ast10x0_board

Board-level integration crate for AST10x0 platforms.

This crate owns board-level hardware initialization and board-selected SGPIOM configuration for AST10x0 targets.

Responsibilities

• Apply board pinctrl groups via SCU
• Gate/reset board-level peripherals needed at boot (currently I2C flow)
• Export board descriptor metadata used by runtime init
• Consume generated SGPIOM configuration selected at board build time

SGPIOM policy is board-owned here, while SGPIOM execution remains in //target/ast10x0/peripherals.

SGPIOM JSON Pipeline (Bazel)

The board package wires SGPIOM JSON tooling into Bazel with these targets:

• //target/ast10x0/board:sgpiom_validate
• //target/ast10x0/board:sgpiom_merged
• //target/ast10x0/board:sgpiom_generate
• //target/ast10x0/board:sgpiom_check
• //target/ast10x0/board:sgpiom_report

Generated artifact compiled into this crate:

• sgpiom_config_generated.rs

See //tools/sgpiom/README.md for CLI details and manifest format.
