/* ##### EMBASSY NOTE
Originally from https://github.com/rust-embedded/cortex-m-rt/blob/master/link.x.in
Adjusted to put everything in RAM
*/
/* # Developer notes
- Symbols that start with a double underscore (__) are considered "private"
- Symbols that start with a single underscore (_) are considered "semi-public"; they can be
overridden in a user linker script, but should not be referred from user code (e.g. `extern "C" {
static mut __sbss }`).
- `EXTERN` forces the linker to keep a symbol in the final binary. We use this to make sure a
symbol if not dropped if it appears in or near the front of the linker arguments and "it's not
needed" by any of the preceding objects (linker arguments)
- `PROVIDE` is used to provide default values that can be overridden by a user linker script
- On alignment: it's important for correctness that the VMA boundaries of both .bss and .data *and*
the LMA of .data are all 4-byte aligned. These alignments are assumed by the RAM initialization
routine. There's also a second benefit: 4-byte aligned boundaries means that you won't see
"Address (..) is out of bounds" in the disassembly produced by `objdump`.

Possible solutions, from most likely to less likely:
- Link to a svd2rust generated device crate
- Check that you actually use the device/hal/bsp crate in your code
- Disable the 'device' feature of cortex-m-rt to build a generic application (a dependency
may be enabling it)
- Supply the interrupt handlers yourself. Check the documentation for details.");
