Ever since the block layer expanded its command syntax beyond justBIO_READ and BIO_WRITE, we've handled this expanded syntax poorly indrivers when the driver doesn't support a particular command. Do asweep and fix that.Reported by: imp List of files: /freebsd-13.1/sys/dev/flash/mx25l.c

Use the new FDTCOMPAT_PNP_INFO() macro to define SPIBUS_FDT_PNP_INFO().Also rename SPIBUS_PNP_INFO -> SPIBUS_FDT_PNP_INFO because there could beother kinds of pnpinfo for other (non-fdt) bus attachments. List of files: /freebsd-13.1/sys/dev/flash/mx25l.c

Sun, 10 Mar 2019 18:48:08 +0000

Give the mx25l device sole ownership of the name /dev/flash/spi* instead oftrying to use disk_add_alias() to make spi* an alias for mx25l*. It turnsout disk_add_alias() works for partitions, but not slices, and that's hardto fix.This change is, in effect, a partial revert of r344526.The mips world relies on the existence of flashmap names formatted as/dev/flash/spi0s.name, whereas pretty much nothing relies on at45d devicesusing the /dev/spi* names (because until recently the at45d driver didn'teven work reliably). So this change makes mx25l devices the sole owner ofthe /dev/flash/spi* namespace, which actually makes some sense because it isa SpiFlash(tm) device, so flash/spi isn't a horrible name.Reported by: Mori Hiroki List of files: /freebsd-13.1/sys/dev/flash/mx25l.c

d3248c41 - Resolve a name conflict when both SpiFlash and DataFlash devices are present.

Mon, 25 Feb 2019 17:30:01 +0000

Resolve a name conflict when both SpiFlash and DataFlash devices are present.Both SpiFlash (mx25l) and DataFlash (at45d) drivers create a disk devicewith a name of /dev/flash/spiN where N is the driver's unit number. Ifboth types of devices are present in the same system, this creates a fatalconflict that prevents attachment of whichever device attaches second(because mx25l0 and at45d0 both try to create a spi0).This gives each type of device a unique name (mx25lN or at45dN respectively)and also adds an alias of spiN for compatibility. When both device typesappear in the same system, only the first to attach gets the spiN alias.When the second device attaches there is a non-fatal warning that the aliascan't be created, but both devices are still accessible via their primarynames (and there is no need for the spiN name to work for backwardscompatibility on such a system, because it has never been possible to usethe spiN names when both devices exist).

Sun, 18 Mar 2018 16:52:31 +0000

Bugfix: wait for writes/erases to complete after starting them, instead ofbefore starting them.Using the wait-before logic would make sense if there was useful time-consuming work that could be done between the end of one write and thebeginning of the next, but it also requires doing the wait-for-ready beforereading, because a prior write or erase could still be in progress. Readingis the far more common case, so adding a whole extra bus transaction tocheck for ready before each read would soak up any small gains that might behad from doing async writes.
