[Xen-devel] [PATCH v3 09/20] hw/mips/mips_malta: Create IDE hard drive array dynamically

[Philippe Mathieu-Daudé <philmd@xxxxxxxxxx>]

In the next commit we'll refactor the PIIX4 code out of
mips_malta_init(). As a preliminary step, add the 'ide_drives'
variable and create the drive array dynamically.
