* usb: Change power-on / scanning timeout handlingStefan Roese2016-03-20-94/+223
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the USB port scanning procedure and timeout handling in the following ways: a) The power-on delay in usb_hub_power_on() is now reduced to a value of max(100ms, "hub->desc.bPwrOn2PwrGood * 2"). The code does not wait using mdelay, instead usb_hub_power_on() will wait before querying the device in the scanning loop later. The total timeout for this hub, which is 1 second + "hub->desc.bPwrOn2PwrGood * 2" is calculated and will be used in the following per-port scanning loop as the timeout to detect active USB devices on this hub. b) Don't delay the minimum delay (for power to stabilize) in usb_hub_power_on(). Instead skip querying these devices in the scannig loop until the delay time is reached. c) The ports are now scanned in a quasi parallel way. The current code did wait for each (unconnected) port to reach its timeout and only then continue with the next port. This patch now changes this to scan all ports of all USB hubs quasi simultaneously. For this, all ports are added to a scanning list. This list is scanned until all ports are ready by either a) reaching the connection timeout (calculated earlier), or by b) detecting a USB device. This results in a faster USB scan time as the recursive scanning of USB hubs connected to the hub that's currently being scanned will start earlier. One small functional change to the original code is, that ports with overcurrent detection will now get rescanned multiple times (PORT_OVERCURRENT_MAX_SCAN_COUNT). Without this patch: starting USB... USB0: USB EHCI 1.00 scanning bus 0 for devices... 9 USB Device(s) found time: 20.163 seconds With this patch: starting USB... USB0: USB EHCI 1.00 scanning bus 0 for devices... 9 USB Device(s) found time: 1.822 seconds So ~18.3 seconds of USB scanning time reduction.

* usb: Don't reset the USB hub a 2nd timeStefan Roese2016-03-20-12/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Debugging has shown, that all USB hubs are being reset twice while USB scanning. This introduces additional delays and makes USB scanning even more slow. Testing has shown that this 2nd USB hub reset doesn't seem to be necessary. This patch now removes this 2nd USB hub reset. Resulting in faster USB scan time. Here the current numbers: Without this patch: => time usb start starting USB... USB0: USB EHCI 1.00 scanning bus 0 for devices... 9 USB Device(s) found time: 24.003 seconds With this patch: => time usb start starting USB...

* efi_loader: Implement memory allocation and mapAlexander Graf2016-03-15-0/+3
| | | | | | | | | | | | | | | | | | | The EFI loader needs to maintain views of memory - general system memory windows as well as used locations inside those and potential runtime service MMIO windows. To manage all of these, add a few helpers that maintain an internal representation of the map the similar to how the EFI API later on reports it to the application. For allocations, the scheme is very simple. We basically allow allocations to replace chunks of previously done maps, so that a new LOADER_DATA allocation for example can remove a piece of the RAM map. When no specific address is given, we just take the highest possible address in the lowest RAM map that fits the allocation size.

| | | | | | | | | | | | | | | | | After booting has finished, EFI allows firmware to still interact with the OS using the "runtime services". These callbacks live in a separate address space, since they are available long after U-Boot has been overwritten by the OS. This patch adds enough framework for arbitrary code inside of U-Boot to become a runtime service with the right section attributes set. For now, we don't make use of it yet though. We could maybe in the future map U-boot environment variables to EFI variables here.
