70616df2bf Enable ROCKCHIP_SPL_BACK_TO_BROM for rock2 board
Rock2 has been tested with back to brom feature. The tricky part is that
with this feature the default environment is inside u-boot, and it's
defined for every rk3288 board independetly. So I just changed it for
rock2 here if ROCKCHIP_SPL_BACK_TO_BROM.

Solve by moving environment after u-boot before 1M boundary

4c043712e9 drivers: usb: xhci-fsl: Implement Erratum A-010151 for FSL USB3 controller
Currently the controller by default enables the Receive Detect feature in P3
mode in USB 3.0 PHY. However, USB 3.0 PHY does not reliably support receive
detection in P3 mode.
Enabling the USB3 controller to configure USB in P2 mode whenever the Receive
Detect feature is required.

f7c81e2879 apalis_t30: colibri_imx7: colibri_t30: fix ethernet functionality
Since commit aa7a648747
("net: Stop including NFS overhead in defragment max") the following
has been reproducibly observed while trying to transfer data over TFTP:

Load address: 0x80408000
Loading: EHCI timed out on TD - token=0x8008d80
T EHCI timed out on TD - token=0x88008d80

ee562dc34e ARM: tegra: pull Tegra210 SoC DT from Linux v4.7
The primary benefit of this change is that it adds all missing clocks and
resets properties to peripherals. This will allow peripheral drivers to
migrate to the standard clock and reset APIs in the future.

Main changes:
* Brought in the correct Tegra210 CAR binding; the old file in U-Boot
  appears to be a renamed version of the Tegra124 bindings rather than
  the real Tegra210 version.
* Conversion of SPI and UART nodes to standard DMA bindings. U-Boot
  doesn't use DMA so isn't affected.
* Split of EHCI and USB PHY nodes. The EHCI nodes continue to contain all
  information required by U-Boot, so U-Boot is not affected.
* Conversion of many magic numbers to named defines.
* Addition of many nodes not used by U-Boot, including separation of the
  Tegra LIC (Legacy IRQ controller) and GIC.
* Node sort order fixes.

Remaining deltas relative to the Linux DT:
* U-Boot has enabled PCIe for Tegra210, but the kernel hasn't yet.
* The GPIO node compatible value in the kernel explicitly includes
  Tegra124 values whereas U-Boot does not. I'll send a kernel patch to
  correct this.

3b8c1b3b22 ARM: tegra: pull Tegra124 SoC DT from Linux v4.7
The primary benefit of this change is that it adds all missing clocks and
resets properties to peripherals. This will allow peripheral drivers to
migrate to the standard clock and reset APIs in the future.

Main changes:
* USB phy_type property is aligned with the kernel, so board files are
  updated so the final DT content doesn't change. I'm not convinved that
  Nyan uses HSIC phy_type. However, I'd rather this change be a no-op,
  and any DT bug-fixes be separate.
* Sync misc changes from the kernel: missing DT content, minor compatible
  value fixes, typos.

Remaining deltas relative to the Linux DT:
* U-Boot uses #address-cells/#size-cells of 1 whereas the kernel uses 2.
  I believe U-Boot's DT parsing currently assumes that these values match
  the physical address size, so I didn't synchronize this part of the DT.
* U-Boot uses the original XUSB PHY DT binding, wherease the kernel DT
  has moved to a newer version. Thus, XUSB client nodes include properties
  names phys and phy-names that do not appear in the kernel, and don't
  include pad definitions in the padctl node.

* Addition of many nodes not used by U-Boot.
* Node sort order fixes.

  whereas the kernel does not. I'll send a kernel patch to correct this.

ce2f2d2ae7 ARM: tegra: pull Tegra30 SoC DT from Linux v4.7
The primary benefit of this change is that it adds all missing clocks and
resets properties to peripherals. This will allow peripheral drivers to
migrate to the standard clock and reset APIs in the future.

Main changes:
* Modification of PCIe memory region addresses. The HW memory layout is
  programmable, so this should work fine, and Beaver PCIe was tested
  without issue.
* Removal of pcie_xclk from the PCIe node and clock binding header. This
  clock doesn't exist and isn't used; only a reset with this ID exists.
* Conversion of SPI nodes to standard DMA bindings. U-Boot doesn't use
  DMA so isn't affected.
* Split of EHCI and USB PHY nodes. The EHCI nodes continue to contain all
  information required by U-Boot, so U-Boot is not affected.
* Changed the phy_type value for the second USB port. This required board
  DTs to be updated to keep the same configuration.
* Boards need to define the clk32k_in clock that feeds the Tegra PMC.
* Addition of tegra30-mc.h since tegra30.dtsi now includes it.
* Conversion of many magic numbers to named defines.
* Addition of many nodes not used by U-Boot.
* Node sort order fixes.

Remaining deltas relative to the Linux DT:
* None.

64a4fe7401 ARM: tegra: increase console buffer size and sys args num
The Linux-for-Tegra kernel uses a very long command line.

The default value of CONFIG_SYS_CBSIZE is too small to printf out the
long command line and causes a message like:
  bootarg overflow 602+0+0+1 > 512
on the console, and the board refuses to boot.

The default value of CONFIG_SYS_MAXARGS is too small to add a long
long command line, and the kernel won't boot without the complete
bootargs.

Increasing these two config options solves this problem.

5e61b0df41 ti_armv7_common.h: Adjust malloc pool size in all cases.
Previously we had been adjusting CONFIG_SYS_MALLOC_LEN based on if
CONFIG_DFU_MMC has been set or not.  However, for quite some time this
has not been the case as we often include <configs/ti_armv7_common.h>
prior to setting CONFIG_DFU_MMC so we would always use 16MiB and then
not have enough room for to DFU files.  Given the amount of memory we
always have, setting a minimum size of 32MiB for malloc is reasonable.
However, in the SPL case not only do we not need that much we start
running into overlap problems and then will fail to boot.  Since we
don't need 16MiB in the SPL case, bring this down to 8MiB.

4815db87f5 reset: add no-op stubs for optional reset control
My motivation for this patch is to make reset control handling
optional for generic drivers.

I want to add reset control to drivers/usb/host/ehci-generic.c,
but it is used by several platforms, some will implement a reset
controller driver, some will not.

Add no-op stubs in order to avoid link error for drivers that
implement reset controlling, but still it is optional.

10a7a1b8ba ext4: Avoid corruption of directories with hash tree indexes
