3b10e6eb68 sun6i: Add new p2wi controller driver
The A31 uses a new push-pull two wire interface, which features higher
transfer speeds (upto 6 MHz) in theory. While the hardware can burst 8
bytes each time, this driver will only see very little use and thus is
limited to single byte transmission only.

f2863ff3f4 arm: imx: make bmode command work with SPL/U-Boot combo
The bmode command forces the SoC to use a specific boot device
by writing its boot mode into SRC_GPR9, and notifying the SoC of
the change using SRC_GPR10[28] bit: if the bit is on, bootROM
uses the value in SRC_GPR9 instead of SRC_SMBR1 to determine
the boot device.

SPL on the other hand is oblivious to this distinction, so once
the bootROM loads SPL from the device configured in SRC_GPR10,
SPL will attempt to load U-Boot from the device configured in
SRC_SMBR1, which is not updated by the bootROM to the value in
SRC_GPR9.

The result is that the selected boot device is not used across all
the boot stages.

Update spl_boot_device() to look at gpr9 when necessary.

25026fa9f1 ARM: cache-cp15: Use more accurate types
size_t is the canonical type to represent variables that contain a size.
Use it instead of signed integer. Physical addresses can be larger than
32-bit, so use a more appropriate type for them as well. phys_addr_t is
a type that is 32-bit on systems that use 32-bit addresses and 64-bit if
the system is 64-bit or uses a form of physical address extension to use
a larger address space on 32-bit systems. Using these types the same API
can be implemented on a wider range of systems.

0d8c7f747e ARM: UniPhier: decrease pre-reloc malloc area size
In the current implementation of the boot sequence of UniPhier
platform, 32KB temporary RAM is available before relocation.
The malloc area and the stack shares the 32KB area.

With CONFIG_SYS_MALLOC_F_LEN set to 0x7000 (28KB), only 0x1000 (4KB)
is left for the stack.  In some use cases, the system hangs up
with stack over-flow.

Even with driver-model UART enabled, the malloc area of 0x2000 (8KB)
should be enough.

that IIC_CNTL_RPST is set on that part of the transfer that should
begin with a repeated start. But repeated start is about not sending a
stop condition, so IIC_CNTL_RPST has to be set on the last transfer
before the repeated start happens.
