[PATCH REPOST v3 39/80] hw/hppa/machine: Correctly check the firmware is in PDC range

Posted by Igor Mammedov 6 years ago

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

The firmware has to reside in the PDC range. If the Elf file
expects to load it below FIRMWARE_START, it is incorrect,
regardless the RAM size.
