29 * possible (to allow the build to go through), as this directly affects
30 * our memory footprint. The less we use for BSS the more we have available

35 * Link BSS to be within SPL in a dedicated region located near the top of
36 * the MCU SRAM, this way making it available also before relocation. Note
37 * that we are not using the actual top of the MCU SRAM as there is a memory
38 * location filled in by the boot ROM that we want to read out without any
39 * interference from the C context.
