On read, this register reads bits [27:0] of FPSCR plus the CONTROL.SFPA bit. On write, it doesn't just write back those bits -- it writes a value to the whole FPSCR, whose upper 4 bits are zeroes. We also incorrectly implemented the write-to-FPSCR as a simple store to vfp.xregs; this skips the "update the softfloat flags" part of the vfp_set_fpscr helper so the value would read back correctly but not actually take effect.

This means that the timer being freed must not be currently active, as otherwise QEMU might crash later when the active list is processed and still has a pointer to freed memory on it. As a result almost all calls to timer_free() are preceded by a timer_del() call, as can be seen in the output of git grep -B1 '\<timer_free\>' This is unfortunate API design as it makes it easy to accidentally misuse (by forgetting the timer_del()), and the correct use is annoyingly verbose.

This is always an error for 'cpuclk'. For 'refclk' it is OK for this to be disconnected, but we need to handle it by not trying to connect a sourceless-clock to the systick device. This fixes a bug where on the mps2-an521 and similar boards (which do not have a refclk) the systick device incorrectly reset with SYST_CSR.CLKSOURCE 0 ("use refclk") rather than 1 ("use CPU clock").

Per Akihiko Odaki [*]: An image file, which is being chosen by the panel, can be a raw file and have a variety of file extensions and many are not covered by the provided list (e.g. "udf"). Other platforms like GTK can provide an option to open a file with an extension not listed, but Cocoa can't. It forces the user to rename the file to give an extension in the list. Moreover, Cocoa does not tell which extensions are in the list so the user needs to read the source code, which is pretty bad.
