[v1] aspeed: Add boot from eMMC support (AST2600)

[PATCH 0/8] aspeed: Add boot from eMMC support (AST2600)

Posted by Cédric Le Goater 5 months, 3 weeks ago

From: Cédric Le Goater <clg@kaod.org>

Hello,

This series enables boot from eMMC on the rainier-bmc machine, which
is the default behavior and also on the AST2600 EVB using a machine
option to change the default.

It depends solely on the availability of an eMMC device model which is
currently being discussed upstream. Numerous patches have been merged
already and remaining ones [1] should be in 9.1 development cycle.
Since the changes of this series are small and localized, it would be
an interesting extension of the AST2600 SoC model for QEMU 9.1.

First 6 patches adjust the machine setup and HW strapping to boot from
eMMC, the last 2 are for the AST2600 EVB and are optional.

Thanks,

C.

I built the series using the tree you linked above. It works well!

In that context:
