[PATCH v1 9/9] stm32mp2: initial support
Patrice Chotard

Fri Oct 27 16:43:04 CEST 2023
Add initial support for STM32MP2 SoCs family.
SoCs information are available here :
https://www.st.com/content/st_com/en/campaigns/microprocessor-stm32mp2.html
Migrate all MP1 related code into stm32mp1/ directory
Create stm32mp2 directory dedicated for STM32MP2 SoCs.
Common code to MP1, MP13 and MP25 is kept into
arch/arm/mach-stm32/mach-stm32mp directory :
- boot_params.c
- bsec
- cmd_stm32key
- cmd_stm32prog
- dram_init.c
- syscon.c
- ecdsa_romapi.c
For STM32MP2, it also :
- adds memory region description needed for ARMv8 MMU.
- enables early data cache before relocation.
During the transition before/after relocation, the MMU, initially setup
at the beginning of DDR, must be setup again at a correct address after
relocation. This is done in enables_caches() by disabling cache, force
arch.tlb_fillptr to NULL which will force the MMU to be setup again but
with a new value for gd->arch.tlb_addr. gd->arch.tlb_addr has been
updated after relocation in arm_reserve_mmu().
