- In ti-u-boot-2024.04, the config fragment to disable splashscreen
is now renamed to am62x_evm_prune_splashscreen.config [1]
Hence, update UBOOT_CONFIG_FRAGMENTS for the same.
- Add UBOOT_CONFIG_FRAGMENTS:bsp-ti-6_1 which ensures that
am62pxx-evm machine configuration still supports Display Cluster usecase [2]
with ti-u-boot-2023.04

On a side-note,
The uEnv.txt also needs to be updated as need to prefix ti in name_overlays as
otherwise we get below error :
[2024-07-04 15:57:12.135] Failed to load
'/boot/dtb/k3-am62p5-sk-microtips-mf101hie-panel.dtbo'

[2024-07-04 15:57:12.151] ## Flattened Device Tree blob at 88000000
After setting as below, it works fine :
setenv name_overlays ti/k3-am62p5-sk-microtips-mf101hie-panel.dtbo
ti/k3-am62p5-sk-dss-shared-mode.dtbo $name_overlay
Above can go as a separate patch and there could be multiple platforms
affected, please verify.
Just a clarification for folks in mailing list,
The uEnv.txt only for Display Cluster usecase of AM62P is updated in
meta-tisdk [1]
& is independent of meta-arago. Will take an action to update the
uEnv.txt in meta-tisdk
post we have this patch integrated to master/scarthgap.
For other platforms, by default the uEnv.txt is empty & it comes from
meta-arago [2].
So, rest all platforms aren't affected!
