[PATCH 0/3] mmc support for QEMU

[Harm Berntsen]

Hi,

This patch series allows you to use a mmc drive from within QEMU:

1. make qemu_arm_defconfig
2. Enable the CONFIG_DM_MMC, CONFIG_MMC_PCI, CONFIG_MMC_SDHCI options
3. Run quemu as follows:

?? qemu-system-arm
?? -machine virt,highmem=off \
?? -device sdhci-pci \
?? -device sd-card,drive=mydrive \
?? -drive id=mydrive,if=none,format=raw,file=mmcblk0.bin \
?? -bios u-boot.bin

The MMC image can now be used to boot :)

Regards,
Harm

I don't see changes made to qemu_arm_defconfig. Is that a future patch?

Hi,

I didn't include changes in the defconfig because you need to manually
add the device to the QEMU virt machine via the command line. On the
other hand the u-boot binary size does not really matter for QEMU
environments. For CI it will also be nice to ensure this set-up will
build.

I'll send in a patch for the config when this series has been merged!

Kind regards,
Harm
