[GitHub] [incubator-nuttx] eenurkka opened a new pull request, #7047: risc-v/mpfs: emmcsd: allow switching from SD to eMMC

eenurkka opened a new pull request, #7047:
URL: https://github.com/apache/incubator-nuttx/pull/7047

   If the system starts up using the SD-card, and later wants to switch to use the eMMC, it's not going to happen. SD-card will be kept selected within the FPGA making the transition fail.
   
   It's been possible to switch from eMMC to SD, but now the transition is possible for both directions.
   
   Signed-off-by: Eero Nurkkala <ee...@offcode.fi>
   
   ## Summary
   
   Switching from SD-card -> eMMC is possible. Fix this issue. At power-on, eMMC is selected. If SD-card is used by a hart, and later eMMC is needed, this doesn't happen.
   
   ## Impact
   
   MPFS Icicle
   
   ## Testing
   
   Icicle Polarfire kit, NuttX bootloader at hart0 which loads data from SD card, and starts another NuttX (hart1) that uses eMMC.
