[PATCH v2 0/6] Add fastboot support for MediaTek mt8518

[PATCH v2 0/6] Add fastboot support for MediaTek mt8518

[mingming lee]

This patch series adds basic fastboot support for MediaTek MT8518 EMMC boards,
including musb-new structure for gadget driver and fastboot related configs.

---
Changes for v2:
   - Limit the config in this patch depends on ARCH_MEDIATEK.
   - config  all the added function,avoid affect other IC config.
   - fixed the build error for other defconfig,such as dra7xx_evm_defconfig.

mingming lee (6):
  usb: musb-new: mt85xx: add musb-new gadget driver.
  ARM: Mediatek: Add board_late_init to init usb gadget driver
  configs: mt8518: set global variables for fastboot
  configs: mt8518: enable usb gadget driver
  configs: mt8518: Enable fastboot related configs
  fastboot: mt85xx: add command to flash/erase emmc hwpart
