Extended Board Revision Usage #276
Description
Has adding the extended revision which can be obtained by mailbox command been discussed?
raspberrypi/firmware#1831
Bit 30 at 0 represents eMMC being present, 1 represents SD being present
It would be ideal to have code that initiates either SD card or eMMC based on what hardware the extended revision code points to. Since there are differences in the code for eMMC and SD, this would simplify the process.
I'm currently trying to make eMMC work on my CM5, but I'm new to edk2 and there is quite a bit of sdhci related code to sift through.
