ROM does not support OSPI 8D boot mode for the flashes supporting extended opcode

Details:

Boot ROM reads SFDP header from flash memory after switching to 8D mode for adjusting the read tap delays. A5h command is used to read the SFDP header. Flashes that support extended Opcode expect A5h followed by 5Ah or A5h based on inverse or repeat to be sent by ROM. This is not supported in ROM code.

This issue applies only for the flash memories that need extended opcode support in 8D boot mode. 1S and 8S boot modes are not impacted by this issue.

Workaround(s):

None. Use the Flash memories that do not require extended OPCode
