    doc: Reformat platform port documents · 24dba2b3
    Paul Beesley authored 
    
The platform port documents are not very standardised right now and
they don't integrate properly into the document tree so:

1) Make sure each port has a proper name and title (incl. owner)
2) Correct use of headings, subheadings, etc in each port
3) Resolve any naming conflicts between documents

Xilinx Versal

Trusted Firmware-A implements the EL3 firmware layer for Xilinx Versal. The platform only uses the runtime part of TF-A as Xilinx Versal already has a BootROM (BL1) and PMC FW (BL2).

BL31 is TF-A. BL32 is an optional Secure Payload. BL33 is the non-secure world software (U-Boot, Linux etc).

To build: `bash make RESET_TO_BL31=1 CROSS_COMPILE=aarch64-none-elf- PLAT=versal bl31 `

To build ATF for different platform (for now its just versal virtual "versal_virt") `bash make RESET_TO_BL31=1 CROSS_COMPILE=aarch64-none-elf- PLAT=versal VERSAL_PLATFORM=versal_virt bl31 `

Xilinx Versal platform specific build options

  • VERSAL_ATF_MEM_BASE: Specifies the base address of the bl31 binary.
  • VERSAL_ATF_MEM_SIZE: Specifies the size of the memory region of the bl31 binary.
  • VERSAL_BL32_MEM_BASE: Specifies the base address of the bl32 binary.
  • VERSAL_BL32_MEM_SIZE: Specifies the size of the memory region of the bl32 binary.
  • VERSAL_CONSOLE: Select the console driver. Options: - pl011, pl011_0: ARM pl011 UART 0 - pl011_1 : ARM pl011 UART 1
  • VERSAL_PLATFORM: Select the platform. Options: - versal_virt : Versal Virtual platform
