Dear ARM porters,
I like to know what is the minimum CPU level for armel and armhf.
Minimum CPU level for debian armel is armv4t
Minimum CPU level for debian armhf is armv7-a
Derivatives may of course adjust these minimums.
Also be aware that debian armhf defaults to compiling C code and
inline assembler within C files in thumb2 mode.
In particular is support for the following assembly instructions required ?

Says these have been arround since V3M and V4 so they are fine for both
debian arm ports.

Says this is available armv5 and above so it's ok for debian armhf but not
for debian armel.
