Change ADMA_TABLE_NO_ENTRIES to round the division up to fully
contain CONFIG_SYS_MMC_MAX_BLK_COUNT, fixing potential buffer overflow
of the ADMA descriptor table.
sdhci_prepare_adma_table() expecitily states it does _not_ check for
overflow as the descriptor table size is dependent on
CONFIG_SYS_MMC_MAX_BLK_COUNT. However, the ADMA_TABLE_NO_ENTRIES
calculation does not round up the divison, so with the current u-boot
defaults:
max_mmc_transfer = (CONFIG_SYS_MMC_MAX_BLK_COUNT * MMC_MAX_BLOCK_LEN) =
65535 * 512 = 33553920 bytes.
ADMA_TABLE_NO_ENTRIES = max_mmc_transfer / ADMA_MAX_LEN =
33553920 / 65532, which does not divide cleanly.
actual_max_transfer = ADMA_TABLE_NO_ENTRIES * ADMA_MAX_LEN = 512 *
65532 = 33552384, which is smaller than max_mmc_transfer.
This can cause sdhci_prepare_adma_table() to write one extra
descriptor, overflowing the table when a transaction larger than
actual_max_transfer is issued.

Add this hook so that it can be overridden with driver specific
implementations. We also let the original sdhci_adma_write_desc()
accept &desc so that the function can set its new value. Then export
the function so that it could be reused by driver's specific
implementations.
The above is a port of Linux kernel commit 54552e4948cbf
In addition, allow drivers to allocate their own ADMA descriptor
tables if additional space is required.
Finally, fix the assignment of adma_addr to fix compiler warning
on 64-bit platforms that still use 32-bit DMA addressing.

- move to OF_UPSTREAM for sl28

Support is added for 5 new Qualcomm SoCs:
* QCM2290 and SM6115 are low and mid range SoCs used on the RB1 and RB2
respectively. SM6115 is also used in some mid-range smartphones/tablets.
Initial support includes buttons and USB (host and gadget).
* SM8250 is a flagship SoC from 2020 used on the RB5, as well as many flagship
smartphones. The board can boot to a U-Boot prompt, but is missing regulators
necessary for USB support.
* SM8550, and SM8650 are flagship mobile SoCs from 2023 and 2024
respectively. Found on many high end smartphones.
In addition:
* Support is added for the Schneider HMIBSC board.
* mach-snapdragon switches to OF_UPSTREAM
* IPQ40xx gets several regressions fixed and some overall cleanup.
* The MSM serial driver gains the ability to generate the bit-clock
automatically, no longer relying on a custom DT property.
* The Qualcomm SMMU driver gets a generic compatible (so per-SoC compatibles
don't need to be added).
* Support for the GENI I2C controller is added.
* The qcom SPMI driver has SPMI v5 support fixed, and v7 support added.
* The qcom sdhci driver gets some fixes for SDCC v5 support.
* SDM845 gains sdcard support
* Support is added for the Synopsys eUSB2 PHY driver (used on SM8550 and SM8650)
* SYS_INIT_SP_BSS_OFFSET is set to 1.5M to give us more space for FDTs.
* RB2 gets a work-around to fix the USB dr_mode property before booting Linux.

Use the new device devicetree files in dts/upstream/ and delete the old
ones. Still keep the -u-boot.dtsi with all u-boot specifics around.
There is one catch and that is fsl-ls1028a-kontron-sl28-var3.dts which
is not available upstream (yet!). For now, the base dts is used for this
variant as this only differ in the compatible and the (human readable)

Add Support for the Qualcomm Generic Interface (GENI) I2C interface
found on newer Qualcomm SoCs.
The Generic Interface (GENI) is a firmware based Qualcomm Universal
Peripherals (QUP) Serial Engine (SE) Wrapper which can support multiple
bus protocols depending on the firmware type loaded at early boot time
based on system configuration.
It also supports the "I2C Master Hub" which is a single function Wrapper
that only FIFO mode I2C.
It replaces the fixed-function QUP Wrapper found on older SoCs.
The geni-se.h containing the generic GENI Serial Engine registers defines
is imported from Linux.
Only FIFO mode is implemented, neither SE DMA nor GPI DMA are implemented.

Some Qualcomm boards have only one USB controller which is muxed between
the type-c port and an internal USB hub for type-A and ethernet. We
modify the DT for these to force them to host mode in U-Boot. However in
Linux DRD role switching is supported (required, even). Use

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.

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.

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_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.
