talking to rudolf of asics.ws about updating the specs on sd/mmc to eMMC
performance level.  may need a PCB to be designed and made up in order
to test it.  could potentially be done as a break-out board?
Comment 2 Luke Kenneth Casson Leighton 2018-03-25 07:28:22 BST
tracked down JESD84-B51 eMMC 5.1 standard (register on jedec.org)

also need to get hold of sdcard.org SDIO full standard for rudolf.
Comment 3 Luke Kenneth Casson Leighton 2018-05-24 15:34:24 BST
$25k to rudi, 6 months for completion (estimated).
