Function Documentation

sunxi_ansc_boot()

void sunxi_ansc_boot

(

uint32_t

addr

)

Boot the A27L2 processor.

This function configures clocks, reset controls, and cache settings to boot the A27L processor. It performs a series of hardware register operations to ensure the processor is in the correct state during boot-up.

Parameters

addr	The address to start the A27L processor. This is typically the entry point of a program or firmware.

Note

• This function disables interrupts on entry and performs necessary clock and reset settings before booting the A27L2 processor.
• Ensure that relevant registers and addresses are properly initialized before calling this function.
• The function uses assembly instructions to directly manipulate hardware registers, thus requiring the compiler to understand the embedded assembly code.

Warning

• Make sure the relevant hardware state is ready before invoking this function to avoid undefined behavior.
