The memory map for the RZ/G2L family differs from that of previous R-Car
Gen3/Gen4 SoCs.
A high level memory map can be seen in figure 5.2 (section 5.2.1) of the
RZ/G2L data sheet rev 1.30 published May 12, 2023. A summary is included
here (note that this is a 34-bit address space):
* 0x0_0000_0000 - 0x0_0002_FFFF SRAM area
* 0x0_0003_0000 - 0x0_0FFF_FFFF Reserved area
* 0x0_1000_0000 - 0x0_1FFF_FFFF I/O register area
* 0x0_2000_0000 - 0x0_2FFF_FFFF SPI Multi area
* 0x0_3000_0000 - 0x0_3FFF_FFFF Reserved area
* 0x0_4000_0000 - 0x1_3FFF_FFFF DDR area (4 GiB)
* 0x1_4000_0000 - 0x3_FFFF_FFFF Reserved area
Within the DDR area, the first 128 MiB are reserved by TrustedFirmware.
The region from 0x43F00000 to 0x47DFFFFF inclusive is protected for use
in TrustedFirmware/OP-TEE, but all other memory is included in the
memory map. This reservation is the same as used in R-Car
Gen3/Gen4 and RZ/G2{H,M,N,E} SoCs.
DRAM information is initialised based on the data in the fdt.

The ARM TrustedFirmware code for the Renesas RZ/G2L SoC family passes a
devicetree blob to the bootloader as an argument in the same was
previous R-Car Gen3/Gen4 SoCs. This blob contains a compatible string
which can be used to identify the particular SoC we are running on.
We do this as reading the DEVID & PRR registers from u-boot is not
sufficient to differentiate between the R9A07G044L (RZ/G2L) and
R9A07G044C (RZ/G2LC) SoCs. An additional read from offset 0x11861178 is
needed but this address is in the OTP region which can only be read from
the secure world (i.e. TrustedFirmware). So we have to rely on
TrustedFirmware to determine the SoC and pass this information to u-boot
via an fdt blob.

This driver adds support for the gpio features of the GPIO/PFC module in

the `rzg2l-pfc-pinctrl` driver as the same hardware block provides both
GPIO and pin multiplexing features.

A multi-function `rzg2l-pfc` driver is defined for UCLASS_NOP, which
binds the `rzg2l-pfc-pinctrl` UCLASS_PINCTRL driver dynamically. We also
define common macros and functions for the PFC in <renesas/rzg2l-pfc.h>.
This makes it easy to add an additional UCLASS_GPIO driver for the GPIO
functionality of this module in a follow-up patch.

On the Renesas RZ/G2L SoC family, valid GPIO numbers are not contiguous.
This is determined by the device tree, where a fixed number of bits are
used for the 'pin' number within a 'port', even though not all ports
have the same number of pins. The device tree can't be changed here
without breaking backwards compatibility in Linux, which we don't want
to do.
To avoid printing a status for each of these invalid GPIO numbers when
a user executes `gpio status -a`, we allow gpio_get_function() to return
-ENOENT when the given offset does not refer to a valid GPIO pin and we
skip printing anything if this occurs.

This driver provides clock and reset control for the Renesas R9A07G044L
(RZ/G2L) and R9A07G044C (RZ/G2LC) SoC. It consists of two parts:
* driver code which is applicable to all SoCs in the RZ/G2L family.
* static data describing the clocks and resets which are specific to the
R9A07G044{L,C} SoCs. The identifier r9a07g044 (without a final letter)
is used to indicate that both SoCs are supported.
clk_set_rate() and clk_get_rate() are implemented only for the clocks
that are actually used in u-boot.
The CPG driver is marked with DM_FLAG_PRE_RELOC to ensure that its bind
function is called before the SCIF (serial port) driver is probed. This
is required so that we can de-assert the relevant reset signal during
the serial driver probe function.
