From 4a9be9f32120794e7ea16d7dd5f4490f17dad623 Mon Sep 17 00:00:00 2001 From: Sean Rhodes Date: Sun, 13 Feb 2022 21:19:19 +0000 Subject: payloads/tianocore: Pass SD_MMC_TIMEOUT build option MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit By default, edk2 allows 1000000μs for SD Card Readers and eMMC to initialize which is excessive and causes a boot delay. This makes the value configurable and uses a default of 1000μs which is sufficient for the majority of readers. The value of 1000μs was hardcoded in MrChromeBox's fork for around 2 years with no reported issues.
