This reverts commit 159b6f0e11.
Since commit 159b6f0e11 ("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.
