Re: [PATCH 12/23] arm64: zynqmp: Add mtd partition for secure OS storage area

From: Amit Kumar Mahapatra <redacted>

Update MTD partitions of Kria device trees to allocate 128KB of QSPI
memory for secure OS. Increased "SHA256" partition size & changed
starting address of "User" partition to accommodate the new partition
"Secure OS Storage"
