[U-Boot] [PATCH 00/11] Enable Windows 10 IoT Core on i.MX6 and i.MX7

[Henry Beberman <Henry.Beberman@microsoft.com>]

From: Henry Beberman <henry.beberman@microsoft.com>

This patch series is a collaboration between Microsoft and NXP to
enable Windows 10 IoT Core on NXP's iMX6 and iMX7 platforms.

The series contains reference configurations to enable Windows boot on the following
platforms: mx6sabresd, mx7dsabresd, mx6cuboxi, udoo_neo, and cl-som-imx7

These patches enable the following Windows boot flow:
1) U-Boot SPL loads from the MMC into on-chip RAM.
2) SPL loads a Flat Image Tree containing the OP-TEE runtime and U-Boot Proper.
3) SPL disables caches/interrupts and jumps into OP-TEE.
4) OP-TEE initializes then returns to the entry point of U-Boot
Proper in normal mode. OP-TEE is later used as a runtime for Trusted Applications from within Windows.
5) U-Boot Proper initializes the platform bypassing several actions
that would require secure world access.
6) The U-Boot Proper bootcmd loads a UEFI firmware binary from the
first FAT partition of the MMC into memory.
7) An overridden go command will stash the platform MAC address
from the U-Boot env into a page of memory that is preserved for UEFI.
8) The overridden go command will disable caches and interrupts then
jump into UEFI.
9) UEFI initializes the platform further and boots Windows from MMC.

Henry Beberman (11):
  imx: Add bootcmd to load and run UEFI from mmc
  arm: Allow U-Boot Proper to run in normal world
  spl: Add FIT boot into OP-TEE then U-Boot proper
  spl: imx: Add optional lds to keep SPL entirely in on-chip RAM
  mx6sabresd: nt: Add Windows boot support for iMX6 Sabre
  mx7dsabresd: Add Windows boot support for iMX7 Sabre
  mx6cuboxi: Add Windows boot support for mx6cuboxi
  udoo_neo: Add Windows boot support for UDOO Neo
  cl-som-imx7: Add Windows boot support for cl-som-imx7
  imx: Reserve a global page in memory to pass configuration to UEFI
  imx: Add MAC addresses to global page to pass MAC into UEFI
