- Synthesizable. Simulations reveals some little bugs in SPI cs_n pin and no loading of the registers.
- The VHDL syntax uses extensively type record entities, translation functions between IOs and records, attributes for defined type records...
- m25p32_core.vhd has now a package for itself m25p32_core_pkg.vhd. This file contains procedures for all the chain of spi instruction to write and read from the memory through SPI. It needs to add more cases.

It still needs work to do.
