* cmd: Fix license commandTom Rini2016-03-22-8/+15
| | | | | | | | | | | | The license command isn't usually built and has a few problems: - The rules to generate license.h haven't worked in a long time, re-write these based on the bmp_logo.h rules. - 'tok' is unused and the license text size has increased - bin2header.c wasn't grabbing unistd.h to know the prototype for read().

* serial: pl01x: Add support for devices with the rate pre-configured.Eric Anholt2016-03-22-3/+12
| | | | | | | | | | | | | For Raspberry Pi, we had the input clock rate to the pl011 fixed in the rpi.c file, but it may be changed by firmware due to user changes to config.txt. Since the firmware always sets up the uart (default 115200 output unless the user changes it), we can just skip our own uart init to simplify the boot process and more reliably get serial output.

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.
