* dfu: dfu_get_buf: check the value of env dfu_bufsiz before usePrzemyslaw Marczak2014-12-181-2/+6
| | | | | | | | | | | | | | | | | | | In function dfu_get_buf(), the size of allocated buffer could be defined by the env variable. The size from this variable was passed for memalign() without checking its value. And the the memalign will return non null pointer for size 0. This could possibly cause data abort, so now the value of var is checked before use. And if this variable is set to 0 then the default size will be used. This commit also changes the base passed to simple_strtoul() to 0. Now decimal and hex values can be used for the variable dfu_bufsiz.

| | | | | | | | | | | The function mmc_block_op() is the last function before the physicall data write, but the mmc device pointer is not checked. If mmc device not exists, then data abort will occur. To avoid this, first the mmc device pointer is checked.

* fastboot: add support for continue commandRob Herring2014-12-181-0/+14
| | | | | | | | | | | | The fastboot continue command is defined to exit fastboot and continue autoboot. This commit implements the continue command and the exiting of fastboot only. Subsequent u-boot commands can be processed after exiting fastboot. Autoboot should implement a boot script such as "fastboot; mmc read <...>; bootm" to fully implement the fastboot continue function.

* USB: gadget: atmel_usba_udc: fix transfer hang issueBo Shen2014-12-161-1/+0
| | | | | | | | | | | | | When receive data, the RXRDY in status register set by hardware after a new packet has been stored in the endpoint FIFO. After, we copy from FIFO, we clear it, make the FIFO can be accessed again. In the receive_data() function, this bit RXRDY has been cleared. So, after the receive_data() function return, this bit should not be cleared again, or else it will cause the accessing FIFO corrupt, which will make the data loss.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the MMC_MODE_DDR_52MHz flag is set in card capabilities bitmask, it is never cleared, even if switching to DDR mode fails, and if the controller driver uses this flag to check the DDR mode, it can take incorrect actions. Also, DDR related checks in mmc_startup() incorrectly handle the case when the host controller does not support some bus widths (e.g. can't support 8 bits), since the host_caps is checked for DDR bit, but not bus width bits. This fix clearly separates using of card_caps bitmask, having there the flags for the capabilities, that the card can support, and actual operation mode, described outside of card_caps (i.e. bus_width and ddr_mode fields in mmc structure). Separate host controller drivers may need to be updated to use the actual flags. Respectively, the capabilities checks in mmc_startup are made more correct and clear. Also, some clean up is made with errors handling and code syntax layout. Signed-off-by: Andrew Gabbasov <andrew_gabbasov@mentor.com>
