The SCEG CC6.3S which contains TRNG is only accessible from secure world. Pull 8 random bytes out of the TRNG and pass them to the next stage via DT fragment as /chosen/kaslr-seed property, so Linux can use those random bytes to initialize KASLR in case it is compiled with CONFIG_RANDOMIZE_BASE . Linux before this patch prints early on boot: KASLR disabled due to lack of seed Linux after this patch prints early on boot: KASLR enabled Signed-off-by: Marek Vasut <marek.vasut+renesas@mailbox.org> Change-Id: Ie05473e4e15d348febaca208247541e8a1532534 |
