# Board configuration file for the Freescale IMX6Q Sabre SD EVM
#
# This board does not have an embedded JTAG adapter, you must source
# a suitable adapter configuration before sourcing this file.
# Sabre SD has a standard ARM-20 JTAG connector with
# nTRST and nSRST available.
reset_config trst_and_srst
# the only possible transport is JTAG
transport select jtag
# iMX6Q POR gates JTAG and the chip is completely incommunicado
# over JTAG for at least 10ms after nSRST is deasserted
adapter_nsrst_delay 11
# Source generic iMX6Q target configuration
set CHIPNAME imx6q

# function to apply initial configuration after a reset. It
# provides a basic pad configuration and also DDR memory and clocks
# sufficient to load and execute a boot loader (e.g. barebox) from
# DDR memory. This list is extracted from the barebox flash image
# header.
