set_segment_base_addr()

uintptr_t set_segment_base_addr	(	s32	segment,
		void *	addr )

Stores the physical memory addr for segmented memory in gSegmentTable using the segment number as an index.

This function takes a segment number and a pointer to a memory address, and stores the address in the gSegmentTable array at the specified segment index. The stored address is truncated to a 29-bit value to ensure that it fits within the memory address. This allows converting between segmented memory and physical memory.

Parameters

segment	A segment number from 0x0 to 0xF to set the base address.
addr	A pointer containing the physical memory address of the data.

Returns

The stored base address, truncated to a 29-bit value.
