Could we also add an explicitly addressed .tdata section as well, would mean renaming the test.
```
MEMORY {
  text_mem (rx) : ORIGIN = 0xFFFFFFFFFFF00000, LENGTH = 0x10000
  tdata_mem (rw) : ORIGIN = 0x100000,           LENGTH = 0x1000
  tbss_mem (rw) : ORIGIN = 0x200000,           LENGTH = 0x1000
}

SECTIONS {
  .text : { *(.text) } >text_mem AT>text_mem
  .tdata 0x100000 : { *(.tdata) } >tdata_mem AT>tdata_mem
  .tbss 0x200000 (NOLOAD) : { *(.tbss) } >tbss_mem AT>tbss_mem
}
```
