With RHEL7, RedHat decided to stop any 32-bit version of its distribution.
Anticipating the market evolution, the company is now working on a 64-bit ARM architecture called AArch64.
Yesterday, Jon Masters, RedHat ARM architect, gave a conference showing a demo of RHEL7 running on a 64-bit ARM server. This distribution should be released before the end of the year.
