From c52b5e8e2ce7f4cd3a9116083debd27ef23046d7 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 20 Oct 2019 21:31:52 -0600 Subject: [PATCH] spl: Add a size check for TPL We have the ability to enforce a maximum size for SPL but not yet for TPL. Add a new option for this. Document the size check macro while we are here.
