This reverts commit159b6f0e11. Since commit159b6f0e11("caam: Fix CAAM error on startup") the following regression was reported by Tim Harvey: "I've found that this patch causes a regression on an imx8mm board (imx8mm_venice_defconfig) where the first call to caam_rng_read fails here in jr_dequeue but if you call it again it works. With some debugging added: SEC0: RNG instantiated ... Hit any key to stop autoboot: 0 u-boot=> rng list RNG #0 - caam-rng u-boot=> rng 0 10 caam_rng_read caam-rng len=16 run_descriptor_jr_idx idx=0 Error in SEC deq: -1 caam_rng_read_one run_descriptor_jr failed: -1 caam_rng_read caam-rng caam_rng_read_one failed: -5 Reading RNG failed u-boot=> rng 0 10 caam_rng_read caam-rng len=16 run_descriptor_jr_idx idx=0 00000000: ad 2e ad c0 2a 12 27 c4 65 82 66 19 be ef f6 07 ....*.'.e.f..... If I revert your patch caam_rng_read works initially and on subsequent calls." " I ran into this when I was testing lwIP HTTPS as it causes anything that uses dm_rng to fail the first time (such as HTTPS)." Revert it for now to avoid the regression.
