tegra: usb: Fix device enumeration problem of USB1

A known hardware issue of USB1 port where bit 1 (connect status
change) of PORTSC register will be set after issuing Port Reset
(like "usb reset" in u-boot command line).
This will be treated as an error and stops later device enumeration.

Therefore we clear that bit after Port Reset in order to proceed
later device enumeration.

colibri_t20: disable PMIC sleep mode on low supply voltage 2014-03-16T11:48:09+00:00 Marcel Ziswiler marcel.ziswiler@toradex.com 2014-03-16T11:48:09+00:00 ccd521c4681a5850bbec1feec140eeaec33936b0 The Colibri T20's PMIC enters a sleep mode on low supply voltage < 3.0V ±2.5% (2.92...3.08V). Rising the main supply voltage again does not bring it back to regular operation. Not even a full reset does bring the module back. A full power cycle was required to reboot the system. A long positive pulse on the PMICs resume pin also reboots the system but this pin is only accessible as a test point on the module. This patch configures the PMIC through I2C to not enter this sleep mode plus force it to normal state upon sleep request exit should this ever happen.

apalis/colibri_t20/30: hw boot partition support 2014-03-12T13:28:19+00:00 Marcel Ziswiler marcel.ziswiler@toradex.com 2014-03-12T13:28:19+00:00 7b6d69722c0b3ccc25df1eaffa7c1c3052223e00 The new production lot of Apalis T30 2GB V1.0C now features the new SK Hynix H26M42003GMR rather than Hynix H26M42002GMR. Even though both chips feature the same silicon they differ in respective eMMC firmware and therefore have a different hardware boot partition layout. This patch enables hardware boot partition support (via 'mmc dev [dev] [part]' command) and handles NVIDIA's proprietary NvFlash/Fastboot\ behaviour now putting their partition table in the second boot partition rather than the regular user area. While at it also get rid of the spurious 'video=tegrafb' kernel boot argument, adjust the optional ubiargs and add 'noatime' to the usbargs.
