From e85497a930b21cc5b2c5ac220c9ed1668341d30c Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Sun, 7 Jun 2020 18:47:35 +0200 Subject: sandbox: make RAM size configurable Up to now the RAM size of the sandbox is hard coded as 128 MiB. This does not allow testing the correct handling of addresses outside the 32bit range. 128 MiB is also rather small when tracing functions where the trace is written to RAM. Provide configuration variable CONFIG_SANDBOX_RAM_SIZE_MB to set the RAM size in MiB. It defaults to 128 MiB with a minimum of 64 MiB.
