However, current init flow access the USB PHY in ehci_mx6_common_init prior than ehci_usb_phy_mode where the PHY is power up.

2018-10-25MLK-20057 usb: ehci-mx6: Fix usb type issue in DM driverYe Li
Currently the clocks and power of USB controller and USB PHY are both controlled by ehci-mx6 driver in device probe. However, the function "ehci_usb_ofdata_to_platdata" calls "ehci_usb_phy_mode" to access PHY registers when "dr_mode" is set to OTG, both "dr_mode" and "extcon" properties are not set in DTB. This may cause hang at accessing USB PHY registers if the power and clocks are not enabled. Change the usb type logic to more clear way: 1. plat->init_type: The requested USB mode type from uplayers 2. priv->init_type: The USB mode type specified by DTB or by the USB ID pin or by external controller like tcpc or GPIO. 3. If two init_type are not same, return failure. Align with non-DM driver. 4. USB PHY access is moved after power and clock enabled. Signed-off-by: Ye Li <ye.li@nxp.com>
2018-10-23MLK-20026 caam: Fix CAAM RNG init hang on imx8mq RevAYe Li
Found the imx8mq Rev A chip (B0 and B1 chips are ok) boot hang at CAAM RNG init. The jobring 0 can't complete instantiation descriptor and spins on checking ORSFR_JR0. In current implementation, the descriptor and jobring input and output base address locate on TCM, because the driver uses raw_data array in jr_data_st structure as the buffer. This seems cause the issue. If switched from TCM to OCRAM, the issue will go. Since accessing TCM by CAAM is not very reliable. Add this patch to use OCRAM for SPL case. The early malloc is ready on SPL before calling board_init_f. So we can use malloc to allocate memory instead of the raw_data array.

When running "mmc partconf" by ucmd, the PART_CONFIG EXTCSD is updated, but the part_config and hwpart variables in mmc and blk structure are not synced. So the old value will write to PART_CONFIG EXTCSD again when switch to user area. This patch changes the fastboot_setup, only load the partitions when the storage device is changed.
