Yes, JFFS2 itself is not limited to 64bit. However, it's rarely used within U-Boot, and only on 32bit platforms. There's also known security issues and previously when I've asked custodians of boards that use it if they would be interested in fixing the issues, they instead removed JFFS2 support. -- Tom
