| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recently the ext4 file system imposed passing absolute path with its file name parameter. As a result dfu_alt_info env variable has been modified to provide absolute path when ext4 file system is accessed (e.g. /uImage ext4 0 2;). Unfortunately, lthor flashing program provides plain file name (like uImage) and hence those two file names do not match anymore.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | usb_phy_enable should return status bit, but not phy mode bit, thus add a new function usb_phy_mode to query the PHY for it's mode and make usb_phy_enable just return 0 but not 'phy_ctrl & USBPHY_CTRL_OTG_ID'. Include a new board weak function board_usb_phy_mode. If board code does not reimplement this function, it just call usb_phy_mode and return usb_phy_mode's return value. The reason to include such a weak function is: " SOC OTG core <--connect--> board HOST port, but no pin id for the board host port, so board can not use usb_phy_mode to return the phy mode, but define it's own rule."

After enabling the thermal driver on a mx6sxsabresd board: U-Boot 2015.01-rc1-18267-g99d4189-dirty (Nov 24 2014 - 12:59:01) CPU: Freescale i.MX6SX rev1.0 at 792 MHz CPU: Temperature 48 C Reset cause: POR Board: MX6SX SABRE SDB I2C: ready DRAM: 1 GiB PMIC: PFUZE100 ID=0x10 MMC: FSL_SDHC: 0, FSL_SDHC: 1, FSL_SDHC: 2 00:01.0 - 16c3:abcd - Bridge device 01:00.0 - 8086:08b1 - Network controller In: serial Out: serial Err: serial Net: (hang) As the thermal driver accesses the ocotp registers, its clock will be disabled afterwards. Then when the MAC address is read (also from ocotp registers) it will cause a hang. Do not disable the ocotp clock to prevent this problem.
