From: Fabio Estevam <fabio.estevam@xxxxxxxxxxxxx> There is only one mx21 based hardware currently supported in the kernel: arch/arm/mach-imx/mach-mx21ads.c. mx21ads does not register the USB host driver, which makes imx21-hcd to not have any user. There have been some patches recently adding device tree support to mx21. If someone in the future still gets interested in using USB on mx21, then the chipidea driver could be used instead. So let's remove the unused imx21-hcd driver.
