You can do this by adapting the Linux config using a text editor
(editing .config or arch/arm/configs/YOUR_CONFIG) or tools like 'make
menuconfig'. For information on Linux configs in general or on how to
use related tools, please refer to the varied online documentation. For
information on what to adapt, you can have a look at the Linux commit I
posted in my last mail [2] as it consequently disables ESDHC too.

No. You might ignore the data aborts and simply continue VM execution
but I assume that this would lead to more or less critical errors in Linux.
