Hi all,
I want to introduce a small patch that fixes v 2019.07 bootloader crash during
USB scan on our i.MX7 based custom board (see explanation in the patch comment).
Could you please review and add to next u-boot release?
Best regards,
Thomas

Subject: [PATCH] dts: arm: fix USB controller 'size' parameter
With introduction of bind method in ehci-mx6 driver, usb device
sequence number is calculated using the base address and size
paramters of the reg property in the usbotg and usbh nodes.
Currently the size parameter is set to 0x200 in imx7s and imx7d
dtsi files, which is wrong for i.MX7 and results in board reset
in case that more than one USB interface is used. Setting reg
to the correct value of 0x10000 will fix this issue.
