The EBOOTCNT is a reserved persistent static memory area in QRIO,
and similar to BOOTCNT is intended to be used as boot counter location.
Comparable to BOOTCNT that is reserved for u-boot main bootcount
infrastructure, EBOOTCNT is intended to be used for pg-wcom board
specific purposes (e.g implementing early boot counter for fail-safe
u-boot update).

It is necessary to read the status of the PGY_PRES pin
so that u-boot can react accordingly.

There is a request from HW designers to use this QRIO pin for detecting
DIC26_SELFTEST status instead of a GPIO pin.
This pin is typically used during production for executing POST tests and
starting test ESW bank.

The CPUWD reset reason is used for kmp204x.
And the qrio cpu reset request is configured to operate in
core reset mode.
But for the evaluation of the qrio's reset reason register
the CPUWD figures as a unit reset source rather than a core
reset source. This patch defines the CPUWD reset as a core
reset source when evaluating the reset reason register.
