[U-Boot] [PATCH 0/7] Switch WaRP7 BL33 to mbed Linux specific bootflow

[U-Boot] [PATCH 0/7] Switch WaRP7 BL33 to mbed Linux specific bootflow

[Bryan O'Donoghue]

This series switches the BL33 version of WaRP7 to an mbed Linux specific bootflow.

https://os.mbed.com/blog/entry/Introducing-Arm-Mbed-Linux-OS/

The bootflow for our port to the WaRP7 is:

BootROM -> TF-A -> OP-TEE -> u-boot -> Linux with the transition from
OP-TEE to Linux also representing the transition from secure to normal
world.

Here a Trusted-Firmware FIP image contains signed versions of OP-TEE and
u-boot and a u-boot FIT image contains Kernel DTB, initrd, bootscript and
Kernel.

OP-TEE provides a DTB overlay which the bootscript in the FIT image applies
to the kernel DTB, prior to hand-off to Linux.

Some updates to warp7_bl33 and some minor updates to the shared
WaRP7/WaRP7_bl33 code are included.

Bryan O'Donoghue (7):
  warp7_bl33: configs: Enable FIT as the boot.scr format
  warp7: include: configs: Specify image name of bootscript in FIT
  warp7: include: configs: Differentiate bootscript address from
    loadaddr
  warp7_bl33: configs: Enable CONFIG_OF_LIBFDT
  warp7_bl33: configs: Enable CONFIG_OF_LIBFDT_OVERLAY
  warp7: include: configs: Specify an fdtovaddr
  warp7: Specify a default CONFIG_OPTEE_LOAD_ADDR if non provided

[U-Boot] [PATCH 1/7] warp7_bl33: configs: Enable FIT as the boot.scr format

[Bryan O'Donoghue]

This patch switches on FIT verification of boot.scr. After this commit your
boot.scr must be in the FIT format.

[U-Boot] [PATCH 2/7] warp7: include: configs: Specify image name of bootscript in FIT

[Bryan O'Donoghue]

When obtaining the bootscript from a FIT image we need to specify the name
of the bootscript as defined inside of the FIT.

This patch makes a define that appends a "bootscr" parameter to the source
command when compiling up in FIT mode on warp7.

An environment variable is supplied to enable others to use a different
name than "bootscr" as the image name of the boot script in their FIT.

[U-Boot] [PATCH 3/7] warp7: include: configs: Differentiate bootscript address from loadaddr

[Bryan O'Donoghue]

Reusing the loadaddr to load the boot script breaks some of the logic we
want to have around the bootscript/FIT load addresses. Making a dedicated
bootscript address allows us to differentiate the bootscript load address
from the Linux Kernel or OPTEE load address, thus ensuring that no matter
what the load sequence the bootscript and Kernel/OPTEE binary load
addresses do not conflict.

[U-Boot] [PATCH 4/7] warp7_bl33: configs: Enable CONFIG_OF_LIBFDT

In order to switch on DTB overlay support in WaRP7 BL33 we first need to
switch on LIBFDT support. Do that now.

[U-Boot] [PATCH 6/7] warp7: include: configs: Specify an fdtovaddr

[Bryan O'Donoghue]

In the Mbed Linux OS bootflow OP-TEE runs before u-boot and provides a DTB
overlay at 0x83100000.

This overlay should subsequently be merged into the main DTB before handing
over to the kernel.

This patch defines fdtovaddr at 0x83100000.

[U-Boot] [PATCH 7/7] warp7: Specify a default CONFIG_OPTEE_LOAD_ADDR if non provided

[Bryan O'Donoghue]

If no CONFIG_OPTEE_LOAD_ADDR is provided i.e. you are not loading OPTEE
into memory in u-boot, then just set the non-existent CONFIG option to
zero, elsewise stringify(CONFIG_OPTEE_LOAD_ADDR) will return
"CONFIG_OPTEE_LOAD_ADDR" - which looks weird in the u-boot environment.

Instead of implementing a new variable (bootscriptaddr), I think (IMHO) 
it's time to migrate

to distroboot for the WaRP7 (like pico imx7 for instance).


In fact, in this specific case, this allows to use the common 
scriptaddr[1] variable.
FYI, this is a task I am currently working on [2] (work in progress). 
Maybe we could integrate this migration into this series ?

Hi Pierre,

I've applied your patch on-top of of a 3 day old master

* 60277e4bcc - (HEAD) warp7: add distroboot support (27 hours ago)
* 4ca7700d2c - imx: Use a convenient default value for SYS_MALLOC_F_LEN 
(27 hours ago)
* 48372a5af6 - Remove whitelist entry for CONFIG_CRC32 (3 days ago)
* 4ad2c8953d - Remove #define CONFIG_CRC32 (3 days ago)
* 661bbc50d3 - mtd: ubi: Remove select for non existent option (3 days ago)
* 2b841dba5c - cmd: ubifs: Remove select for non-existent option (3 days 
ago)
* b8de00c671 - Remove whitelist entry for CONFIG_GPIO (3 days ago)
* 26680b9f3a - sysreset: select DM_GPIO instead of GPIO (3 days ago)
*   927a37df9f - Merge branch '2019-05-09-master-imports' (3 days ago)

should this apply in isolation ?

I get a dead-loop on USB CDC ethernet...

It seems your problem is here. In fact, if this action fail,
U-Boot try to run network booting (PXE, defined in warp7.h).

For your tests, the command 'bootcmd_mmc0' is sufficient.

FYI, my setup is not exactly the the same as
you have (with the CONFIG_FIT_SIGNATURE option enabled for sure).
I'm going to do some tests with this configuration.

So do you need a boot.scr for this patch to work, how will that affect 
current users who rely on the u-boot env only ?

In fact, by using the Generic Distro Concept, we can also use the 
extlinux file, as explained in[1].
Example on WaRP7 :

=> run bootcmd_mmc0
switch to partitions #0, OK
mmc0(part 0) is current device
Scanning mmc 0:1...

    Using Device Tree in place at 83000000, end 83009908


Regarding your question, it seems that is now the standard on many 
platforms [2].
In fact, instead of keeping a custom environment, it is better to use a 
more
generic approach by switching to disto config (with boot.scr, extlinux, 
and so on).

For sure, we can customized the CONFIG_BOOTCOMMAND variable in patch.

Right.

This smells like a bigger change to me then, since we have to account 
for how we transition current users from their u-boot environment to 
distroboot.

It sounds to me like a series of patches around this one topic.

So, I think it is worthwhile exploring that set of changes but, I do 
think we should do it separately to this set :)

Indeed, it seems you're right.
I'll send this later, means once your patches are integrated ;).
I am convinced that it's better to work on your series first.

Just a quick remark, can you share more informations
about the setup ? so I can test your series on my side ;)
