| * mmc: extend mmcinfo output to show partition write reliability settingsDiego Santa Cruz2015-01-19-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This extends the mmcinfo hardware partition info output to show partitions with write reliability enabled with the "WRREL" string. If the partition does not have write reliability enabled the "WRREL" string is omitted; this is analogous to the ehhanced attribute. Example output: Device: OMAP SD/MMC Manufacturer ID: fe OEM: 14e Name: MMC16 Tran Speed: 52000000 Rd Block Len: 512 MMC version 4.41 High Capacity: Yes Capacity: 13.8 GiB Bus Width: 4-bit Erase Group Size: 8 MiB HC WP Group Size: 16 MiB User Capacity: 13.8 GiB ENH WRREL User Enhanced Start: 0 Bytes User Enhanced Size: 512 MiB Boot Capacity: 16 MiB ENH RPMB Capacity: 128 KiB ENH GP1 Capacity: 64 MiB ENH WRREL GP2 Capacity: 64 MiB ENH WRREL Signed-off-by: Diego Santa Cruz <Diego.SantaCruz@spinetix.com>

| | | | | | | | | | | | | | | | | | This change extends the mmc hwpartition sub-command to change the per-partition write reliability settings. It also changes the syntax used for the enhanced user data area slightly to better accomodate the write reliability option. Signed-off-by: Diego Santa Cruz <Diego.SantaCruz@spinetix.com>
| * mmc: add mmc hwpartition sub-command to do eMMC hardware partitioningDiego Santa Cruz2015-01-19-1/+92
| | | | | | | | | | | | | | | | | | Adds the mmc hwpartition sub-command to perform eMMC hardware partitioning on an mmc device. The number of arguments can be large for a complex partitioning, but as the partitioning has to be done in one go it is difficult to make it simpler.

| * mmc: show the erase group size and HC WP group size in mmcinfo outputDiego Santa Cruz2015-01-19-0/+8
| | | | | | | | | | | | | | | | | | This adds the erase group size and high-capacity WP group size to mmcinfo's output. The erase group size is necessary to properly align erase requests on eMMC. The high-capacity WP group size is necessary to properly align partitions on eMMC. Signed-off-by: Diego Santa Cruz <Diego.SantaCruz@spinetix.com>

| | | | | | | | | | | | | | | | | | The eMMC spec numbers general purpose partitions starting at 1, but the mmcinfo output follows the internal numbering which starts at 0. Make the mmcinfo command output number partitions as in the eMMC spec to avoid confusion. Signed-off-by: Diego Santa Cruz <Diego.SantaCruz@spinetix.com>
| * mmc: extend mmcinfo to show enhanced partition attributeDiego Santa Cruz2015-01-19-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This extends the mmcinfo command's output to show which eMMC partitions have the enhanced attribute set. Note that the eMMC spec says that if the enhanced attribute is supported then the boot and RPMB partitions are of the enhanced type.

| * mmc: show hardware partition sizes in mmcinfo outputDiego Santa Cruz2015-01-19-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is currently no command that will provide an overview of the hardware partitions present on an eMMC device, one has to switch to every partition via "mmc dev" and run mmcinfo for each to get the partition's capacity. This commit adds a few lines of output to mmcinfo with the sizes of the present partitions, like this: Device: OMAP SD/MMC Manufacturer ID: fe OEM: 14e Name: MMC16 Tran Speed: 52000000 Rd Block Len: 512 MMC version 4.41 High Capacity: Yes Capacity: 13.8 GiB Bus Width: 4-bit User Capacity: 13.8 GiB Boot Capacity: 16 MiB RPMB Capacity: 128 KiB GP1 Capacity: 64 MiB GP2 Capacity: 64 MiB panto: Minor edit removing superfluous parentheses.

* | musb-new: Fix reset sequence when in host modeHans de Goede2015-01-18-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit fixes a number of issues with the reset sequence of musb-new in host mode: 1) Our usb device probe relies on a second device reset being done after the first descriptors read. Factor the musb reset code into a usb_reset_root_port function (and add this as an empty define for other controllers), and call this when a device has no parent. 2) Just like with normal usb controllers there needs to be a delay after reset, for normal usb controllers, this is handled in hub_port_reset, add a delay to usb_reset_root_port. 3) Sync the musb reset sequence with the upstream kernel, clear all bits of power except bits 4-7, and increase the time reset is asserted to 50 ms. With these fixes an usb keyboard I have now always enumerates properly, where as earlier it would only enumerare properly once every 5 tries. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
* | usb: Do not log an error when no devices is plugged into a root-hub-less hcdHans de Goede2015-01-18-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit u-boot would print the following on boot with musb and no usb device plugged in: starting USB... USB0: Port not available. USB error: all controllers failed lowlevel init This commit changes this to: starting USB... USB0: Port not available. Which is the correct thing to do since the low-level init went fine. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
* | usb: Fix usb_kbd_deregister when console-muxing is usedHans de Goede2015-01-18-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | When iomuxing is used we must not only deregister the device with stdio.c, but also remove the reference to the device in the console_devices array used by console-muxing. Add a call to iomux_doenv to usb_kbd_deregister to update console_devices, which will drop the reference. This fixes the console filling with "Failed to enqueue URB to controller" messages after a "usb stop force", or when the USB keyboard is gone after a "usb reset".

| | | | | | | | | | | | | | | | Currently create_int_queue is only implemented by the ehci code, and that does not honor interrupt intervals, but other drivers which might also want to implement create_int_queue may honor intervals, so add an interval param.

* | USB: make "usb start" start usb only onceHans de Goede2015-01-18-17/+31
|/ | | | | | | | | | | | | | | | | | Currently we've this magic in include/config_distro_bootcmd.h to avoid scanning the usb bus multiple times. And it does not work when also using an usb keyboard because then the preboot command has already scanned the bus, so we're still scanning it twice. This commit makes "usb start" only start usb if it is no already started, allowing us to remove all the magic for it from include/config_distro_bootcmd.h and just call it unconditionally. This also causes "usb start" and "usb reset" to actually do what their different names suggest, rather then both of them doing exactly the same. Signed-off-by: Hans de Goede <hdegoede@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the pre-console buffer can accumulate early log messages and flush them to the serial console as soon as it becomes available. This patch just adds one more pre-console buffer flushing point and does all the same for the other consoles too. This is particularly useful for the vga/hdmi/lcd console, where we can see all the older messages now (except for the log messages from SPL). Naturally, we don't want to get an extra copy of the log messages on the serial console again at the second flushing point, so the serial console has to be explicitly filtered out.

| * ARM: Implement non-cached memory supportThierry Reding2014-12-18-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement an API that can be used by drivers to allocate memory from a pool that is mapped uncached. This is useful if drivers would otherwise need to do extensive cache maintenance (or explicitly maintaining the cache isn't safe). The API is protected using the new CONFIG_SYS_NONCACHED_MEMORY setting. Boards can set this to the size to be used for the non-cached area. The area will typically be right below the malloc() area, but architectures should take care of aligning the beginning and end of the area to honor any mapping restrictions. Architectures must also ensure that mappings established for this area do not overlap with the malloc() area (which should remain cached for improved performance). While the API is currently only implemented for ARM v7, it should be generic enough to allow other architectures to implement it as well.
