2016-05-20add init_mainbus() hooks for the other armv7 platformsJonathan Gray
2016-05-07set the high speed enable bit if the timing isn't SDMMC_TIMING_LEGACYJonathan Gray

2016-05-05Add Dual Data Rate support for eMMC at 52MHz.Mark Kettenis
2016-05-02Add check to armv7 platform bus match code, so that those busses onlyPatrick Wildt
attach if we are running in legacy mode. ok jsg@
2016-05-02Rework mainbus and implement simplebus to be able to span a tree-likePatrick Wildt

2016-05-01Add support for changing the bus width to the sdmmc subsystem and the sdhc(4)Mark Kettenis
controller. Use this to switch SD cards to a 4-bit bus if they support it. ok deraadt@, jsg@

2016-03-02Detect and only enable the port that is actually used.Can Erkin Acar
The unused port, if enabled, fills up and triggers flow control, blocking transmit and causing device timeouts. Also enable interrupt pacing to limit interrupts at 2K/s. Reported and fix tested by Anthony Eden. ok dlg@

2016-01-31Switch from PSR_X_bit and X32_bit PSR macro names to just PSR_X.Jonathan Gray
This matches FreeBSD and makes things a bit more consistent. Discussed with Patrick.
2016-01-10Seems the voltage bit defenitions in sdmmcreg.h for voltages below 2VMark Kettenis
are not quite right. At least I can't find them in any of the MMC and SD card documentation I can find on the interwebs. Instead there is a single "low voltage bit" that indicates support for the 1.65-1.95V or 1.70-1.95V range depending on the document you're reading. Go with the 1.65-1.95V range as that is what Linux does. Necessary (but not sufficient) to make the eMMC on the ASUS X205TA work. ok jsg@ (who did the armv7 bits)

2015-11-25Small fixes related to the IFF_OACTIVE removal.Martin Pieuchot
2015-11-25replace IFF_OACTIVE manipulation with mpsafe operations.David Gwynne
there are two things shared between the network stack and drivers in the send path: the send queue and the IFF_OACTIVE flag. the send queue is now protected by a mutex. this diff makes the oactive functionality mpsafe too. IFF_OACTIVE is part of if_flags. there are two problems with that. firstly, if_flags is a short and we dont have any MI atomic operations to manipulate a short. secondly, while we could make the IFF_OACTIVE operates mpsafe, all changes to other flags would have to be made safe at the same time, otherwise a read-modify-write cycle on their updates could clobber the oactive change. instead, this moves the oactive mark into struct ifqueue and provides an API for changing it. there's ifq_set_oactive, ifq_clr_oactive, and ifq_is_oactive. these are modelled on ifsq_set_oactive, ifsq_clr_oactive, and ifsq_is_oactive in dragonflybsd. this diff includes changes to all the drivers manipulating IFF_OACTIVE to now use the ifsq_{set,clr_is}_oactive API too. ok kettenis@ mpi@ jmatthew@ deraadt@
2015-11-12get rid of IFQ_POLL.David Gwynne
IFQ_POLL(&ifp->if_snd, m); if (m == NULL) return; IFQ_DEQUEUE(&ifp->if_snd, m); is the same as IFQ_DEQUEUE(&ifp->if_snd, m); if (m == NULL) return; ok mpi@

multiple socs. From Patrick Wildt in bitrig with some additional changes.
2015-05-19use the same va entry point on all armv7 socsJonathan Gray
Similiar changes were made in bitrig by Patrick Wildt. As part of this change the physical load address for imx and sunxi have changed. Any u-boot settings that include it will need to be modified. imx: 0x10800000 -> 0x10300000 sunxi: 0x40800000 -> 0x40300000 Tested by bmercer, canacar and myself. ok bmercer@
2015-05-15Make board attaching table driven and move it out into the socJonathan Gray
directories. Move the device tables while here as was done in bitrig. With these changes the only use of the board id defines is in the soc directories. Tested by matthieu and djm on imx and myself on omap and sunxi (qemu). ok djm@, ok jasper@ on an earlier version

2014-11-01Now the armv7 ramdisks are compiled with SMALL_KERNELJonathan Gray
the omap and sunxi ramdisks won't build because they call wdog_register() and kern_watchdog.c is !small_kernel in config. Leaving the watchdog devices out of the ramdisks won't work either as armv7_machdep.c uses platform_watchdog_reset() to reboot. Deal with this by only calling wdog_register() when not compiled with SMALL_KERNEL.

the code present in omap/omap.c imx/imx.c and sunxi/sunxi.c All this code looks quite the same, so we move it in a generic armv7/armv7.c This is a step closer to only one kernel for all armv7 boards. ok patrick@, rapha@
