net: Add ethernet FCS length macro in net.h

2015-03-25T03:22:37Z

Some ethernet drivers use their own version of ethernet FCS length macro which is really common. We define ETH_FCS_LEN in net.h and replace those custom versions in various places. Signed-off-by: Bin Meng Acked-by: Joe Hershberger

fastboot: OUT transaction length must be aligned to wMaxPacketSize

2015-02-25T16:47:02Z

OUT transactions must be aligned to wMaxPacketSize for each transfer, or else transfer will not complete successfully. This patch modifies rx_bytes_expected to return a transfer length that is aligned to wMaxPacketSize. Note that the value of wMaxPacketSize and ep->maxpacket may not be the same value, and it is the value of wMaxPacketSize that should be used for alignment. wMaxPacketSize is passed depending on the speed of connection.

usb: gadget: fastboot: Add fastboot erase

2015-02-25T16:47:02Z

Adds the fastboot erase functionality, to erase a partition specified by name. The erase is performed based on erase group size, to avoid erasing other partitions. The start address and the size is aligned to the erase group size for this. Currently only supports erasing from eMMC. Signed-off-by: Dileep Katta Reviewed-by: Lukasz Majewski

fastboot: add support for "oem format" command

2015-02-25T16:47:02Z

Add "oem format" command to write partition table. This relies on the env variable partitions to contain the list of partitions as required by the gpt command. Note that this does not erase any data other than the partition table. Signed-off-by: Rob Herring Reviewed-by: Steve Rae

fastboot: add "fastboot oem" command support

2015-02-25T16:47:02Z

Add code stub to handle "fastboot oem __" command. As unlock is a common fastboot command, distinguish that it is not implemented. Signed-off-by: Michael Scott Signed-off-by: Rob Herring Tested-by: Steve Rae

usb: gadget: pxa25x_udc: fix use-before-initialized bug

2015-01-18T11:31:01Z

Fix use-before-initialized bug in pxa25x_udc driver. Function usb_gadget_register_driver calls udc_disable, and udc_disable calls pullup_off that uses dev->mach->udc_command. But dev->mach is initialized in usb_gadget_register_driver after calling udc_disable. This patch fixes the order of initialization. Signed-off-by: Alex Sadovsky

usb: gadget: f_dfu: Add get_alt function to pass the USB compliance test

2015-01-18T11:31:00Z

Without this function the USB compliance test (USB 2.0 Command Verifier) will fail in the "Interface Descriptor Test" with this error message: FAIL (1.2.51) A successful GetInterface request must return the alternate setting set by a prior call to SetInterface. Lets add this function to read back the value so that the DFU device fully passes the USB compliance test.

usb: gadget: composite: Fix NULL pointer crash in USB compliance test

2015-01-18T11:31:00Z

On the DXR2 board (AM335x using MUSB) the USB compliance test suite (USB 2.0 Command Verifier) will cause the board to crash and reset upon the "BOS Descriptor Test - Addressed state". Here the output from the DRX2 while running this test: GADGET DRIVER: usb_dnl_dfu musb-hdrc: peripheral reset irq lost! composite_setup (776) data abort pc : [<87f693ac>] lr : [<87f6911c>] sp : 86f33a58 ip : 00000000 fp : 86f3bbac r10: 00000f00 r9 : 86f33ef4 r8 : 86f37da8 r7 : 00000005 r6 : 86f33a90 r5 : 00000000 r4 : 86f37e30 r3 : 00000000 r2 : 00000000 r1 : 87f9c888 r0 : 00000016 Flags: Nzcv IRQs off FIQs on Mode SVC_32 Resetting CPU ... resetting ... By adding the case statement for USB_DT_BOS and therefore not running into the default case (jump to unkown label) this crash is fixed.

gadget: f_thor: check pointers before use in download_tail()

Some pointers in function download_tail() were not checked before the use. This could possibly cause the data abort. To avoid this, check if the pointers are not null is added. Signed-off-by: Przemyslaw Marczak Tested-by: Lukasz Majewski [TestHW: Exynos4412-Trats2]
