57fe5c64cb riscv: Add indirect stringification to csr_xxx ops
With current csr_xxx ops, we cannot pass a macro to parameter
'csr', hence we need add another level to allow the parameter
to be a macro itself, aka indirect stringification.

60262cd041 timer: Add generic driver for RISC-V privileged architecture defined timer
RISC-V privileged architecture v1.10 defines a real-time counter,
exposed as a memory-mapped machine-mode register - mtime. mtime must
run at constant frequency, and the platform must provide a mechanism
for determining the timebase of mtime. The mtime register has a
64-bit precision on all RV32, RV64, and RV128 systems.

Different platform may have different implementation of the mtime
block hence an API riscv_get_time() is required by this driver for
platform codes to hide such implementation details. For example,
on some platforms mtime is provided by the CLINT module, while on
some other platforms a simple 'rdtime' can be used to get the timer
counter.

With this timer driver the U-Boot timer functionalities like delay
works correctly now.

655c6d997d poplar: fix boot failure caused by serial driver change
Commit 4687919684 ("serial: Remove DM_FLAG_PRE_RELOC flag in various
drivers") essentially drops flag DM_FLAG_PRE_RELOC from serial_pl01x
driver for Poplar platform, because the platform falls into the
following strategy category made by the commit.

  Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for
  drivers that support both statically declared devices and
  configuration from device tree

Before the commit lands, Poplar platform works by statically declaring
pl011 serial device via U_BOOT_DEVICE() with DM_FLAG_PRE_RELOC flag set
in the driver.  But since Poplar also supports device configuration from
device tree, the commit practically drops the flag for Poplar, and hence
breaks the platform from booting.

This patch changes platform code and device tree to initiate pl011
serial device from device tree rather than static declaration, so that
above strategy about DM_FLAG_PRE_RELOC applies to Poplar, and therefore
the reported boot failure gets fixed.

5d060ec0dc configs: am335x_boneblack_vboot: enable DM_USB and RNDIS boot in SPl
Enable DM_USB and DM_USB_GADGET for this platform. Also enable RNDIS boot
support (SPL load u-boot over USB RNDIS).
This is an example of how to use DM_USB on a am335x-based board.
A subsequent series will take this a step further and modify more
defconfigs.

7a43dd7aa6 arm: am33xx: Register USB controllers if DM_USB is used but not OF_CONTROL
When DM_USB is used, either the USB controllers are bound when the DTB
is parsed (when OF_CONTROL is enabled) or they are bound using the
U_BOOT_DEVICES() macro.
In the later case, the platform data is passed in a struct ti_musb_platdata
because it cannot be read from the DTB.

7d98dbcc3d usb: musb-new: Add support for DM_USB
Enable DM for USB peripheral in the musb-new driver.
Also make sure that the driver can be used in the SPL.
This implies that:
* the driver must work with and without the OF_CONTROL option. That
in turn, implies that the platform data can be passed in a struct
ti_musb_platdata or be read from the dtb
* usb.o is linked in the SPL if host support is enabled

Another change is that the driver does not fail to bind (and stop the boot
process) if one of the child driver does not bind. Reporting the error is
enough. This kind of error would appear if the port is configured in the
DTS but the driver is not activated in the config.

1594c75b3e usb: musb-new: Allow the diver not to use the set_phy_power() callback
The set_phy_power() callback is part of struct omap_musb_board_data. This
structure is part of the platform data passed to the musb-new driver. This
does not really fit with the Driver Model, so allow not to use struct
omap_musb_board_data to turn the phy on or off.
