Anyone with Pi hardware, could you record a bootchart from a core boot?
I don't have such hw myself, and it would be interesting to see how it looks on a Pi, given the different architecture and the slow cpu.
The instructions on the wiki:
http://wiki.tinycorelinux.net/wiki:bootchartshould apply, but the binaries in the tarball need to be replaced with ARM ones (source is also linked in the page).
