	e9d5e7a Browse files » common: clock: Sample time before poller_call() ... 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.

	2603414 Browse files » ARM: i.MX: bbu: reimplement IMX_INTERNAL_FLAG_KEEP_DOSPART flag ... This patch reimplements the IMX_INTERNAL_FLAG_KEEP_DOSPART flag and makes it more generic. Until now we only kept a dos partition table over the update. Beginning with i.MX8 we may also want to preserve a GPT, so we have to extend the preserved area. It might also be the case that not (only) a partition table is stored in the initial area of a device, but also other unrelated data, so it's better to just keep the initial area that is unused by the i.MX ROM. It's also good to export the flag to allow boards to specify the initial area shall be preserved. When a board wants to set the flag for a mtd like device then it has to check for suitable erase sizes beforehand. We do not check this (yet).

	edb4379 Browse files » watchdog: rave-sp-wdt: Explicitly access EEPROM for bootsource ... RAVE SP firmware versions found on RDU2 provide decicated bootsource manipulation commands, which, under the hood, are just thin wrappers around write/read to a particular location in EEPROM. Unfortunately, RAVE SP firmware found on RDU1, does not provide any dedicated bootsource commands and its users are expected to access EEPROM directly. In order to avoid having separate code paths for handling those two cases, convert the code to access EEPROM directly via NVMEM API.

In linux, chipidea driver supports 'maximum-speed' device tree property. When that is set to "full-speed", driver sets PFSC bit in PORTSC register, which disallows use of high speed mode. This patch implements same support for barebox. Important technical detail is that PFSC bit is cleared by port reset, thus setting it has to be done in ehci->init() callback which is called after ehci_reset().
