dear exports,
I am porting optee to imx6solo processor, I have three questions here.
1. in imx6.h, there are the following code:
#if defined(CFG_MX6QP) || defined(CFG_MX6Q) || defined(CFG_MX6DL) || \
defined(CFG_MX6D)
#define TZASC2_BASE 0x21D4000
#define TZASC2_SIZE 0x4000
#endif
I see in the i.MX6solo/6duallite reference manual that there are two TZASCs, do I need to add the following line:
before the line #else to the following code?
#if defined(CFG_MX6QP) || defined(CFG_MX6Q) || defined(CFG_MX6DL) || \
defined(CFG_MX6D)||(CFG_MX6S) because there are two TZASCs?
2. For 6solo, there are only 128k OSCRAM, do I need to modify the following code:
if defined(CFG_MX6UL) || defined(CFG_MX6ULL)
/* 128K OCRAM */
#define TRUSTZONE_OCRAM_START 0x918000
#elif defined(CFG_MX6DL)
#define TRUSTZONE_OCRAM_START 0x918000
#elif defined(CFG_MX6QP)
#define TRUSTZONE_OCRAM_START 0x938000
#elif defined(CFG_MX6SX)
#define TRUSTZONE_OCRAM_START 0x8f8000
#elif defined(CFG_MX6SL)
#define TRUSTZONE_OCRAM_START 0x918000
#elif defined(CFG_MX6SLL)
#define TRUSTZONE_OCRAM_START 0x918000
#else
/* 256K OCRAM */
#define TRUSTZONE_OCRAM_START 0x938000
#endif
#elif defined(CFG_MX6S)
#define TRUSTZONE_OCRAM_START 0x918000
3. in driver/tzc380.c, do I need to add ||IS_ENABLED(CFG_MX6S) to the following line?
if (IS_ENABLED(CFG_MX6Q) || IS_ENABLED(CFG_MX6D) ||
IS_ENABLED(CFG_MX6DL))
4. Do I need to add $(call force,CFG_TZC380,y) to the following code in conf.mk?
else ifneq (,$(filter $(PLATFORM_FLAVOR),$(mx6s-flavorlist)))
$(call force,CFG_MX6,y)
$(call force,CFG_MX6S,y)
$(call force,CFG_TEE_CORE_NB_CORE,1)
thank you all!

Hi
in general optee is already supported in nxp linux releases, no need for porting.
One can select "imx6solosabresd" machine configuration as described in sect.5.1 Build configurations
i.MX Yocto Project User’s Guide and follow sect.5.6.10 OP-TEE enablement.
Best regards
igor
Dear igor,
I have a new board name, when I build the image, it says optee does not support the board. Do I just need to append the board name as the following?
mx6s-flavorlist = \
mx6shmbedge \
mx6solosabresd \
mx6solosabreauto \
new_board_name \
thanks a lot!
