+// first flash device, measured in bytes) but the checked flash API accepts one of two types of
+// address:
+//
+// - Flash runtime addresses: the address of some flash-resident data or code in the currently
+//   running image. The flash addresses your binary is "linked at" by the linker.
+// - Flash storage addresses: a flash offset, plus the address base where QSPI hardware is first
+//   mapped on the system bus (XIP_BASE constant from addressmap.h)
+//
+// These addresses are one and the same *if* the currently running program is stored at the
+// beginning of flash. They are different if the start of your image has been "rolled" by the flash
+// boot path to make it appear at the address it was linked at even though it is stored at a
+// different location in flash, which is necessary when you have A/B images for example.
