| * | Add configurability via devicetreeSascha Hauer2013-07-184-0/+264
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the possibility to configure the place for the environment from the devicetree and to partition devices from the devicetree. Configuration has the general form of devices with a regular compatible property. This allows to later add additional drivers or drivers with different behaviour (for example to add support for redundant environment). The configuration is all in the /chosen/barebox/ hierarchy of the devicetree. This separates the configuration from the hardware description. Also it makes it possible to store the configuration in a completely separate devicetree (or devicetree overlay). For the same reason all configuration is done using nodepathes rather than phandles.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MXS specific devices have some common infrastructure in the kernel known as STMP devices. We have the same in barebox, but with a mxs_ prefix instead of a stmp_ prefix. As some STMP devices are also found on i.MX6 move the common infrastructure out of MXS specific files and use the stmp_ prefix. This is done in preparation for i.MX6 NAND support.

It is synchronized as best as we can get: - locks removed - The splitting in different files we had to better support different features has been dropped. Instead this is now done mostly with the use of __maybe_unused Some barebox adjustments are forward ported, like: - Allow partial page writes - Optionally allow to erase bad blocks - check for all_ff before writing a page Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

Then, as new bad blocks are marked over time, the OOB markers become incomplete and the flash-based table becomes the only source of current bad block information. This becomes an obvious problem when, for example: * code accessing the flash cannot read the flash-based BBT format * BBT is corrupted and the flash must be rescanned for bad blocks; we want to remember bad blocks that were marked from Linux So to keep the bad block markers in sync with the flash-based BBT, this patch changes the default so that we write bad block markers to the proper OOB area on each block in addition to flash-based BBT. Comments are updated, expanded, and/or relocated as necessary. The new flash-based BBT procedure for marking bad blocks: (1) erase the affected block, to allow OOB marker to be written cleanly (2) update in-memory BBT (3) write bad block marker to OOB area of affected block (4) update flash-based BBT Note that we retain the first error encountered in (3) or (4), finish the procedures, and dump the error in the end. This should handle power cuts gracefully enough. (1) and (2) are mostly harmless (note that (1) will not erase an already-recognized bad block). The OOB and BBT may be "out of sync" if we experience power loss bewteen (3) and (4), but we can reasonably expect that on next boot, subsequent I/O operations will discover that the block should be marked bad again, thus re-syncing the OOB and BBT. Note that this is a change from the previous default flash-based BBT behavior. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
