| * | common: clock: Sample time before poller_call()Andrey Smirnov2018-07-021-1/+3
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change is_timeout() to sample current time before invoking poller infrascructure to avoid occasional false timeout conditions. Consider the following timeout loop (can be found in wait_on_timeout): while (!(condition)) { if (is_timeout(...)) { return -ETIMEDOUT; } } ... in the original logic of is_timeout() it was possible to end up in the following situation: 1. Immediate check of of "condition" yeilds false (not enough time for it to become true has passed yet) 2. is_timeout is called which, in turn, calls poller_call() 3. All registerd pollers take more than specified timeout time to execute. 4. Sometime during poller_call() "contition" becomes true 5. As a result of #3 is_timeout() returns "true" 6. Code bails out with -ETIMEDOUT early even though timeout condition didn't really occur. One concrete example of this problem was discovered on ZII RDU1 board (poller_call() is long due to a serdev) when doing large data transfers over SPI to attached DataFlash chip. This commit changes is_timeout() to sample the value of time before calling poller_call(). This way first call to is_timeout() will almost always return false thus checking the condition at least twice before declaring a timeout.

| * bootm: Split bootm_load_devicetree into two functionsSascha Hauer2018-06-151-26/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | It is not always desired to get the devicetree from image data and load it to a SDRAM region at the same time. Sometimes it's enough to just load it to an allocated address (in case the user has no constraints where the devicetree should be placed. This patch splits bootm_load_devicetree into bootm_get_devicetree which returns a pointer to the allocated devicetree and bootm_load_devicetree which loads the devicetree to a specified region.

| * | serdev: Allow polling interval to be adjusted at runtimeAndrey Smirnov2018-04-171-1/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to blocking, synchronous, polling driven nature of Barebox's serial communication handling trying to use two or more serial ports at high (1Mbaud+) baudrates results in data loss and noticeable perofmance degradation. This happens as soon as individual message being sent around start exceeding HW Rx FIFO in size. A good example of such a usecase would be using a system that has a serdev driver (operating @ 1Mbaud+) and trying to do a X/YMODEM transfer via serial console at comparable baudrates. To at least partially ameliorate the problem, add code that will expose "polling_interval" as a parameter, so that the user would have an option of temporarily disabling (or significatly decreasing the rate) of a given serdev's polling.
