Great!

For code update support, I’ll be pushing changes to gerrit for 
phosphor-bmc-code-mgmt today/tomorrow to support eMMC.
On the build side, there are a few WIP changes that I’ll be refreshing 
this week as well, will tag them as ‘mmc’ on gerrit to be able to 
find them, some previous commits have the topic ‘wic’ and ‘mmc’ 
already but are in Abandoned or WIP, will be cleaning them up this week.
Updates to the emmc doc: 
https://gerrit.openbmc-project.xyz/c/openbmc/docs/+/28443

Ping me on IRC, any time during the day CST time, or if it's later at 
night like 8/9pm CST time we can have Joel/Andrew J join us as well.

Thanks Adriana.

I will ping you on IRC. Can you please add me and Surya to all of the 
eMMC reviews.

Do we have any document on the image build changes that needed for eMMC?

Done.

The design doc alludes to the changes needed but does not exactly spell 
out what files need to be created/changed - 
https://gerrit.openbmc-project.xyz/c/openbmc/docs/+/28443

Most of the build changes are now up in gerrit for review. Leave a 
comment if you have any questions or feedback.

In summary:
u-boot: Pending.
kernel: fitImage as a file in first partition mmcblk0p1 configured as an 
ext4 filesystem mounted on /boot/
user space: device mappers in second partition mmcblk0p2

Secure boot will be addressed at a future iteration.
