Add the "qcom,hwinfo" DT node with the appropriate IMEM boot-cookie and TCSR HW-version offsets for each board, enabling FIT multi-DTB selection (CONFIG_QCOM_FIT_MULTIDTB) to detect hardware parameters at boot time. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>
Add a U-Boot device tree overlay for shikra-cqs-evk carrying a "reboot-mode" subnode under the psci node, declaring "mode-edl" so that "reset -edl" enters Qualcomm EDL/download mode via a PSCI SYSTEM_RESET2 vendor reset. The magic value <0x80000000 0x00000001> is reset_type = 0x80000000 (vendor bit set) with a cookie of 1. Signed-off-by: Aswin Murugan <aswin.murugan@oss.qualcomm.com>

The qcom,hwinfo DT node is already present in
shikra-cqs-evk-u-boot.dtsi [1] and is used by FIT multi-DTB selection
(CONFIG_QCOM_FIT_MULTIDTB) to detect hardware parameters at boot
time. Add the same node with the required IMEM boot-cookie and
TCSR HW-version offsets to shikra-iqs-evk-u-boot.dtsi.
Similarly reboot mode node is used for reset -edl support
