* Remove NAND and NANDFS supportWarner Losh2019-06-251-24/+0
| | | | | | | | | | | | | | | | | | | | | NANDFS has been broken for years. Remove it. The NAND drivers that remain are for ancient parts that are no longer relevant. They are polled, have terrible performance and just for ancient arm hardware. NAND parts have evolved significantly from this early work and little to none of it would be relevant should someone need to update to support raw nand. This code has been off by default for years and has violated the vnode protocol leading to panics since it was committed. Numerous posts to arch@ and other locations have found no actual users for this software.

* Support device-independent labels for geom_flashmap slices.Ian Lepore2019-03-241-9/+12
| | | | | | | | | | | | | | | | | While geom_flashmap has always supported label names for its slices, it does so by appending "s.labelname" to the provider device name, meaning you still have to know the name and unit of the hardware device to use the labels. These changes add support for device-independent geom_flashmap labels, using the standard geom_label infrastructure. geom_flashmap now creates a softc struct attached to its geom, and as it creates slices it stores the label into an array in the softc. The new geom_label_flashmap uses those labels when tasting a geom_flashmap provider. Differential Revision: https://reviews.freebsd.org/D19535 Notes: svn path=/head/; revision=345480
* sys/geom: adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326270

The FDT slicer still is the default for CFI, NAND and SPI flash on FDT-enabled platforms. - In addition to a device_t, also pass the name of the GEOM provider in question to the slicers as a single device may provide more than provider. - Build a geom_flashmap.ko. - Use MODULE_VERSION() so other modules can depend on geom_flashmap(4). - Remove redundant/superfluous GEOM routines that either do nothing or provide/just call default GEOM (slice) functionality. - Trim/adjust includes Submitted by: jhibbits (RouterBoard bits) Reviewed by: jhibbits Notes: svn path=/head/; revision=314097

* Create a RouterBoard platform and use it to create a flash mapJustin Hibbits2015-08-221-1/+10
| | | | | | | | | | | | | | | | Summary: The RouterBoard uses a predefined partition map which doesn't exist in the fdt. This change allows overriding the fdt slicer with a custom slicer, and uses this custom slicer to define the flash map on the RouterBoard RB800. D3305 converts the mpc85xx platform into a base class, so that systems based on the mpc85xx platform can add their own overrides. This change builds on D3305, and creates a RouterBoard (RB800) platform to initialize the slicer override.

* MFP4 @222836Brooks Davis2013-05-301-2/+5

* Partial MFP4 of 222836:Brooks Davis2013-04-161-1/+1
| | | | | | | | | | | | | | Only look for FDT partitions if our potential parent is a DISK device. Excluding direct recursion on the flashmap geoms was insufficient because it did not prevent the underlying device from being retrieved if flashmap geoms were further partitioned.
