Commit 906ee6785b ("mmc: sd: Handle UHS-I voltage signaling without
power cycle") added detection of cards already operating at 1.8V
signaling via mmc_sd_card_using_v18(). This correctly handles the
warm-reboot scenario in mmc_startup().
However, mmc_deinit() strips ALL UHS capabilities from the card caps
and calls sd_select_mode_and_width() to downgrade the card before
kernel handoff. For a card that has switched to 1.8V, uhs_en is
already true (via OCR_S18R in mmc->ocr), so sd_select_mode_and_width()
attempts UHS mode selection -- but no UHS modes remain in the filtered
caps. The non-UHS fallbacks (SD_HS, MMC_LEGACY) are 3.3V speed modes
which, when selected while signaling at 1.8V, leave the card in an
inconsistent state it cannot recover from without a power cycle.
Per SD Physical Layer Specification: "Once the card enters 1.8V
signaling mode, the card cannot be switched to 3.3V signaling without
power cycle. If the card receives CMD0, card returns to Idle state but
still works with SDR12 timing."
Fix by using a UHS capability mask that preserves UHS_SDR12 when the
card is operating at 1.8V. SDR12 is the minimum valid UHS-I mode and
is always available at 1.8V signaling per the SD specification, so the
card is left in a consistent (1.8V) state at a low, safe speed.
Fixes: 906ee6785b ("mmc: sd: Handle UHS-I voltage signaling without power cycle")

mmc_bwrite() uses mmc->cfg->b_max directly to limit per-transfer block
count. The read path (mmc_bread()) correctly calls mmc_get_b_max()
which dispatches to the host driver get_b_max() callback. This callback
allows host drivers to enforce DMA boundary constraints based on the
buffer address.
Fix mmc_bwrite() to use mmc_get_b_max() to match the read path. This
requires removing the static qualifier from the non-DM mmc_get_b_max()
and adding its declaration to mmc_private.h.

sdhci_init() allocates a 512KB aligned bounce buffer for controllers
with SDHCI_QUIRK_32BIT_DMA_ADDR. In the non-DM code path, sdhci_init()
is registered as ops->init and called on every mmc_init(). Each call
allocates a new buffer without checking or freeing the previous one,
leaking 512KB per re-initialization.
Fix by guarding the allocation with !host->align_buffer so it only
allocates on the first call.

In rpmb_route_frames(), the RPMB_REQ_READ_DATA case checks
"req_cnt != 1 || !req_cnt" which is tautological -- !req_cnt (req_cnt
== 0) is always a subset of req_cnt != 1. The second operand is dead
code.
Based on the pattern of all other cases in the switch (RPMB_REQ_KEY,
RPMB_REQ_WRITE_DATA, RPMB_REQ_WCOUNTER) which validate rsp_cnt, this
was meant to be "req_cnt != 1 || !rsp_cnt". Without this fix, a caller
could pass rsp_cnt=0 for a read request without validation.

mmc_poll_for_busy() returns a false -ETIMEDOUT if the card becomes
ready on the exact iteration where timeout_ms reaches 0. The card-ready
check breaks out of the loop, but then the post-loop check
"if (timeout_ms <= 0)" fires and returns -ETIMEDOUT despite the card
being ready.
Fix by returning 0 directly when the card is ready instead of breaking
out of the loop. The only exit from the loop is now the timeout path,
so the post-loop code unconditionally returns -ETIMEDOUT.

The read_poll_timeout() macro breaks out of its loop when the condition
evaluates to true. The current code uses "!tx_complete" as the
condition, which means it exits immediately when tx_complete is false
(i.e., transmission has NOT completed yet), rather than waiting for
completion.
Fix the condition to "tx_complete" so that the poll loop waits until
the TCPC signals transmission success/failure/discard before
proceeding.
Without this fix, tcpm_pd_transmit() returns before the TCPC has
finished transmitting, causing the PD state machine to proceed with
stale tx_status values.

Use dev_read_addr_index_ptr() which supports both live device tree and
flat DT backends, avoiding direct dependency on devfdt_* helpers.

Use dev_remap_addr() to simplify code.
dev_remap_addr() does same thing as dev_read_addr() + map_physmem(). And
it supports both live device tree and flat DT backends, avoiding direct
dependency on devfdt_* helpers.

Replace legacy FDT parsing in get_reg() with the device API
dev_read_phandle_with_args() which removes direct access to gd->fdt_blob
and aligns the driver with modern U-Boot DT handling.
The offset is retrieved from the phandle argument instead of manually
parsing the property cells. Add validation for the argument
count to avoid out-of-bounds access on malformed DTs.
Also switch from devfdt_get_addr_size_index() to dev_read_addr_size_index()
for consistency with the DM API.
No functional changes.

scripts/Makefile.lib already handles the including path for imx8mq.dtsi
from dts/upstream. No need to keep a copy in arch/arm/dts/, and there
is very minimal changes compared with the one in dts/upstream, so remove
the copy.

The RDB doesn't support NAND boot at all, remove the config for it.
Apparently, it was introduced by commit dd84058d24 ("kconfig: add
board Kconfig and defconfig files") which ran some scripts. Maybe that
script was wrong or the source boards.cfg was wrong. In any case, there
is no NAND flash on the RDB.
