25 * Maximum size in memory allocated to the SPL BSS. Keep it as tight as
26 * possible (to allow the build to go through), as this directly affects
27 * our memory footprint. The less we use for BSS the more we have available

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