Sorry, I wasnât aware of your urgent question.

For ARM spec, please refer to the following link.
http://search.arm.com/search?q=ARM+Architecture+Reference+Manual&site=Site-Search&btnG=Search&entqr=0&getfields=Description&sort=date%3AD%3AL%3Ad1&output=xml_no_dtd&client=Search&ud=1&oe=UTF-8&ie=UTF-8&proxystylesheet=Search

For QEMU for ARM usage issue, please refer to the following forum.
http://qemu-forum.ipi.fi/viewforum.php?f=20&sid=897c9c4a74dc3288be31d7c10bb399b3

Any question, donât hesitate to add me to the âtoâ list. ï
