The update is required to include 3c3ca64b5f0dd9eef7b1ce1c65cc6e8e9147dd38 otherwise baremetal does not on VExpress. baremetal: create a baremetal setup with crosstool-ng buildroot: improve directory location: move out/dl inside out/buildroot/download, and add a new out/buildroot/build level tagline: generalize, deliver more value than howto, since now howtos are starting to multiply rename all top scripts to separate words with hyphen more consistently, e.g. run-gdb instead of rungdb getvar: list all variables gem5: make m5out section to focus all releated information at Prevent m5term Text file busy when rebuilding gem5 while it is running.
