Add a local copy of the nord SoC and board device tree sources (nord.dtsi, nord-ride.dts, nord-rrd.dts, nord-embedded.dtsi and nord-gearvm.dtsi) along with the required clock and interconnect dt-bindings headers. Wire nord-ride.dtb into the build to enable early nord platform bring-up in U-Boot until the DTS files are available upstream. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
Add support for the nord Global Clock Controller (GCC). Implement the qcom,nord-gcc driver to provide clocks, resets and power domains required by nord peripherals. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
Add support for the nord NE Global Clock Controller (NEGCC). Implement the qcom,nord-negcc driver to provide clocks, resets and power domains required by nord peripherals during initialization. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
Add support for the nord SE Global Clock Controller (SEGCC). Implement the qcom,nord-segcc driver to provide clocks, resets and power domains required by nord peripherals during boot. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
Add support for the nord NW Global Clock Controller (NWGCC). Implement the qcom,nord-nwgcc driver to provide clocks, resets and power domains required by nord peripherals. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
Add support for the nord TCSR Clock Controller (TCSRCC). Implement the qcom,nord-tcsrcc driver to provide the clocks and resets required by nord platform peripherals. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
Enable the GCC, NEGCC, SEGCC, NWGCC and TCSRCC clock controller drivers in qcom_defconfig so support for the nord platform is built as part of the shared Qualcomm target configuration. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
Add a dedicated defconfig for the nord platform. Enable the drivers and board configuration options required to boot nord-based targets in U-Boot. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
Add support for the nord Top Level Mode Multiplexer (TLMM). Implement the qcom,nord-tlmm pinctrl driver to provide pin configuration support required by nord peripherals. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
Add nord-ride-u-boot.dtsi to describe the UFS PHY clocks and ufs_mem_phy node required by U-Boot's UFS driver. This allows the UFS controller to probe successfully on the nord-ride platform. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
…ate clocks on nord Several NEGCC/GCC gate clocks incorrectly used enable_mask = BIT(0) instead of their actual bit position in a shared multi-bit vote register. Fix enable_reg/enable_mask for 14 GCC and 2 NEGCC clocks to match the kernel driver. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
CONFIG_REMAKE_ELF's u-boot.elf link step used the toolchain's default page-size flags, and its .lds carried no 4K alignment padding, so TME's IMGAUTH rejected the image for misaligned segments. Add a REMAKE_ELF_LDSCRIPT default for ARCH_SNAPDRAGON pointing at a Snapdragon-specific .lds that pads .data to a 4K boundary, so this applies to any Snapdragon board using CONFIG_REMAKE_ELF, not just nord. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
CONFIG_REMAKE_ELF_LDSCRIPT alone leaves u-boot.elf linked with the toolchain's default page-size flags. Set LDFLAGS_u-boot-elf to the same 4K granule flags used for u-boot.bin, for any ARCH_SNAPDRAGON board, not just nord. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
ufs_mem_hc's phys property references ufs_mem_phy, but it is added disabled and nothing else enables it, so UFS never probes. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
…gion nord.dtsi's reserved-memory has no SMEM carveout, and nord has no qcom,smem node (the kernel doesn't need one here). U-Boot's SMEM driver needs both to locate the region, so add them mirroring EDK2's own SMEM reservation. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
nord's partition table references host IDs higher than the existing SMEM_HOST_COUNT=30, causing partition enumeration to fail with 'bad host'. Raise SMEM_HOST_COUNT to 256 and report the offending value when it is still too small. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
…gion cap configure_reserved_memory() passed raw reg values straight to mmu_change_region_attr_nobreak(), which works at 4K granularity and spins forever on sub-page regions (nord has 0x80-byte SCMI shmem mailboxes two-to-a-page). Page-align every region instead. Also raise N_RESERVED_REGIONS as nord's reserved-memory node has more entries than previously supported boards, and add a guard in set_regions() so an unmappable granule is reported instead of hanging. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
…entry
build_mem_map() only emitted entries for the reported DRAM banks,
leaving gaps between banks with no page-table entry at all. On
nord, firmware carves out sub-regions from the SMEM usable-RAM
table, leaving such gaps, and configure_reserved_memory() panics
if a DT reserved-memory node ever falls inside one ('PTE ... should
be a table').
Emit a separate MT_DEVICE_NGNRNE entry for each gap, matching the
attrs already used for the pre-DRAM peripheral block, plus
PTE_BLOCK_RO since nothing should ever legitimately write to an
unlisted, firmware-carved gap. This keeps gaps un-cacheable,
non-executable and read-only while still giving them a mapped,
splittable block entry. Any DT reserved-memory node that falls
inside a gap still gets its own explicit attrs from
configure_reserved_memory() (which overwrites the whole attrs mask,
RO bit included), so this only affects the parts of a gap with no
DT node. Bump rbx_mem_map[] so there's room for a gap entry between
every bank.

nord-gearvm.dtsi overrides qupv3_0/1/2, uart4, uart15 and ufs_mem_hc
to only the SoC-specific compatible strings, dropping the generic
qcom,geni-se-qup/geni-uart/geni-debug-uart/ufshc fallback that
upstream convention keeps as the last entry.
serial_msm_geni.c's geni_set_oversampling() checks for the generic
string directly rather than walking the whole compatible list, so
without the fallback no UART driver ever binds ('UART node must be
a child of geniqup node').

qcom_geni_fw_initialise() was unconditionally registered on EVT_LAST_STAGE_INIT for non-SPL builds. Add CONFIG_QCOM_GENI_FW_LOAD to make this optional, and disable it by default in qcom_defconfig for boards that don't need GENI firmware loading. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
Add the qcom,hwinfo U-Boot overlay node to nord-ride-u-boot.dtsi so that the qcom_hwinfo driver can read the IMEM boot cookie and the TCSR SOC_HW_VERSION register at boot. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
This reverts commit 5044572.
scsi_scan() removes existing SCSI block devices before rescanning, which can invalidate existing references and requires callers to avoid redundant scans. Add scsi_scan_new() to scan only controllers without bound block devices, making repeated scans safe and eliminating the need for scan guards at individual call sites. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
Capsule update may miss newly attached SCSI storage when SCSI has already been scanned earlier in boot. Use scsi_scan_new() to detect newly added devices while avoiding rescanning controllers that already have enumerated block devices. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
