.c (v2)David Gibson2007-09-201-125/+99Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch includes a whole batch of smallish cleanups for drivers/mtd/physmap_of.c. - A bunch of uneeded #includes are removed - We switch to the modern linux/of.h etc. in place of asm/prom.h - Use some helper macros to avoid some ugly inline #ifdefs - A few lines of unreachable code are removed - A number of indentation / line-wrapping fixes - More consistent use of kernel idioms such as if (!p) instead of if (p == NULL) - Clarify some printk()s and other informative strings. - parse_obsolete_partitions() now returns 0 if no partition information is found, instead of returning -ENOENT which the caller had to handle specially. - (the big one) Despite the name, this driver really has nothing to do with drivers/mtd/physmap.c. The fact that the flash chips must be physically direct mapped is a constrant, but doesn't really say anything about the actual purpose of this driver, which is to instantiate MTD devices based on information from the device tree. Therefore the physmap name is replaced everywhere within the file with "of_flash". The file itself and the Kconfig option is not renamed for now (so that the diff is actually a diff). That can come later. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
| * [POWERPC] Make partitions optional in physmap_ofJosh Boyer2007-09-201-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The latest physmap_of driver has a small error where it will fail the probe with: physmap-flash: probe of fff00000.small-flas failed with error -2 if there are no partition subnodes in the device tree and the old style binding is not used. Since partition definitions are optional, the probe should still succeed. Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com> Acked-by: David Gibson <david@gibson.dropbear.id.au>
| * [POWERPC] Document and implement an improved flash device binding for powerpcDavid Gibson2007-09-131-65/+174
| | | | | | | | | | | | | | | | | | | | | | | | This replaces the binding for flash chips in booting-without-of.txt with an clarified and improved version. It also makes drivers/mtd/maps/physmap_of.c recognize this new binding. Finally it revises the Ebony device tree source to use the new binding as an example.

* [MTD] of_device-based physmap driverVitaly Wool2006-12-081-0/+255
inlined below is the patch that adds physmap driver for of_device. It's an MTD part of the two-part support for flash/ROM devices based on Open Firmware descriptions. The arch part (currently only PowerPC which is no surprise) was introduced to powerpc folks earlier and recently the older version of the powerpc part has been included into the powerpc.git tree (see http://www.kernel.org/git/?p=linux/kernel/git/paulus/powerpc.git;a=commitdiff;h=28f9ec349ae47c91768b7bc5607db4442c818e11). drivers/mtd/maps/Kconfig | 9 + drivers/mtd/maps/Makefile | 1 drivers/mtd/maps/physmap_of.c | 255 ++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 265 insertions(+) Signed-off-by: Vitaly Wool <vwool@ru.mvista.com> Signed-off-by: Sergey Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
