475bb949ed rockchip: Fix u-boot-rockchip.bin build
Currently there are a few arm32 rockchip board configs that don't
generate u-boot-rockchip.bin when running make because CONFIG_BINMAN
is not enabled. This patch changes CONFIG_ARCH_ROCKCHIP to also select
CONFIG_BINMAN if CONFIG_SPL and !CONFIG_ARM64.

Example builds that don't generate u-boot-rockchip.bin without this
patch:

export ARCH=arm
export CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf-
make kylin-rk3036_defconfig
make

export ARCH=arm
export CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf-
make rock_defconfig
make

export ARCH=arm
export CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf-
make tinker-rk3288_defconfig
make

be5c0608b8 usb: Enforce DM_USB migration for USB_HOST devices.
As the deadline for migration to DM_USB, when using a USB host
controller has now gone two years past the deadline, enforce migration.
This is done by:

- Ensuring that all host controller options (other than the very legacy
  old MUSB ones) now select USB_HOST.  USB_HOST now enforces DM_USB and
  OF_CONTROL.
  - Remove other parts of Kconfig logic that had platforms pick DM_USB.
  - To keep Kconfig happy, have some select statements test for USB_HOST
    as well.
- Re-order some Kconfig entries and menus so that we can cleanly pick
  host or gadget roles.  For the various HCD options that have platform
  glue options, group them together and update dependencies in some
  cases.
- As SPL_DM_USB is not required, on platforms that had not yet enabled
  it, disable it.

1238d0143a arm: highbank: Do DRAM init from DT
So far U-Boot was hard coding a (surely sufficient) memory size of 512
MB, even though all machines out there have at least 4GB of DRAM.
Since U-Boot uses its memory knowledge to populate the EFI memory map,
we are missing out here, at best losing everything beyond 4GB on Midway
boxes (which typically come with 8GB of DRAM).

Since the management processor populated the DT memory node already with
the detected DRAM size and configuration, we use that to populate
U-Boot's memory bank information, which is the base for the UEFI memory
map.
This finally allows us to get rid of the NR_DRAM_BANKS=0 hack, that we
had in place to avoid U-Boot messing up the DT memory node before
loading the kernel.

Also, to cover the whole of memory, we need to enable PHYS_64BIT.

debb07bf10 net: calxedagmac: Convert to DM_ETH
To squash that nasty warning message and make better use of the newly
gained OF_CONTROL feature, let's convert the calxedagmac driver to the
"new" driver model.
The conversion is pretty straight forward, mostly just adjusting the
use of the involved data structures.
The only actual change is the required split of the receive routine into
a receive and free_pkt part.
Also this allows us to get rid of the hardcoded platform information and
explicit init calls.

This also uses the opportunity to wrap the code decoding the MMIO
register base address, to make it safe for using PHYS_64BIT later.

109552d773 arm: highbank: Enable OF_CONTROL
All Calxeda machines are actually a poster book example of device tree
usage: the DT is loaded from flash by the management processor into
DRAM, the memory node is populated with the detected DRAM size and this
DT is then handed over to the kernel.
So it's a shame that U-Boot didn't participate in this chain, but
fortunately this is easy to fix:

Define CONFIG_OF_CONTROL and CONFIG_OF_BOARD, and provide a trivial
function to tell U-Boot about the (fixed) location of the DTB in DRAM.
Then enable DM_SERIAL, to let the PL011 driver pick up the UART platform
data from the DT. Also define AHCI, to bring this driver into the driver
model world as well.

 - 2 x SGMII ETH for management communication via back-plane
 - 1 x uQE HDLC for management communication via back-plane
 - 1 x I2C for peripheral devices
 - 1 x SPI for peripheral devices
 - 1 x UART for debug logging

It is foreseen that the design will be later re-used for another XMC and

f5cb6c3081 qemu-arm64: Enable POSITION_INDEPENDENT
Now that PIE works when U-Boot is started from ROM, let's enable
CONFIG_POSITION_INDEPENDENT, which allows to load U-Boot also via
ARM Trusted-Firmware's fip.bin to DRAM, without tweaking the
configuration.

To get a writable initial stack, we need to keep the fixed initial
stack pointer, which points to DRAM in our case.
