The STM32_RST line is routed to the ATtiny microcontroller
PA0/RESET/UPDI pin. By driving the PX30 SoC pin as GPIO output high, we
prevent external UPDI to be used for flashing without first putting this
pin as GPIO input, an extra step we could avoid in userspace.
There's an external hardware pull-up strong enough to keep the STM32_RST
state high on ATtiny side but weak enough it can be overridden by
external UPDI. This also means it is safe to use for the STM32 variant,
where STM32_RST line will be in the same state as if output high was
used.
The Q7 standard specifies that MFG_NC1 and MFG_NC2 (used for UPDI for
Ringneck) pins should neither be driven by the carrierboard, nor have
pull-up or pull-down resistors. This means this commit is safe to use
regardless of the carrierboard this module would be connected to
(provided it follows the Q7 standard).

Rockchip BROM writes a boot source id at CFG_IRAM_BASE + 0x10, this id
indicates from what storage media TPL/SPL was loaded from.
SPL uses this id to determine what device "same-as-spl" represent when
determining from where FIT should be loaded. This works as long as the
boot_devices array contain a matching id <-> node path entry.
However, SPL typically load a small part of TF-A into SRAM and on RK3399
this overwrites the CFG_IRAM_BASE + 0x10 addr used for boot source id.
For affected devices the u-boot,spl-boot-device would not be set when
booting from SPI flash and the flash@0 node was not explicitly listed
in the u-boot,spl-boot-order prop.
Here boot source id is 3 before FIT images is loaded, and 0 after:

Currently fetching files bigger that cause a data transfer greater than
U16_MAX fails.
The reason is that the specification defines the datalength register
as a 16 bit wide register, but in u-boot it is used as if it is an
32 bit register. Therefore values greater than U16_MAX cause an
infinite loop inside u-boot. U-boot expects to get more data from
interface/hardware then it will ever get and therefore inifintely waits

Some arm64 platforms may include SDIO host controllers that
only support 32-bit ADMA. While the Linux kernel detects which
size is supported and adjusts the descriptor size used dynamically,
the previous u-boot implementation statically selected between the
two depending on whether DMA_ADDR_T_64BIT was defined. Because the
static selection is already in place and effective for most platforms,
this patch logically separates "64 bit addresses are used for DMA on
this platform" and "64 bit addresses are used by the SDIO host
controller for ADMA" in order to support the small number of platforms
where these statements are not equivalent.
Using 32 bits is opt-in and existing 64 bit platforms should be
unaffected by this change.

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.
