[PATCH 0/5] Add ESM driver support for AM64x R5

[PATCH 0/5] Add ESM driver support for AM64x R5

[Hari Nagalla]

AM64x devices have a main ESM and a MCU ESM. The ESM driver enables
routing of the error events from various sources to different processors
or to reset hardware logic. Only the MCU ESM's high output can trigger
reset logic. The main RTI0 WWDT output can be routed to the MCU
highoutput to trigger reset through the main ESM. For this reset to
occur CTRLMMR_MCU_RST_CTRL:MCU_ESM_ERROR_RESET_EN_Z is set to '0'.

Sorry.. The patches are being re-submitted after rebasing.

Thanks

Are there any plans to send out a V2 of this patch series? If not I
can jump in (as I really
want to see in U-Boot sooner than later).
