I have a design that needs to read/write data to a RAM from a JTAG connection.Before starting to write my own VHDL controller, I was wondering: are there any Xilinx primitives that allow JTAG-accessible RAMs ?

The PicoBlaze (kcpsm6/kcpsm3) JTAG bootloader also does this (writes -> BRAM port via JTAG operations).
See the documentation for the full details.
