This structure defines an XIP region.
typedef struct ROMChain_t{ struct ROMChain_t* pNext; ROMHDR* pTOC; } ROMChain_t, OEMRomChain;
Pointer to the next XIP region if one exists.
Pointer to the table of contents of the ROM for this XIP region.
An OEM can specify the ROMChain ordering of all XIPs.
If the ROM where the kernel resides cannot be found by traversing OEMRomChain, the kernel will automatically append this ROM to the OEMRomChain list.
