From 90a9901764d71308192c96ecd7d735531fe9cc30 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 1 Nov 2020 14:15:35 -0700 Subject: [PATCH] test: Add some tests for setexpr This command currently has no tests. Add some for basic assignment and the integer operations. Note that the default size for setexpr is ulong, which varies depending on the build machine. So for sandbox on a 64-bit host, this means that the default size is 64 bits.
