Detailed Description

GDDR CA calibration table, stored in the gddrcal flash partitions.

Entries are indexed [asic][controller], where the ASIC index is the board ASIC location (0 on single-ASIC boards, 0/1 on P300, SPI-provisioned UBB-local location on Galaxy). This lets a single provisioned table image be written to every ASIC's flash; each SMC only reads and updates its own row.

This is the payload only. The on-flash framing (magic, sequence number, version, CRC) and the A/B bank protocol that makes updates power-loss safe are private to gddr_cal.c.
