At boot, U-Boot will copy ATF/OPTEE certificates and DM into a LPM memory
region.
Passing it to TIFS with TISCI_MSG_LPM_SAVE_ADDR
https://software-dl.ti.com/tisci/esd/latest/2_tisci_msgs/pm/lpm.html#lpm-msg-lpm-save-addr
Before suspend, TIFS will save and encrypt TFA context and its own minimal
context.
At resume, U-Boot will tell TIFS to restore and decrypt data from this
memory region.
So, U-Boot needs to parse the device tree, looking for
"/reserved_memory/lpm-memory"
Moreover, from reserved-memory.yaml:
Following the generic-names recommended practice, node names should
reflect the purpose of the node (ie. "framebuffer" or "dma-pool").
So @lpm-memory seems to reflect the purpose.
Changes since v1:
- add specific lpm region for j742s2 and j784s4 instead of the common
one since the addresses are not the same.
- add j721s2 lpm_memory_region
- change j722s addresse to prevent holes
- link to v1: https://lore.kernel.org/lkml/20260312113446.1857592-1-p-mantena@ti.com/

From: Prasanth Babu Mantena <p-mantena@ti•com>
For TI SOCs J7200, J784S4, J722S, J721s2 which support low power modes,
a chunk of memory is reserved for LPM meta data, which is needed for
saving ATF context and the certificate information of ATF and OPTEE and
DM image. This LPM metadata area is firewalled to be accessed only by
TIFS.
U-Boot/TIFS will use this area to save and restore:
- ATF context
- ATF certificate information
- OPTEE certificate information
- DM image
https://software-dl.ti.com/tisci/esd/latest/2_tisci_msgs/pm/lpm.html#lpm-msg-lpm-save-addr
U-Boot has to parse and retrieve this area from the device tree, thus
@lpm-memory node are used instead of the generic @memory.

Split this up into platform wise. I dont understand why you'd not modify
the ipc-firmware.dtsi and use the phandle similar to https://lore.kernel.org/all/20260318-topic-am62a-ioddr-dt-v6-19-v3-4-c41473cb23c3@baylibre.com/
Split the patches per ipc-firmware.dtsi as required.

Actually, after being loaded from storage at boot time by U-Boot R5 SPL,
the DM image is copied in this memory, so that it doesn't have to be
loaded from storage at resume. (This speeds up the resume time)
For the context:
At resume, U-Boot R5 SPL is executed and detects that the board is
resuming (with a flag set in the PMIC), then it:
- brings out of retention the DDR
- retrieves the LPM memory region from DTS
- authenticates certificates from LPM memory region and applies firewalls
- asks TIFS to restore TFA and its own minimal context
- starts TFA on remote proc
- loads back DM image from memory and jumps to DM

The wkup_r5fss0_core0_memory_region can't be used in our case because
the DM memory isn't retained during suspend.
For Sitara, the LPM metadata are stored in the DM DDR, but here, as the
DM memory is not kept during suspend, the LPM meta-data is stored in
another memory region, so I don't think I can use this phandle.

I would happily use the phandle, but as this memory is not related to
the DM DDR, I don't think I can.
Thanks!
