From: Helge Deller <del...@gmx.de> All 32-bit hppa CPUs allow a fixed number of TLB entries to have a different page size than the default 4k. Those are called "Block-TLBs" and are created at startup by the operating system and managed by the firmware of hppa machines through the firmware PDC_BLOCK_TLB call.
This patchset adds the necessary glue to SeaBIOS-hppa and qemu to allow up to 16 BTLB entries in the emulation.
