Upgrade emulated UART to 16550A (Stefano Stabellini)
...
This patch upgrades the emulated UART to 16550A, the code comes from
xen-unstable. The main improvement was introduced with the following patch and
subsequent email thread:
http://lists.xensource.com/archives/html/xen-devel/2007-12/msg00129.html
The changes compared to previous version are:
- change clock_gettime to qemu_get_clock
- no token bucket anymore;
- fixed a small bug handling IRQs; this was the problem that prevented
kgdb to work over the serial (thanks to Jason Wessel for the help
spotting and reproducing this bug).
- many many style fixes;
- savevm version number increased;
- not including termios.h and sys/ioctl.h anymore, declaring static
constants in qemu-char.h instead;
