[PATCH 0/7] ARM: Add i.MX93 OP-TEE support

[Sascha Hauer]

This enables OP-TEE support for i.MX93. This is done in a way very
similar to how it's done on i.MX8M.
One major difference is that the i.MX93 needs a RAM firmware for the
EdgeLock secure enclave. Without it OP-TEE doesn't work properly.
The firmware can be integrated into the i.MX93 image where the ROM
picks it up automatically. The firmware image is SoC revision specific
though, so we load the firmware during runtime to avoid having to
create a barebox image for each SoC revision.

Sascha Hauer (7):
  firmware: add missing FIRMWARE_IMX8MQ_OPTEE symbol
  firmware: add missing include
  firmware: i.MX OP-TEE: Add some Kconfig help
  ARM: i.MX93: add imx93_barebox_entry()
  ARM: i.MX: export imx9_ddrc_sdram_size()
  ARM: i.MX93: add scratch space support
  ARM: i.MX93: Add OP-TEE support
