normal (not weak).
* The function board_usb_init in drivers/usb/host/xhci-omap.c calls to

This commit adds support for DM I2C on sunxi platform. It can coexist
with old style sunxi I2C driver, because it is still used in SPL and
by some SoCs.
Because sunxi platform doesn't yet support DM clk, reset and pinctrl
driver, workaround is needed to enable clocks and set resets and
pinctrls. This is done by calling i2c_init_board() in board_init().
This means that CONFIG_I2Cx_ENABLE options needs to be correctly set
in order to use needed I2C controller.

Video driver for older Allwinner SoCs uses cfb console framework which
in turn uses struct ctfb_res_modes to hold timing informations. However,
DM video framework uses different structure - struct display_timing.
It makes more sense to convert lcdc to use new timing structure because
all new drivers should use DM video framework and older drivers might be
rewritten to use new framework too.

If the system is running PSCI firmware, the System Reset function
(func ID: 0x80000009) is supposed to be handled by PSCI, that is,
the SoC/board specific reset implementation should be moved to PSCI.
U-Boot should call the PSCI service according to the arm-smccc
manner.
The arm-smccc is supported on ARMv7 or later. Especially, ARMv8
generation SoCs are likely to run ARM Trusted Firmware BL31. In
this case, U-Boot is a non-secure world boot loader, so it should
not be able to reset the system directly.
