[U-Boot] [PATCH v3 0/4] rockchip: rk3288: add fastboot support

[Ziyuan Xu]

This patchset add the fastboot support for rk3288, and I have tested on
firefly-rk3288 board.

Fix an issue which was mentioned in V1's cover-letter:
The DMA buffer was always zero after DMA transfer is complete, It takes
no effect that invalidate dcache after the DMA is complete and before
the CPU reads it. It's important to invalidate dcache before starting
DMA, ensure coherency and prevent from any dirty lines in the cache
which from the DMA buffer.

Summary of changes in this series:
- Achieve UOC_CON_OFFSET physical address from DT
- Make UOC_CON registers to be unfixed which should be got from DT
- Add new commit dd77b11fd44a84 (usb: dwc2: Invalidate dcache before
staring DMA)

Changes in v3:
- Make UOC_CON registers to be unfixed which should be got from DT
- Achieve UOC_CON_OFFSET physical address from DT
- New commit since v3 to fix the coherence issue between memory and
cache

Changes in v2:
- Rename rk3288_usb_phy.c to rockchip_usb_syno_phy.c
- Rework the behaviour in otg_phy_init() and otg_phy_off()
- Update detailed commit message
- Modify the macro's values
- Achieve the regs_phy from DT
- Update comments a little
