Subject: Make MemTest* catch reading too many words.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=373630164e91cefbd104c132b9b400d10d9e193b;p=riscv-tests.git

Make MemTest* catch reading too many words.

For one of the test addresses, use the highest possible one to ensure
that OpenOCD isn't secretly reading/writing more words than requested.
