v1:
  Add initial support for AST27x0
  The purpose of vbootrom here is to simulate the work of BootMCU SPL (riscv)
  in AST2700, because QEMU doesn't support heterogenous architecture yet.

  ast27x0_bootrom.bin is a simplified, free (Apache 2.0) boot ROM for
  ASPEED AST27x0 BMC SOC. It currently implements the bare minimum to
  load, parse, initialize and run boot images stored in SPI flash, but may grow
  more features over time as needed. The source code is available at:
  https://github.com/google/vbootrom

v2:
  Add "Introduced ASPEED_DEV_VBOOTROM in the device enumeration" patch to fix
  build failed.

v3:
  1. Supports both vbootrom and device loader boot methods, with vbootrom used as
  the default.
  2. Fix review and QTEST test failed issues.
