2017-11-27sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni
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=326255

2014-02-02Follow r261352 by updating all drivers which are children of simplebusIan Lepore
to check the status property in their probe routines. Simplebus used to only instantiate its children whose status="okay" but that was improper behavior, fixed in r261352. Now that it doesn't check anymore and probes all its children; the children all have to do the check because really only the children know how to properly interpret their status property strings. Right now all existing drivers only understand "okay" versus something- that's-not-okay, so they all use the new ofw_bus_status_okay() helper. Notes: svn path=/head/; revision=261410

Rework the timeout code to use actual time rather than a DELAY() loop and to use both typical and maximum to allow logging of timeout failures. Also correct the erase timeout, it is specified in milliseconds not microseconds like the other timeouts. Do not invoke DELAY() between status queries as this adds significant latency which in turn reduced write performance substantially. Sanity check timeout values from the hardware. Implement support for buffered writes (only enabled on Intel/Sharp parts for now). This yields an order of magnitude speedup on the 64MB Intel StrataFlash parts we use. When making a copy of the block to modify, also keep a clean copy around until we are ready to commit the block and use it to avoid unnecessary erases. In the non-buffer write case, also use it to avoid unnecessary writes when the block has not been erased. This yields a significant speedup when doing things like zeroing a block.

2010-07-11Convert Freescale PowerPC platforms to FDT convention.Rafal Jaworowski
The following systems are affected: - MPC8555CDS - MPC8572DS This overhaul covers the following major changes: - All integrated peripherals drivers for Freescale MPC85XX SoC, which are currently in the FreeBSD source tree are reworked and adjusted so they derive config data out of the device tree blob (instead of hard coded / tabelarized values). - This includes: LBC, PCI / PCI-Express, I2C, DS1553, OpenPIC, TSEC, SEC, QUICC, UART, CFI. - Thanks to the common FDT infrastrucutre (fdtbus, simplebus) we retire ocpbus(4) driver, which was based on hard-coded config data.
