Subject: [PATCH v2 1/3] hw/hppa/machine: Correctly check the firmware is in PDC range
Date: Thu,  9 Jan 2020 01:05:23 +0100	[thread overview]
Message-ID: <20200109000525.24744-2-f4bug@amsat.org> (raw)
In-Reply-To: <20200109000525.24744-1-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.
