[SeaBIOS] "ata_piix device not availabile cannot reserve io" issue

[Riccardo Schirone]

Hi, i use seabios on qemu with Linux as guest OS and i am not able to boot
my machine because kernel says

ata_piix 0000:00:01.1: device not available (can't reserve [io
0x0000-0x0007])

i try with qemu v1.5.50 and v.1.4.2 and i have the same error.

Bisecting seabios i found that the error was introduced with this commit

76e58028d28e78431f9de3cee0b3c88d807fa39d - acpi: Eliminate BDAT parameter
passing to DSDT code.

the last good commit is:

3f8d735dd85edc9fc4da8d4018925012a8626877 - Rename src/ssdt-susp.dsl to
src/ssdt-misc.dsl.
