Struct memory_aarch64::AggregatedSectionMemoryBounds

pub struct AggregatedSectionMemoryBounds {
    pub init: SectionMemoryBounds,
    pub text: SectionMemoryBounds,
    pub rodata: SectionMemoryBounds,
    pub data: SectionMemoryBounds,
}

The address bounds and flags of the initial kernel sections that need mapping.

Individual sections in the kernel’s ELF image are combined here according to their flags, as described below, but some are kept separate for the sake of correctness or ease of use.

It contains three main items, in which each item includes all sections that have identical flags:

• The text section bounds cover all sections that are executable.
• The rodata section bounds cover those that are read-only (.rodata, .gcc_except_table, .eh_frame).
  • The rodata section also includes thread-local storage (TLS) areas (.tdata, .tbss) if they exist, because they can be mapped using the same page table flags.
• The data section bounds cover those that are writable (.data, .bss).
