[PATCH 1/3] hw/hppa/machine: Correctly check the firmware is in PDC rang

From: Philippe Mathieu-Daudé
Subject: [PATCH 1/3] hw/hppa/machine: Correctly check the firmware is in PDC range
Date: Wed, 8 Jan 2020 19:14:23 +0100

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.

Signed-off-by: Philippe Mathieu-Daudé <address@hidden>
Note we define FIRMWARE_END=0xf0800000 but in the specs
the PDC ends at 0xf1000000.
