Can we modify suspend ram sections in power mode switch example to be smaller? [imx7ulp]

Hello,

we wanted run in VLLS mode on A7 and M4 core. We are using RAM target for m4, but m_text region is not enough for us. I was curious if we can move some space from m_m4_suspend_ram/m_a7_suspend_ram regions to m_text region. I see that some part of RAM is stored there and then restored as a result of ROM may overwrite specific part of RAM (but don't see how much and where).

QSPI memory is used for permanent storing/logging data from m4 core.

Hello,

You can modify the RAM space with the linker file, however you can not with ROM space.
