@
|

@ All 64-bit capable Allwinner SoCs reset in AArch32 (and continue to
|
||||
@ exectute the Boot ROM in this state), so we need to switch to AArch64
|
||||
@ at some point.
|
||||
@ Section G6.2.133 of the ARMv8 ARM describes the Reset Management Register
|
||||
@ (RMR), which triggers a warm-reset of a core and can request to switch
|
||||
@ into a different execution state (AArch32 or AArch64).
|
||||
@ The address at which execution starts after the reset is held in the
|
||||
@ RVBAR system register, which is architecturally read-only.
|
||||
@ Allwinner provides a writable alias of this register in MMIO space, so
|
||||
@ we can easily set the start address of AArch64 code.
|
||||
@ This code below switches to AArch64 and starts execution at the specified
|
||||
@ start address. It needs to be assembled by an ARM(32) assembler and
|
||||
@ the machine code must be inserted as verbatim .word statements into the
|
||||
@ beginning of the AArch64 U-Boot code.
|
||||
@ To get the encoded bytes, use:
|
||||
@ ${CROSS_COMPILE}gcc -c -o rmr_switch.o rmr_switch.S
|
||||
@ ${CROSS_COMPILE}objdump -d rmr_switch.o
|
||||
@
|
||||
@ The resulting words should be inserted into the U-Boot file at
|
||||
@ arch/arm/include/asm/arch-sunxi/boot0.h.
|
||||
@
|
||||
@ This file is not build by the U-Boot build system, but provided only as a
