* sunxi: Add i2c supportHans de Goede2014-07-18-0/+18
| | | | | | | | | | | | | Add support for the i2c controller found on all Allwinner sunxi SoCs, this is the same controller as found on the Marvell orion5x and kirkwood SoC families, with a slightly different register layout, so this patch uses the existing mvtwsi code.

| | | | | | | | | | | | Note this has only been tested on Allwinner sunxi devices (support for which gets introduced by a later patch). The kirkwood changes have been compile tested using the wireless_space board config, the orion5x changes have been compile tested using the edminiv2 board config.

* net: Rename and cleanup sunxi (Allwinner) emac driverStefan Roese2014-07-06-73/+69
| | | | | | | | | | | | | | | | | There have been 3 versions of the sunxi_emac support patch during its development. Somehow version 2 ended up in upstream u-boot where as the u-boot-sunxi git repo got version 3. This bumps the version in upstream u-boot to version 3 of the patch: - Initialize MII clock earlier so mii access to allow independent use - Name change from WEMAC to EMAC to match mainline kernel & chip manual - Cosmetic code cleanup Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Henrik Nordstrom <henrik@henriknordstrom.net> Signed-off-by: Oliver Schinagl <oliver@schinagl.nl> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
* sunxi: Remove mmc DMA supportHans de Goede2014-07-06-134/+7
| | | | | | | | | | | | | | | | The DMA code in sunxi_mmc.c is broken. mmc_trans_data_by_dma() allocates the dma descriptors on the stack, and then exits while the dma transfer is in progress, so the dma engine is reading stack memory which at that point may be re-used. So far we've gotten away with this by luck, but recent u-boot changes have shifted the stack start address by 16 bytes, which combined with dma alignment now exposes this problem. Since we end up just busy waiting for the dma engine anyway, this commit fixes things by simply removing the dma code, resulting in smaller bug-free code.

* gpio: spear_gpio: Fix gpio_set_value() implementationAxel Lin2014-07-04-1/+4
| | | | | | | | | | | | | | | | In current gpio_set_value() implementation, it always sets the gpio control bit no matter the value argument is 0 or 1. Thus the GPIOs never set to low. This patch fixes this bug. The address bus is used as a mask on read/write operations, so that independent software drivers can set their GPIO bits without affecting any other pins in a single write operation. Thus we don't need a read-modify-write to update the register.

* armv8/fsl-lsch3: Add support to load and start MC FirmwareJ. German Rivera2014-07-03-0/+275
| | | | | | | | | | | | | | | | Adding support to load and start the Layerscape Management Complex (MC) firmware. First, the MC GCR register is set to 0 to reset all cores. MC firmware and DPL images are copied from their location in NOR flash to DDR. MC registers are updated with the location of these images. Deasserting the reset bit of MC GCR register releases core 0 to run. Core 1 will be released by MC firmware. Stop bits are not touched for this step. U-boot waits for MC until it boots up. In case of a failure, device tree is updated accordingly. The MC firmware image uses FIT format. Signed-off-by: J.

| | | | | | | | | | | | | | Freescale LayerScape with Chassis Generation 3 is a set of SoCs with ARMv8 cores and 3rd generation of Chassis. We use different MMU setup to support memory map and cache attribute for these SoCs. MMU and cache are enabled very early to bootst performance, especially for early development on emulators. After u-boot relocates to DDR, a new MMU table with QBMan cache access is created in DDR. SMMU pagesize is set in SMMU_sACR register. Both DDR3 and DDR4 are supported.

