[SeaBIOS] Possibility to merge the SeaBIOS-parisc tree?

Dear SeaBIOS developers, a few years back I forked the SeaBIOS sources to create a SeaBIOS firmware for usage with the parisc/hppa architecture. This fork is on github: https://github.com/hdeller/seabios-hppa Main goal of this fork was to provide a firmware which can be used to boot a virtual

[SeaBIOS] [PATCH 10/31] Add portaddr_t typedef to specify I/O port addresses

On x86 I/O ports are located below address 0x4000, while on PA-RISC I/O ports are allowed in the whole 32/64 bit address space. So, introduce a portaddr_t typedef which defaults to the current u16 type on x86 and to unsigned long on PA-RISC. Signed-off-by: Helge Deller --- src/hw/ata.c
