Make it possible to access the ocotp registers before the ocotp device is attached, by establishing a temporary mapping of the registers when necessary. It turns out Freescale cleverly made the ocotp device compatible across several different families of SoCs, so move it to the freescale directory and prefix everything with fsl rather than imx6. Convert the imx6 sdhci "R1B fix" from a busy-loop in the interrupt handler to a callout. Increase the wait time for acquiring the SD bus from 10 to 250ms. If no compatible cards were found after probing the SD bus, say so. Add timeout logic to sdhci, separate from the timeouts done by the hardware. After a timeout, reset the controller using SDHCI_RESET_CMD|SDHCI_RESET_DATA rather than SDHCI_RESET_ALL; the latter turns off clocks and power, removing any possibility of recovering from the error. Add a helper routine to depth-search the device tree for a node with a matching 'compatible' property. Notes: svn path=/stable/10/; revision=266200

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | r261596, r261606 Add the imx sdhci controller. Move Open Firmware device root on PowerPC, ARM, and MIPS systems to a sub-node of nexus (ofwbus) rather than direct attach under nexus. This fixes FDT on x86 and will make coexistence with ACPI on ARM systems easier. SPARC is unchanged. Add the missing ')' at end of sentence. Reword it to use a more common idiom. Pass the kernel physical address to initarm through the boot param struct. Make functions only used in vfp.c static, and remove vfp_enable. Fix __syscall on armeb EABI. As it returns a 64-bit value it needs to place 32-bit data in r1, not r0. 64-bit data is already packed correctly. Use abp_physaddr for the physical address over KERNPHYSADDR. This helps us remove the need to load the kernel at a fixed address. Remove references to PHYSADDR where it's used only in debugging output. Dynamically generate the page table. This will allow us to detect the physical address we are loaded at to change the mapping. Notes: svn path=/stable/10/; revision=266160

| | | | | | | | | mode. We don't know why it failed, so we can't know that a retry will also fail (the low-level driver might have reset the controller state machine or something similar that would allow a retry to work). Notes: svn path=/head/; revision=254716
* Make the standard sdhci(4) driver work for the TI OMAP family SoCs.Ian Lepore2013-08-201-0/+1
| | | | | | | | | | | | | | | | | The MMCHS hardware is pretty much a standard SDHCI v2.0 controller with a couple quirks, which are now supported by sdhci(4) as of r254507. This should work for all TI SoCs that use the MMCHS hardware, but it has only been tested on AM335x right now, so this enables it on those platforms but leaves the existing ti_mmchs driver in place for other OMAP variants until they can be tested. This initial incarnation lacks DMA support (coming soon). Even without it this improves performance pretty noticibly over the ti_mmchs driver, primarily because it now does multiblock IO.

* Consistently init all mmc request, command, and data structures to zeroIan Lepore2013-08-172-10/+27

* Handle command retries for commands originating at the mmc layer, andIan Lepore2013-08-161-32/+41
| | | | | | | | | | | | | | | | | | | | | | | ensure that all such commands have a non-zero retry count except for those that are expected to fail (for example, because they are used to probe for feature support). While it is possible to pass a retry count down to the hardware driver in the command request structure, no hardware driver currently implements any retry logic. The hardware doesn't know much about the context of a single request, so it makes more sense to handle retries at a layer that does. This adds retry loops to the mmc_wait_for_cmd() and mmc_wait_for_app_cmd() functions. These functions are the gateway from other code within mmc.c to the hardware. App commands are a sequence of two commands and a retry has to rerun both of them in order, so it needs its own retry loop. Retry looping is specifically NOT implemented in mmc_wait_for_request() because it is the gateway for children on the bus, and they have to implement their own retry logic depending on what makes sense for them.

* o Fixes:Marius Strobl2012-04-215-33/+89
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | - When switching to 4-bit operation, send a SET_CLR_CARD_DETECT command to disconnect the card-detect pull-up resistor from the DAT3 line before sending the SET_BUS_WIDTH command. - Add the missing "reserved" zero entry to the mantissa table used to decode various CSD fields. This was causing SD cards to report that they could run at 30 MHz instead of the maximum 25 MHz mandated in the spec. o Enhancements: - At the MMC layer, format various info from the CID into a string that uniquely identifies the card instance (manufacturer number, serial number, product name and revision, etc). Export it as an instance variable. - At the MMCSD layer, display the formatted card ID string, and also report the clock speed of the hardware (not the card's max speed), and the number of bits and number of blocks per transfer. It comes out like this now: mmcsd0: 968MB <SD SD01G 8.0 SN 276886905 MFG 08/2008 by 3 SD> at mmc0 22.5MHz/4bit/128-block o Use DEVMETHOD_END. o Use NULL instead of 0 for pointers.

* Make the newbus subsystem Giant free by adding the new newbus sxlock.Attilio Rao2009-08-021-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The newbus lock is responsible for protecting newbus internIal structures, device states and devclass flags. It is necessary to hold it when all such datas are accessed. For the other operations, softc locking should ensure enough protection to avoid races. Newbus lock is automatically held when virtual operations on the device and bus are invoked when loading the driver or when the suspend/resume take place. For other 'spourious' operations trying to access/modify the newbus topology, newbus lock needs to be automatically acquired and dropped. For the moment Giant is also acquired in some key point (modules subsystem) in order to avoid problems before the 8.0 release as module handlers could make assumptions about it. This Giant locking should go just after the release happens. Please keep in mind that the public interface can be expanded in order to provide more support, if there are really necessities at some point and also some bugs could arise as long as the patch needs a bit of further testing. Bump __FreeBSD_version in order to reflect the newbus lock introduction. Reviewed by: ed, hps, jhb, imp, mav, scottl No answer by: ariff, thompsa, yongari Tested by: pho, G.

To reinitialize card on resume and to detect card change while suspended, implement bus rescan routines. It can also be used by controllers without card presence detection signals or with multiple cards per slot support. While there, cleanup msleep() usage.

* Implement BIO_DELETE command with MMC and SD erase commands.Alexander Motin2008-10-184-149/+333
| | | | | | | | | | | | | | | | | | | | Erase operation gives card's logic information about unused areas to help it implement wear-leveling with lower overhead comparing to usual writing. Erase is much faster then write and does not depends on data bus speed. Also as result of hitting in-card write logic optimizations I have measured up to 50% performance boost on writing undersized blocks into preerased areas. At the same time there are strict limitations on size and allignment of erase operations. We can erase only blocks aligned to the erase sector size and with size multiple of it. Different cards has different erase sector size which usually varies from 64KB to 4MB. SD cards actually allow to erase smaller blocks, but it is much more expensive as it is implemented via read-erase-write sequence and so not sutable for the BIO_DELETE purposes.
