* Public Data
****************************************************************************/
/* These 'addresses' of these values are setup by the linker script.
* They are not actual uint32_t storage locations!
* They are only used meaningfully in the following way:
*
* - The linker script defines, for example, the symbol_sdata.
* - The declaration extern uint32_t _sdata; makes C happy. C will believe
* that the value _sdata is the address of a uint32_t variable _data (it
* is not!).
* - We can recover the linker value then by simply taking the address of
* of _data. like: uint32_t *pdata = &_sdata;
