[U-Boot] [PATCH v3 00/11] rockchip: add tpl and OPTEE support for rk3229

[U-Boot] [PATCH v3 00/11] rockchip: add tpl and OPTEE support for rk3229

[Kever Yang]

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.


Changes in v3:
- do not init ddr region in spl

Changes in v2:
- update subject with ARCH_MEM info
- Add new image type like ATF
- Using new image type for op-tee
- Make the its as common file used for all armv7 with op-tee
- update defconfig option

Kever Yang (11):
  lib: add TPL_OF_LIBFDT option for TPL
  arm: add option for TPL ARCH_MEM in arm 32bit
  arm: add a separate stack for TPL
  rockchip: rk322x: enable tpl support
  sysreset: enable driver support in SPL/TPL
  image: add os type for OP-TEE
  spl: add support to booting with OP-TEE
  rockchip: rk322x: dts: enable uart2 for SPL/TPL
  rockchip: add fit source file for pack itb with op-tee
  rockchip: evb-rk3229: add README file for OP-TEE support
  rockchip: evb-rk322x: update defconfig with tpl and optee support

Most of these defines are not used in the code below.
Please remove.

If possible please use the DM timer class and the rockchip_timer.c
driver as a timebase for U-Boot (I assume that the secure timer will
be set up by OP-TEE anyway)... this should render this initialisation
unnecessary.

Again: by using the DM timer drivers, you won't need to call the
rockchip_timer_init (as the init will be done by the DM timer).

Please use syscon to get the SGRF base-address and access this through
the SGRF structure definition.

I agree DM is good framework in U-Boot proper, but maybe not in TPL/SPL.
Framework cost more code space and running time, but we get benefit for its
comment code and compatibility.
To be honest, I don't like use too much framework in TPL which is in IRAM,
I want to make it as simple as possible, and also need clear enough with 
comments.
I will consider what to use framework and what to use hard code in TPL/SPL,
we need to balance it but not use DM everywhere:
DEBUG_UART/SERIAL/SYSCON/PINCTRL/CLOCK/

Secure timer must be setup before trust(OPTEE/ATF) for all rockchip 
platform now,
U-Boot proper can not access it, it's the clock source of arm generic timer.
we can consider using arm generic timer as time base and drop 
rockchip_timer.c when we
use DM framework, I think the rockchp_timer.c is used for chip like 
rk3036 who can not
use any framework because of the IRAM size limit.

Sorry, I don't think this one time init, need introduce syscon(more code 
space and instructions with
no any other help), it's different in different soc, and it's only 
available in TPL or SPL(if no TPL support).
I would like to make it as-is and with clear enough comments.

Thanks,

[Kever Yang]

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;

Why are you passing '0' for "arg2, device tree address"? This should
be the device-tree pointer from the spl_image...

Also: 0 is not the same as NULL ... the arguments are all defined to
have void* type, so 0 is not the correct type.

This doesn't look like a documentation comment for a U-Boot function.
Also: the purpose of arg0 and arg1 are not clear from this comment.

This is a copy from OP-TEE project, we only use the entry address now.

You can add a back-reference to the original source (i.e. the link into the OP-TEE
GIT) as well, which may be a good idea so people know what this links up with.

However, you should reformat the comment here anyway:
(a)	U-Boot documentation should be consistent (automated tools may harvest
	the comments documenting our exposed functions)
(b)	The meaning of the arguments should be understandable to anyone reading
	the U-Boot source-code without referring to the source of OP-TEE.

Regards,
Philipp.
