Much confusion because of ARM's really confusing naming schemes...

1. There are ARM architectures:
ARMv1
ARMv2
...
ARMv7
ARMv8

2. There are ARM designs/families:
ARM1
...
ARM7
ARM9
ARM11
ARM Cortex-A (A8, A9, A5, A15, A7, A12, A17)
ARM Cortex-M (M0, M3, M4, M7)
ARM Cortex-R

ARM7 belongs to the ARMv3 architecture and was introduced more than 20 years 
ago.
Your STM32F7 is not an ARM7, it's an ARM Cortex-M7!
Cortex-M3, -M4 and -M7 are all belonging to the ARMv7 architecture.

https://de.wikipedia.org/wiki/ARM-Architektur
https://en.wikipedia.org/wiki/ARM_architecture

The Cortex-M7 is binary compatible to the -M4. It may be that the compiler 
from Adacore doesn't include the latest and greatest optimizations for 
Cortex-M7, but apart from that it should work out of the box. Support for 
the STM32F7 EVAL board (not the DISCO board) is included in the runtime 
delivered with the compiler. Adaption to the DISCO board should be 
manageable.

The already mentioned 'svd2ada' project on Github is still work in progress. 
Its aim is the auto-generation of register declarations, based on the 
manufacturer-supplied CMSIS-SVD files. SVD files should exist for every 
Cortex-M microcontroller (though the quality of these files is varying...)

Matthias
