A new Flyspray task has been opened.  Details are below.

Attached to Project - OpenWrt/LEDE Project
Summary - X86 kernel has no emmc support, cause it can't boot from emmc only X86-64 devices
Task Type - Bug Report
Category - Base system
Status - Unconfirmed
Assigned To - 
Operating System - All
Severity - High
Priority - Very Low
Reported Version - Trunk
Due in Version - Undecided
Due Date - Undecided
Details - Supply the following if possible:
 - Device problem occurs on: Z83II mini pc. https://www.minipcdb.com/articles/Meet-Z83II-Mini-PC
 - Software versions of OpenWrt/LEDE release, packages, etc.  Tested on both 19.07.3 and latest snapshots, both failed.
 - Steps to reproduce: Write to image to the embedded emmc disk and boot it.

I’ve tested both 19.07.3 and latest snapshots build of openwrt x86-64 build on the Intel Z8350 fanless mini PC. Both failed to boot. The kernel can boot up correctly, but the system hang at waiting for root device. If the image is burned on USB disk, it can boot up correctly without any issue. 

I searched on Google and found this post - https://forum.archive.openwrt.org/viewtopic.php?id=72195

I did the test on 19.07.3 and verified the system can boot up correctly from embedded emmc storage that by adding the following two options into the target/linux/x86/64/config-default file 
CONFIG_MMC_SDHCI_ACPI
CONFIG_X86_INTEL_LPSS

Could you approve to add the options into the future update to support booting from emmc storage?
Thanks!
