[v4] Support vbootrom for AST2700

[PATCH v4 10/10] docs/system/arm/aspeed: Support vbootrom for AST2700

Posted by Jamin Lin via 7 months ago

Using the vbootrom image support and the boot ROM binary is
now passed via the -bios option, using the image located in
pc-bios/ast27x0_bootrom.bin.

Currently, we have 2 sections for the Aspeed boards :

1. Aspeed family boards (ast2500-evb, ast2600-evb, ast2700-evb, ast2700fc, bletchley-bmc, fuji-bmc, fby35-bmc, fp5280g2-bmc, g220a-bmc, palmetto-bmc, qcom-dc-scm-v1-bmc, qcom-firework-bmc, quanta-q71l-bmc, rainier-bmc, romulus-bmc, sonorapass-bmc, supermicrox11-bmc, supermicrox11spi-bmc, tiogapass-bmc, witherspoon-bmc, yosemitev2-bmc)
2. Aspeed minibmc family boards (ast1030-evb)

The first is quite big and relatively consistent for the AST2400, AST2500
and AST2600 SoCs. Since the AST2700 SoC boards boot differently, I think
it is time to introduce a new section for the ast2700 machines.


Thanks,

C.

Thanks for review.
Will create a new section for the AST2700.
