[PATCH 0/3] Implement the watchdog timer of HiFive 1 rev b.

Posted by Tommy Wu 3 years, 4 months ago

The HiFive 1 rev b includes a watchdog module based on a 32-bit
counter. The watchdog timer is in the always-on domain device of
HiFive 1 rev b, so this patch added the AON device to the sifive_e
machine. This patch only implemented the functionality of the 
watchdog timer, not all the functionality of the AON device.

You can test the patchset by the QTest tests/qtest/sifive-e-aon-watchdog-test.c

Tommy Wu (3):
  hw/misc: sifive_e_aon: Support the watchdog timer of HiFive 1 rev b.
  hw/riscv: sifive_e: Support the watchdog timer of HiFive 1 rev b.
  tests/qtest: sifive-e-aon-watchdog-test.c : Add QTest of watchdog of
    sifive_e
