Subject: [PATCH] scsi: ufs: qcom: defer probe before the device supplies are
 on

ufshcd_pltfrm_init() enables vcc and vccq in ufshcd_hba_init() before
ufs_qcom_init() looks up the PHY and the interconnect paths. When one of
them defers, the error path disables the supplies and drops their load
votes under a UFS device the bootloader left running.

# Put an Alpaca (EPM) driven QRD into EDL the way Qualcomm's test automation
# controller does (bootToEDL in configurations/TAC_PSOC_44.tcnf, legacy
# command table in TACPSOCLegacyCommands.cpp), and report every USB device
# the board brings up, so a missing serial or an unexpected port shows.
#
# Run on the cdba host with cdba-server NOT holding the Alpaca tty.
# Usage: alpaca-edl-check.sh <alpaca tty> <edl serial> [tries]
#   e.g. alpaca-edl-check.sh /dev/serial/by-id/usb-QUALCOMM_Inc._Embedded_Power_Measurement__EPM__device_6E02020C040C1F14-if01 AAFD8CDA 3
# CONTROL=1 runs the same sequence without the EDL bit (expect no 9008).

Subject: [PATCH 1/8] arm64: dts: qcom: glymur: reserve the TZ carve-outs

The secure world on Glymur owns the DDR from 0xd7019000 to 0xd9dc0000:
the XBL_SC region, a reserved region, the TZ (QTEE) image and heap, the
trusted application region and the DRAM tag area. None of it is
described in glymur.dtsi. With the stock UEFI this goes unnoticed because
UEFI leaves the range out of the memory map it hands to the OS, but a
