This patchset adds support for DMC-620 memory controller's 1-bit DRAM
ECC error reporting and handling.

The first patch implements the handling of the DMC's DRAM errors. The
driver installs a handle that implements the Get HEST rrror source
descriptors protocol. At boot time the handle gets queried and DMC's
error source information is collected from the driver. The driver
supports 1-bit ECC DRAM RAS errors for multiple DMC instances. At
runtime, on RAS interrupt the DRAM handler reads the corresponding
error record syndrome registers and builds Error Status Block which
the OS uses to take appropriate actions.

The rest of the patches in the series enable support HEST and SDEI
table generation and enables firmware-first handling of DMC-620
memory controller's 1-bit DRAM ECC error.

Omkar Anand Kulkarni (6):
