Multiboot Firmware Root Redirect
Firmware now includes rudimentary redirect functionality but this only supports /.rockbox in the root of the device This patch allows loading external drive and directory into root namespace Root Redirects can now be put into different folders For instance placing '/_test' into SD1/rockbox_main.<playername> will redirect to /<1>/_test/.rockbox Debug menu>Bootdata now has root directory listed in addition to RAW Bootdata Redirect root work from Michael Sevakis g#1556 Redirect will be updated if code refactor is ever done Requires Multiboot bootloader (already in main) Change-Id: I697b3d0499f85e789c3020bc2133fbe0023f72a2
