hdsktimeout
The Warm Reset handshake time-out controls the amount of time to wait for the ETR, FPGA and SDRAM interface to respond to a reset handshake request. The register defaults to 10,240 l4_sys_free_clk cycles, which at 100 MHz will be 102.4 micro-seconds. This value will be a 25 bit programmable value in SW. The maximum programmable value would be 2^25-1 l4_sys_free_clk cycles.

Access mode: PRIVILEGEMODE
Note: The processor must make a privileged bus access to this register. You can configure processor mode settings in the control registers of the ARM Cortex-A53 MPcore processor. For more information about processor modes, please refer to the ARM Infocenter.
Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.
