[PATCH u-boot v2019.04-aspeed-openbmc 0/6] Runtime control of vboot via GPIO

[Andrew Jeffery]

Hello,

This u-boot series implements support for controlling whether verified
boot is enabled at runtime by measuring the state of the
"bmc-secure-boot" GPIO for AST2600-based BMCs.

Previously, whether or not verified boot was required was configured at
build time.

These patches build on top of the series Eddie recently sent to the list
to enable use of GPIOs in the SPL:

https://lore.kernel.org/openbmc/20220124191503.88452-1-eajames@linux.ibm.com/

I've tested the changes under qemu, and they behave as expected for the
Rainier platform configuration.

I'll figure out how we go about upstreaming the series once Eddie's
series has been picked up.

Please review!

Andrew