The current allocation scheme aligns the first QTD in each pair, but simply adds the struct size to calculate the second QTD's address. This will result in a non-cache-aligned addresss IF the system's ARCH_DMA_MINALIGN is not 32 bytes (i.e. the size of struct ept_queue_item). Similarly, the original ilist_ent_sz calculation aligned the value to ARCH_DMA_MINALIGN but didn't take the USB HW's 32-byte alignment requirement into account. This doesn't cause a practical issue unless ARCH_DMA_MINALIGN < 32 (which I suspect is quite unlikely), but we may as well fix the code to be explicit, so it's obviously completely correct. The new value of ILIST_ENT_SZ takes all alignment requirements into account, so we can simplify ci_{flush,invalidate}_qtd() by simply using that macro rather than calling roundup(). Similarly, the calculation of controller.items[i] can be simplified, since each QTD is evenly spaced at its individual alignment requirement, rather than each pair being aligned, and entries within the pair being spaced apart only by structure size.

After each pair has been initialized, the pair is cache-flushed. The conversion from QH/QTD index [0..2*NUM_END_POINTS) to EP index [0..NUM_ENDPOINTS] is incorrect; it simply subtracts 1 (which yields the QH/QTD index of the first entry in the pair) rather than dividing by two (which scales the range). Fix this. On my system, this avoids cache debug prints due to requests to flush unaligned ranges. This is caused because the flush calls happen before the items[] array entries are initialized for all but EP0. Signed-off-by: Stephen Warren <swarren@nvidia.com>

Fix it to do this. Without this, when ether.c's CDC Ethernet device is torn down, eth_unbind() is never called, so dev->gadget is never set to NULL. For some reason, usb_eth_halt() is called both at the end of the first use of the Ethernet device, and prior to any subsequent use. Since dev->gadget is never cleared, all calls to usb_eth_halt() attempt to stop, disconnect, and clean up the device, resulting in double cleanup, which hangs U-Boot on my Tegra device at least. ci_udc allocates its own singleton EP0 request object, and cleans it up during usb_gadget_unregister_driver(). This appears necessary when using the USB gadget framework in U-Boot, since that does not allocate/free the EP0 request. However, the CDC Ethernet driver *does* allocate and free its own EP0 requests. Consequently, we must protect ci_ep_free_request() against double-freeing the request.

* | | dm: Cast away the const-ness of the global_data pointerSimon Glass2014-06-20-4/+4
| | | | | | | | | | | | | | | | | | | | | In a very few cases we need to adjust the driver model root device, such as when setting it up at initialisation. Add a macro to make this easier. Signed-off-by: Simon Glass <sjg@chromium.org>
* | | dm: Add missing header files in lists and rootSimon Glass2014-06-20-0/+2
| | | | | | | | | | | | | | | | | | | | | These files don't compile in some architectures. Fix it by adding the missing headers. Signed-off-by: Simon Glass <sjg@chromium.org>
* | | dm: Use case-insensitive comparison for GPIO banksSimon Glass2014-06-20-1/+1
| | | | | | | | | | | | | | | | | | | | | We want 'N0' and 'n0' to mean the same thing, so ensure that case is not considered when naming GPIO banks. Signed-off-by: Simon Glass <sjg@chromium.org>
* | | dm: Rename struct device_id to udevice_idSimon Glass2014-06-20-4/+4
| | | | | | | | | | | | | | | | | | | | | It is best to avoid having any occurence of 'struct device' in driver model, so rename to achieve this. Signed-off-by: Simon Glass <sjg@chromium.org>
* | | pmic: tps65090: correct checking i2c busJeroen Hofstee2014-06-19-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function tps65090_init checks the i2c bus of p->bus. However the pointer p is not intialiased at this point. Check the local variable bus instead. cc: Tom Wai-Hong Tam <waihong@chromium.org> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl> Acked-by: Simon Glass <sjg@chromium.org>
* | | includes: move openssl headers to include/u-bootJeroen Hofstee2014-06-19-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 18b06652cd "tools: include u-boot version of sha256.h" unconditionally forced the sha256.h from u-boot to be used for tools instead of the host version. This is fragile though as it will also include the host version. Therefore move it to include/u-boot to join u-boot/md5.h etc which were renamed for the same reason. cc: Simon Glass <sjg@chromium.org> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>
