* ARM: bcm2835: use phys_to_bus() for mboxStephen Warren2015-04-14-2/+3
| | | | | | | | When we communicate with the VideoCore to perform property mailbox transactions, that is a DMA operation as far as the property buffer is concerned. Use phys_to_bus() on that buffer. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>

* ARM: bcm2835: implement phys_to_bus/bus_to_physStephen Warren2015-04-14-1/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The BCM283[56] contain both a L1 and L2 cache between the GPU (a/k/a VideoCore CPU?) and DRAM. DMA-capable peripherals can also optionally access DRAM via this same L2 cache (although they always bypass the L1 cache). Peripherals select whether to use or bypass the cache via the top two bits of the bus address. An IOMMU exists between the ARM CPU and the rest of the system. This controls whether the ARM CPU's accesses use or bypass the L1 and/or L2 cache. This IOMMU is configured/controlled exclusively by the VideoCore CPU. In order for DRAM accesses made by the ARM core to be coherent with accesses made by other DMA peripherals, we must program a bus address into those peripherals that causes the peripheral's accesses to use the same set of caches that the ARM core's accesses will use. On the RPi1, the VideoCore firmware sets up the IOMMU to enable use of the L2 cache. This corresponds to addresses based at 0x40000000. On the RPi2, the VideoCore firmware sets up the IOMMU to disable use of the L2 cache. This corresponds to addresses based at 0xc0000000. This patch implements U-Boot's phys_to_bus/bus_to_phys APIs according to those rules. For full details of this setup, please see Dom Cobley's description at: http://lists.denx.de/pipermail/u-boot/2015-March/208201.html http://permalink.gmane.org/gmane.comp.boot-loaders.u-boot/215038 https://www.mail-archive.com/u-boot@lists.denx.de/msg166568.html Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
* Create API to map between CPU physical and bus addressesStephen Warren2015-04-14-0/+33
| | | | | | | | | | | | | On some SoCs, DMA-capable peripherals see a different address space to the CPU's physical address space. Create an API to allow platform-agnostic drivers to convert between the two address spaces when programming DMA operations. This API will exist on all platforms, but will have a dummy implementation when this feature is not required. Other platforms will enable CONFIG_PHYS_TO_BUS and provide the required implementation.

* usb: dwc2: fix bulk transfersStephen Warren2015-04-14-9/+13
| | | | | | | | | | | | | | | | When I created wait_for_chhltd(), I noticed that some instances of the code it replaced expected the ACK bit to be set and others didn't. I assumed this was an accidental inconsistency in the code, so wrote wait_for_chhltd() to always expect ACK to be set. This code appeared to work correctly for both enumeration of USB keyboards and operation of USB Ethernet devices. However, this change broke USB Mass Storage (at least my USB SD card reader). This change reverts to exactly the original behaviour. I'm not sure why the ACK bit isn't always set (perhaps a quirk in the USB HW or DWC2 controller), but the code works this way!

* usb: dwc2: remove restriction on buffer lengthStephen Warren2015-04-14-9/+3
| | | | | | | | | | Each USB transfer is split up into chunks that are held in an aligned buffer. This imposes a limit on the size of each chunk, but no limit on the total size of transferred data. Fix the logic in chunk_msg() not to reject large transfers, but simply take the size of the aligned buffer into account when calculating the chunk size.

* usb: dwc2: fix aligned buffer usageStephen Warren2015-04-14-6/+8
| | | | | | | | | | | | | | | The original aligned_buffer usage: a) Uselessly copied data into the aligned buffer even for IN transactions. Fix this my making the copy conditional. b) Always programmed the HW to transfer to/from the start of the aligned buffer. This worked fine for OUT transactions since the memcpy copied the OUT data to this location too. However, for large IN transactions, since the copy from the aligned buffer to the "client" buffer was deferred until after all chunks were transferred. it resulted in each chunk's transfer over-writing the data for the first transfer. Fix this by copying IN data as soon as it's received. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>

* usb: fix first descriptor fetch error handlingStephen Warren2015-04-14-1/+16
| | | | | | | | | | | | | | | | | | When fetching the first descriptor from a new device, only validate that we received at least 8 bytes, not that we received the entire descriptor. The reasoning is: - The code only uses fields in the first 8 bytes, so that's all we need to have fetched at this stage. - The smallest maxpacket size is 8 bytes. Before we know the actual maxpacket the device uses, the USB controller may only accept a single packet (see the DWC2 note in the comment added in the commit). Consequently we are only guaranteed to receive 1 packet (at least 8 bytes) even in a non-error case.

| | | | | | | | This may happen when using an USB1 device on a controller that only supports USB2 (e.g. EHCI).
