rockchip: quartzpro64-rk3588: use DRAM banks from ATAGS
RK3588-based devices now support creating DRAM banks with proper holes
by reading the ATAGS from Rockchip TPL blob, so let's use that mechanism
instead.
Since ft_board_setup isn't defined anymore, there's no need for
selecting CONFIG_OF_BOARD_SETUP.
Similarly, because the quartzpro64-rk3588.c would be empty, it is simply
removed, with the (would-be-empty) Makefile as well.
The CONFIG_NR_DRAM_BANK now defaults to 10 which is a safe bet for
reading banks from ATAGS, so let's use the default value instead.

rockchip: NR_DRAM_BANKS now defaults to 10 when Rockchip TPL blob is used
When Rockchip TPL blob is used, the memory areas that can be used for
DRAM is gotten from ATAGS passed through the DRAM at a specific address.
The DDR_MEM tag contains at most 10 areas, so we should default to 10 if
Rockchip TPL blob is used. Note that it is technically possible we need
more if one of those 10 areas overlaps with reserved memory area,
forcing us to split it in two. But a default doesn't need to handle all
cases, only most.

rockchip: sdram: Support getting banks from TPL for rk3568 and rk3588
Allow RK3568 and RK3588 based boards to get the RAM bank configuration
from the ROCKCHIP_TPL stage instead of the current logic. This fixes
both an issue where 256MB of RAM is blocked for devices with >= 4GB
of RAM and where memory holes need to be defined for devices with
more than 16GB of RAM. In the event that neither SoC is used or the
ROCKCHIP_TPL stage is not used, fall back to existing logic.
The logic handles creating memory holes from reserved memory areas
defined in mem_map data struct in SoC C files, but only if the DRAM area
overlaps with one reserved memory area.
Since mem_map data struct is used, it should be rather straightforward
to add support for other SoCs if needed.
The logic is taken from Rockchip's U-Boot tag linux-5.10-gen-rkr4.1
(e08e32143dd).
Note that Rockchip's U-Boot/TF-A/OP-TEE modify the ATAGS at runtime as
well, but the DDR_MEM tag seems to be pretty much stable (though BL31
seems to be reserving only 1MB for itself at the moment).
u32 for ATAGS is used because it simplifies the pointer arithmetic and
it's expected that ATAGS are always below the 4GB limit allowed by u32.

rockchip: rock-pi-4-rk3399: enable booting from SPI flash
Some variants of the ROCK Pi 4 series have an SPI flash chip populated
which can be booted from. This patch enables support in U-Boot for
building the image for the SPI flash, support for booting U-Boot from the
SPI flash chip and support in U-Boot for accessing the SPI flash using
`sf` commands.
Not all variants (e.g. ROCK Pi 4B, ROCK 4 Model C Plus, ROCK 4SE) come
populated with an SPI flash chip, but have the footprint on the board so
a user could solder their own to the board. With this patchset applied,
these board variants without an SPI flash chip still boot from MMC.
I have enabled support for both Winbond and XTX SPI flash devices since
different hardware variants have different devices populated:
- `rockpi4_v13_sch_20181112.pdf` contains a Winbond part `W25Q64FWZPIG`
- `rockpi4_v14_sch_20210114.pdf` contains an XTX part `XT25F32BWOIGT`
The ROCK Pi 4 I have is marked as "ROCK PI 4 v1.48" and contains an SPI
flash chip from XTX:
=> sf probe
SF: Detected xt25f32 with page size 256 Bytes, erase size 4 KiB, total 4 MiB
In the interest of supporting all board variants and not regressing
existing users who boot from MMC, I have enabled support for booting from
both SPI flash chip variants in the defconfig and left the environment
storage location as MMC to not break existing users who have the
environment stored on MMC.

There's an external hardware pull-up strong enough to keep the STM32_RST

So fix it via selectively enabling LINUX_KERNEL_IMAGE_HEADER where it's
actually required.

pinctrl: qcom: ipq4019: support all pin functions
Currently, IPQ4019 pinctrl driver supports only a very limited number of
pin functions and is not fully DT compatible with Linux pinctrl nodes.
IPQ40xx SoC-s sometimes use different pin function numbers for the same
function depending on the pin number, so for example I2C0 on GPIO58 uses
function number 3 while on GPIO59 it uses function number 2.
So, in order to make the driver compatible with upstream DTS to avoid the
need to patch the pinctrl nodes in U-Boot and support all of the missing
pin functions lets rework the driver based on upstream Linux IPQ4019
pinctrl driver and the pending SM8150 U-Boot pinctrl driver which also uses
different function numbers pased on the exact pin number.

pinctrl: qcom: ipq4019: enable DM_FLAG_PRE_RELOC
If compiled with logging and debug UART support, the following is printed:
serial_msm serial@78af000: pinctrl_select_state_full: uclass_get_device_by_phandle_id: err=-19
This is due to the fact that IPQ4019 pinctrl driver is not available prior
to relocation and thus MSM serial will fail probing as pinctrl provider is
not available.
So, lets enable DM_FLAG_PRE_RELOC for IPQ4019 pinctrl to fix this.

pinctrl: qcom: allow selecting with ARCH_IPQ40XX
IPQ4019 pinctrl driver was moved to the dedicated Qualcomm pinctrl
directory, but the KConfig depends on ARCH_SNAPDRAGON only and thus
PINCTRL_QCOM_IPQ4019 cannot be selected when ARCH_IPQ40XX is used.

The driver currently requires the bit clock divider be hardcoded in
devicetree (or use the hardcoded default from apq8016).
The bit clock divider is used to derive the baud rate from the core
clock:
baudrate = clk_rate / csr_div
clk_rate is the actual programmed core clock rate which is returned by
clk_set_rate(), and this UART driver only supports a baudrate of 115200.
We can therefore determine the appropriate value for UARTDM_CSR by
iterating over the possible values and finding the one where the
equation above holds true for a baudrate of 115200.
Implement this logic and drop the non-standard DT bindings for this
driver.
Tested on dragonboard410c.

clk/qcom: ipq4019: return valid rate when setting UART clock
clk_set_rate() should return the clock rate that was set. The IPQ4019
clock driver doesn't set any rates yet but it should still return the
expected value so that drivers can work properly.
For a baud rate of 115200 with an expected bit clock divisor of 16, the
clock rate should be 1843200 so return that frequency.
clk/qcom: apq8016: return valid rate when setting UART clock
The clk_init_uart() helper always returns 0, but we're meant to return a
real clock rate. Given that we hardcode 115200 baud, just return the
clock rate that we set.

msm_serial_data structure does not have such property at all, so lets
remove it as otherwise it will fail compiling.
