Re: [PATCH] cmd: sf: prevent overwriting the reserved memory

Added LMB API to prevent SF command from overwriting reserved memory areas. The current SPI code does not use LMB APIs for loading data into memory addresses. To resolve this, LMB APIs were added to check the load address of an SF command and ensure it does not overwrite reserved memory addresses. Similar checks are used in TFTP, serial load, and boot code to prevent overwriting reserved memory.

This is a much more generic issue that should be looked in to with the LMB rewrite that Sughosh is working on.
