Historically, when we have an appended device tree and also our
resulting binary will contain the BSS section, we have ensured that
everything will be where it's expected to be by declaring that the BSS
is overlayed with a symbol matches the end of the port of the ELF binary
that is objcopy'd to the binary we concatenate with. This in turn means
that the logic to generate a "pad" file, which is the size found in the
__bss_size symbol, will be correct and then we can concatenate the
device tree and it will begin at __bss_size at run time.
With commit 5ffc1dcc26d3 ("arm: Remove rel.dyn from SPL linker scripts")
we removed this overlay as part of trying to ensure that we met both the
requirements of the device tree to be 8 byte aligned as well as that our
logic to generate the -pad file would match what ended up in the
resulting binary. While it was correct to remove an unused section it
did not solve ultimately solve the problem for all cases.
To really fix the problem, we need to do two things. First, our final
section prior to _image_binary_end must be 8 byte aligned (for the case
of having a separate BSS and so our appended DTB exists at this
location). This cannot be '.binman_sym_table' as it may be empty, and in
turn the ELF type would be NOBITS and so not copied with objcopy. The
__u_boot_list section will never be empty, so it is our final section,
and ends with a '. = ALIGN(8)' statement. Second, as this is the end of
our copied data it is safe to declare that the BSS starts here, so use
the OVERLAY keyword to place the BSS here.

Moving forward, DM firmware will no longer mess with the MAIN_PLL3.
This means MAIN_PLL3 will need to be manually set to 2GHz in order for
the CPSW9G HSDIV to have the correct 250MHz output for RGMII.

Suhaas Joshi <[email protected]> says:
This series starts by replacing hard-coded addresses in firewall
templates that are defined in k3-binman.dtsi, by Kconfigs. Using
Kconfigs makes it easier for someone to move ATF and OP-TEE to another
location, since they wouldn't have to fiddle with the firewall
configurations in dtsi files.
The rest of the commits in this series add firewall configs to each
device's dtsi files.
I have only tested this patch series with TI boards. For non-TI Sitara
boards, respective board maintainers are requested to test the relevant
patch and confirm whether it works.
To test this, I used `k3conf <read|write> <address> [<value>]`. Both of
these operations were disallowed, as expected.

Instead of hard-coding ATF and OPTEE addresses in firewall configuration
templates, use K3_*_LOAD_ADDR. Doing so ensures that if someone moves
ATF/OPTEE regions, the change gets picked up by binman without
explicitly having to modify dts files.

i.MX95 uses System Manager(sm) API to start/stop logical machine or cpu.
There are two modes:
M7 in a dedicated logical machine, use LMM API
M7 and A55 in same logical machine, use CPU API
Extend the driver to using LMM and CPU protocol to manage the M7 core:
- Detect using LMM or CPU API in probe using API scmi_imx_lmm_info().
- Compare linux LM ID(got using scmi_imx_lmm_info) and M7 LM ID(the ID
is fixed as 1 in SM firmware if M7 is in a separate LM),
if Linux LM ID is not same as M7 LM ID(linux and M7 in same LM), use
LMM protocol to start/stop. Whether using CPU or LMM protocol to
start/stop, the M7 status detection could use CPU protocol to detect
started or not. So in imx_rproc_is_running, use scmi_imx_cpu_started to
check the status of M7.
- For above case (2), Use scmi_imx_lmm_power_boot to detect whether
the M7 LM is under control of A55 LM.
- For above case , after using SCMI_IMX_LMM_POWER_ON to check
permission, scmi_imx_lmm_shutdown API should be called to shutdown
the M7 LM.
- Add a new ops imx_rproc_ops_sm.
