#opt	Id	Name		Type		Device	Offset		Binary
-	0x01	fsbl_boot	Binary		none	0x0		tf-a-stm32mp157f-dk2-mx.stm32
-	0x03	fip_boot	Binary		none	0x0		fip.bin
P	0x10	sdcard		RawImage	mmc0	0x0		sdcard.img


Opt:

- '-' : no action
  
- 'P' : update = program the partition or the flash device
  
- 'PE' : do not update (also 'EP') : allow GPT partitioning with empty partition for block device but equivalent to '-' for RAW flash device
  
- 'PD' : delete and update (also 'DP’)
  
- 'PDE' : delete and keep empty (also 'PED' / 'DPE' / 'DEP' / 'EPD' / 'EDP’)


ID fields :

- Two ranges :

  - 0x01 to 0x0F Boot partitions with FIP header: file containing SSBL or with STM32 header: FSBL or other without
    header: metadata
    
  - 0x10 to 0xF0 user partitions programmed without header (uimage, dtb, rootfs, vendorfs, userfs)
    
- Reserved Id :
  
  - 0x00 FlashLayout (used internally, cannot be used in FlashLayout file)
  - 0x01 FSBL (first copy) : used by ROM code (load in RAM)
  - 0x03 SSBL : used by FSBL=TF-A (load in RAM)
  - 0xF1 to 0xFD "virtual partition": used internally

Optee/Trusted(OpenSTLinux看得到)
openSTLinux在4以後，只用Optee
