Terminology

-----------

Uclass - a group of devices which operate in the same way. A uclass provides

   a way of accessing individual devices within the group, but always

   using the same interface. For example a GPIO uclass provides

   operations for get/set value. An I2C uclass may have 10 I2C ports,

   4 with one driver, and 6 with another.

Driver - some code which talks to a peripheral and presents a higher-level

   interface to it.

Device - an instance of a driver, tied to a particular port or peripheral.

spl: add support to booting with OP-TEE

OP-TEE is an open source trusted OS, in armv7, its loading and

running are like this:

loading:

- SPL load both OP-TEE and U-Boot

running:

- SPL run into OP-TEE in secure mode;

- OP-TEE run into U-Boot in non-secure mode;

More detail:

https://github.com/OP-TEE/optee_os

and search for 'boot arguments' for detail entry parameter in:

core/arch/arm/kernel/generic_entry_a32.S

Cover-letter:

rockchip: add tpl and OPTEE support for rk3229

Add some generic options for TPL support for arm 32bit, and then

and TPL support for rk3229(cortex-A7), and then add OPTEE support

in SPL.

Tested on latest u-boot-rockchip master.

END

Series-version: 4

Series-changes: 4

- use NULL instead of '0'

- add fdt_addr as arg2 of entry

Series-changes: 2

- Using new image type for op-tee
