mainline inclusion from mainline-v5.10-rc1 commit e4b9146849f246e77da4787657a3a95c1b6d2833 category: feature bugzilla: NA CVE: NA DTS: DTS2021090315802
----------------------------
A number of static variables were not modified. Make them const to allow the compiler to put them in read-only memory. In order to do so, constify a couple of input pointers as well as some local pointers. This moves about 35Kb to read-only memory as seen by the output of the size command.
