Description
Investigate whether to use two-port RAM or one-read-one-write RAM for SPI device.
OpenTitan Darjeeling uses 1R1W: https://github.com/lowRISC/opentitan/blob/05f167eafe75578c855a1794414405311ee69556/hw/top_darjeeling/rtl/autogen/top_darjeeling.sv#L22
OpenTitan EarlGrey uses 2P: https://github.com/lowRISC/opentitan/blob/05f167eafe75578c855a1794414405311ee69556/hw/top_earlgrey/rtl/autogen/top_earlgrey.sv#L23

In Mocha we currently use the default two-port version.

Research direction
Start by comparing the linked OpenTitan top_darjeeling.sv, top_earlgrey.sv, and hw/ip/spi_device/rtl/spi_device_pkg.sv references, then locate Mocha's SPI device SRAM configuration. Determine whether two-port or 1R1W RAM is appropriate for Mocha and document the resulting design decision and rationale.
