What happened to FSMC?

Many of the "older MCUs" like STM32F4xx had an FSMC. I've been thinking about switching to the newer STM32F7xx and have bought a Discovery board for STM32F7508, but there are no references to FSMC in the documentation. Apparently F765/7/8/9 have a "Flexible external memory controller but I don't know how it differs from FSMC. What happened to FSMC? Which STM32F7xx, STM32Lxx, STM32Hxx, STM32Gxx, etc. products can be used to drive old-style 16 bit parallel bus LCDs?

FMC seems the replacement of FSMC... after this, to look and compare the reference manual understanding what has changed in the new IP. Unless there is a migration guide somewhere.

FMC = FSMC + SDRAM controller
