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

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