Merge the contiguous ITCM and DTCM regions into a single region to
prevent failures when loading ELF files with large sections:
remoteproc remoteproc0: powering up imx-rproc
remoteproc remoteproc0: Booting fw image rproc-imx-rproc-fw, size 151824
imx-rproc imx8mp-cm7: Translation failed: da = 0x1f48 len = 0x1fcb0
remoteproc remoteproc0: bad phdr da 0x1f48 mem 0x1fcb0
remoteproc remoteproc0: Failed to load program segments: -22
remoteproc remoteproc0: Boot failed: -22
This approach is the same as commit 8749919defb8 ("remoteproc:
imx_rproc: Merge TCML/U").

Hi,
The ELF I tested had the following data section:
Memory region Used Size Region Size %age Used
m_interrupts: 680 B 1 KB 66.41%
m_text: 6984 B 127 KB 5.37%
m_data: 130224 B 128 KB 99.35%
m_data2: 0 GB 16 MB 0.00%
[100%] Built target hello_world_cm7.elf
Which triggered the error. After this patch, remoteproc was able to boot
and work fine. Thanks!
