From 5c2859cdc30287b3593d9df88f48c31eecb0bbed Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 10 Nov 2013 10:27:03 -0700 Subject: sandbox: Allow reading/writing of RAM buffer It is useful to be able to save and restore the RAM contents of sandbox U-Boot either for setting up tests, for later analysys, or for chaining together multiple tests which need to keep the same memory contents. Add a function to provide a memory file for U-Boot. This is read on start-up and written when shutting down. If the file does not exist on start-up, it will be created when shutting down.
