[SeaBIOS] Does SeaBIOS support eMMC?

[Scheithauer, Mario]

Now I have a new log with an actual coreboot + SeaBIOS.
Additional I've made the following changes for FSP and coreboot:
FSP - SouthComplex - eMMC Boot Mode - eMMC4.5
FSP - SouthComplex - eMMC45 DDR50 - Enabled
FSP - SouthComplex -eMMC45 HS200 - Enabled
coreboot - gpio.c
  GPIO_FUNC3, /* GPIO_S0_SC[016]	MMC1_CLK		MMC1_45_CLK			 */
  GPIO_FUNC3, /* GPIO_S0_SC[017]  MMC1_D[0]   MMC1_45_D[0]       */
  GPIO_FUNC3, /* GPIO_S0_SC[018]  MMC1_D[1]   MMC1_45_D[1]       */
  GPIO_FUNC3, /* GPIO_S0_SC[019]  MMC1_D[2]   MMC1_45_D[2]       */
  GPIO_FUNC3, /* GPIO_S0_SC[020]  MMC1_D[3]   MMC1_45_D[3]       */
  GPIO_FUNC3, /* GPIO_S0_SC[021]  MMC1_D[4]   MMC1_45_D[4]       */
  GPIO_FUNC3, /* GPIO_S0_SC[022]  MMC1_D[5]   MMC1_45_D[5]       */
  GPIO_FUNC3, /* GPIO_S0_SC[023]  MMC1_D[6]   MMC1_45_D[6]       */
  GPIO_FUNC3, /* GPIO_S0_SC[024]  MMC1_D[7]   MMC1_45_D[7]       */
  GPIO_FUNC3, /* GPIO_S0_SC[025]  MMC1_CMD    MMC1_45_CMD      */
  GPIO_FUNC3, /* GPIO_S0_SC[026]  MMC1_RST#   SATA_DEVSLP[0]  MMC1_45_RST#   */

The sdhci controller on your device is properly detected, so you should not do anything with the "etc/sdcard" settings.

It looks like your eMMC device was detected as well (MMC drive R1J55A 2097151MiB), but then had an error during read.  I need to take a closer look at the logs to try and figure out what went wrong.

BTW, I noticed the build didn't pick up the seabios version - what version are you using and what build environment did you use to compile it?
